▼ Energy efficiency provides a feasible way by which transport emissions can be reduced, air quality can be improved, and security of supply can be increased. In light of energy security and climate change, improving efficiency should be relatively high on the Government’s agenda, also because it can contribute to economic efficiency. This thesis compares the legal framework in New Zealand with the regulatory approach of the United States, the European Union, Japan, and Australia. The discussion shows that the legislative framework in New Zealand gives a disjointed and complicated approach to strategic planning which has resulted in a lack of cohesion which requires future reform. However, the proposed amendments to the primary legislation that affects planning in transport will not be helpful in improving energy efficiency, and research shows the overall focus of central government is not consistent with international thinking. Further, the targets for energy efficiency in transport are weak and require nothing more than business as usual. Even though policies to promote energy efficiency exist, the isolated instruments chosen have limited results. Overall, the regulatory and policy approach by central government gives a piecemeal and unsatisfactory outcome. The approach by some local governments however, shows a commitment to improve energy conservation. To show internationally that New Zealand is committed to reducing our GHG emissions, reform is needed. New Zealand needs regulation to reduce the average age of the vehicle fleet and to encourage more efficient vehicles. This should consist of vehicle standards, a charge on vehicle CO₂ emissions, and improved information measures. These above measures need to be integrated. Further policy instruments are needed to encourage the use of alternative fuels, electric vehicles, and eco-driving. Perhaps most importantly, what is needed is a philosophical shift by Government, who needs to lead by example and to view energy efficiency as a priority rather than a desired outcome.

▼ Worldwide, rural road networks serve a vital link in the chain leading goods to markets and people to places. The efficiency of rural road network services is influenced by road-related investment and policy decisions. Reaching good decisions, however, is complicated by: interrelationships among policy, investment, road use, road performance, and rural economies; and combinatorial challenges involving the distribution of discrete policy and investment arrangements across networks.The main objective of this study is to address this complex problem as it pertains to rural road networks in Saskatchewan. Rural roads in Saskatchewan are suffering under increasing volumes of heavy truck traffic motivated principally by recent changes in the grain handling and transportation system. To address this problem, Saskatchewan Department of Highways and Transportation is considering a range of haul policy and road structure investment options. The question is, what (spatial) arrangement of available policy and investment options best meets this challenge. To answer this question, a cost-based standard is incorporated within a network design modeling approach and solved using custom algorithmic strategies. Applied to a case study network, the model determines a demonstrably good arrangement of costly road structure modifications under each considered policy option. Resulting policy-investment combinations are subsequently ranked according to total cost and equivalent net benefit standards. A number of important findings emerge from this analysis. Policy and investment decisions are linked; spatial arrangement of road structure modifications is contingent on the haul policy regime in place. Road performance and use characteristics are indeed sensitive to policy and investment decisions. Optimal budget levels computed by the model contradict perceptions that rural road networks in Saskatchewan are grossly under-funded. Despite best intentions, ill-considered policy can actually reduce the net benefits of road provision and use. Model application and design limitations suggest promising avenues for future research. These include: model larger networks in Saskatchewan and beyond; determine optimal road budgets under benefit-cost standards reflecting competing economic needs; employ model within regional economic planning investigations to forecast road-related implications; and model policy endogenously to aid design of heavy haul sub-networks and to address questions concerning network expansion or contraction.

▼ Road transport is the backbone of the real economy but its future health depends on providing better environmental and economic benefits, not simply more transport. And hence it calls for an efficient transport to improve the economic growth that takes into account the emissions that drives climate change. Vehicle utilization level is a measure of how efficiently the freight sector is transporting goods. When transporters cannot arrange for a return shipment, the empty truck move doesn‟t generate revenue, but accumulates costs in labor, equipment wear, and fuel and produce hazardous emissions. Currently, in Ethiopia, the gap in trade balance is very wide resulting in poor vehicle utilization level (for transport between the capital city and port), transparency is lacking and responsibilities are fragmented, and hence that the current road freight transport system is not taking advantage of its large scale. The main objective of this research was focused on providing a better understanding of goods transport along Addis Ababa – Djibouti corridor and describing the impact of vehicle utilization level inefficiency on the environment with respect to CO2 emission and on the economy of the country in terms of vehicle operating costs and loss of foreign currency in Ethiopia. A combination of both quantitative and qualitative research methods were employed in this study. To reflect on the efficiency performance of the freight transport in Ethiopia particularly along Addis Ababa – Djibouti corridor, the goods flow, different stakeholders and constraints were mapped out and discussed based on the literature review and the interviews. Secondary data was collected from the different stakeholders and was analyzed using formulas from literature reviews to assess the load factor and empty running rates along Addis Ababa – Djibouti corridor. CO2 emission, truck operating costs, trade balance deficit and the loss in foreign currency due to the empty running trucks was also estimated. The study showed that the trade balance deficit is found to be the main transport inefficiency factor amounting to 90% trade imbalance, The rate of empty running which mainly results from the trade balance deficit is estimated to be 46% and the country is losing around 300 million dollars of foreign currency per year accompanied by a 200,000tons of unnecessary CO2 emission per year. This paper does not attempt to suggest that partly loaded or empty running trucks can be fully eliminated; however there is a room for improving the economic sector of the country by increasing export volume while sustaining the same CO2 emission level if not decreasing the disadvantage that the emission contributes to the environment.

▼ Rail transport refers to the transportation of various commodities, goods and services traded as cargo and freight within South Africa and out of South Africa for export to the other Southern African communities (SADC region), the rest of Africa and other continents of the world. It also refers to the imports into South Africa from the regions mentioned. Competitiveness relates to a country or company’s available resources and supporting policies and regulations in place which allow them to compete and do business locally, internationally and globally while improving the country’s economy and the company’s profitability. There are different criteria that can be used to determine the level of competitiveness, depending on each company or country’s capabilities. In the past years, the progress and development of the South African rail industry has been neglected and this has resulted in the rail transportation not being used. Railway line maintenance has become a challenge and service delivery is below customer expectations. Road transport has better availability and reliability, which has led companies to prefer road transport for freight. The main objective of this study is to reach a detailed understanding of the views of freight rail transport consumers and the impact of rail transport on the economic competitiveness of South Africa. Another important objective is to present the study in a format that is easily understandable. The approach adopted for this study is quantitative and uses a survey research questionnaire which was distributed to freight rail transport customers and providers. The data collected from the questionnaire was submitted to a statistical consultant service at North-West University. The statistical consultant analysed the data using the SPSS statistics computer programme to arrive at the results presented in this study. The overall findings from this study are that companies that use roads to transport freight do so because of the unavailability and unreliability of the freight rail transport provider Transnet Freight Rail and that these companies opt for road transport because they use a ‘just in time’ (JIT) system whereby a small quantity of stock is transported continuously which Transnet Freight Rail (TFR) does not accommodate. These factors have resulted in TFR’s poor service delivery. Therefore, a market demand strategy has been initiated by TFR to improve the performance of the company. It is important to note here that freight rail transport should concentrate on improving service delivery and not only on increasing capacity. The research participants indicated that the TFR objective to move freight back to rail could be accomplished. This will lessen the burden and damage to South African roads and reduce traffic congestion and accidents caused by trucks on the roads. It will also increase employment opportunities and the country’s economic competitiveness while reducing transport costs. All these aspects will make a significant impact on the economy of the country.

This study was carried out aiming to identify the economical-financial efficiency of small hosting establishments (SHE) along the Estrada Real (the Royal Road) through the Data Envelopment Analysis ( DEA) methodology , so as to investigate the existence of homogeneity in the management efficiency in such establishments, build comparative efficacy levels (productive, technical and scale); analyze the enterprisesâ risk and reward and, finally, map up new efficiency patterns for the SHEâs taken as âinefficientâ in the SÃo JoÃo del-Rei and Tiradentes region. For that purpose a quantitative analysis was carried out, with exploratory aims, of segmentâs historical information, bookkeeping and account statements of the small tourism-related enterprises, over the year of 2008. The sample evidenced that productive efficacy is barely homogeneous. Once the differences inherent to the nature of each one of the decision-making units became known, the rising of large efficiency discrepancies was expected. Nevertheless, that was not verified. In the analysis of the SHEâs technical efficiency, the financial management question proved to be quite homogeneous, as 50% of the analyzed endeavors were classified as 100% efficient, management-wise. However the scale inefficiency was verified through 83.66% of the sample. Several decision-making units (DMU) taken as inefficient offered high risk to the entrepreneurs while several efficient DMUâs offered high rewards and low risk. The DEA, allied to the analysis of risk and reward contributes to a better adaptation of a economical-financial management of the âinefficientâ enterprises and, consequently, to the increase in competitiveness of the intangible product ER (RR). This is not a revolutionary study: the call for analysis rises from a research-thirsty segment in which the universe of possibilities remains unknown.

Este estudo foi realizado com os objetivos de identificar a eficiÃncia econÃmico-financeira dos pequenos meios de hospedagem (PMH) da Estrada Real (ER), utilizando-se a metodologia de AnÃlise EnvoltÃria de Dados (DEA); verificar a existÃncia de homogeneidade na eficiÃncia da gestÃo destes empreendimentos, construir nÃveis comparativos de eficiÃncia (produtiva, tÃcnica e de escala); analisar o risco e o retorno das empresas e, por fim, mapear novos padrÃes de eficiÃncia para os PMH tidos como âineficientesâ na regiÃo de SÃo JoÃo del-Rei e Tiradentes. Para tanto, foi realizada uma anÃlise quantitativa, com finalidade exploratÃria, das informaÃÃes histÃricas do setor, da escrituraÃÃo e das demonstraÃÃes contÃbeis das pequenas empresas turÃsticas, no exercÃcio social de 2008. A amostra evidenciou que a eficiÃncia produtiva Ã pouco homogÃnea. Conhecidas as diferenÃas inerentes Ã natureza de cada unidade tomadora de decisÃo, esperava-se o surgimento de grandes discrepÃncias de eficiÃncia. No entanto, nÃo foi o que se observou.

Šio darbo tikslas – atlikti ekspedicinių ir transporto įmonių veiklos efektyvumo lyginamąjį tyrimą. Tyrimui turi įtakos esama situacija transporto sektoriuje, todėl darbe įvertinamos kelių transporto sektoriaus plėtros perspektyvos bei analizuojamos krovinių vežimo apimtys per pastaruosius 5 metus. Darbe remiamasi apklausoje dalyvavusių respondentų atsakymais apie jų įmonių veiklos efektyvumą. Atlikus tyrimą buvo nustatyta, kad ekspedicinė veikla (dabartinėmis sąlygomis) yra efektyvesnė, nei vežimo. Tam turėjo įtakos tai, kad 2008 metai buvo nuostolingi vežėjams, nes didėjo degalų kainos bei mažėjo krovinių vežimo apimtys. Remiantis respondentų atsakymais, galima teigti, kad transporto veikla tampa mažiau pelninga, nes beveik pusė jų, jeigu tektų rinktis iš naujo, kuo užsiimti, pasirinktų kitą veiklą. Kita dalis respondentų nurodė, kad užsiimtų ekspedijavimu. O tai reiškia, kad ekspeditorių padėtis yra lengvesnė nei vežėjų. Tik maža dalis apklaustųjų pasirinktų vežimo veiklą. Darbą sudaro 5 dalys: įvadas, analitinė-metodinė dalis, eksperimentinė-tiriamoji dalis, išvados ir siūlymai, literatūros sąrašas. Darbo apimtis – 81 p. teksto be priedų, 13 iliustracijų, 3 lentelės, 52 bibliografiniai šaltiniai.

The aim of this work - to perform comparative analysis of forwarding and transportation companies activity efficiency. The present situation in the transport sector has influence upon the analysis, therefore in the work, the perspectives of road transport sector expansion are evaluated, also cargo transportation volumes during the latter 5 years are analyzed. The work is based on the answers of the respondents, who participated in the survey - about the efficiency of their companies' activity. When the analysis was made, it was established, that the forwarding activity (in the present circumstances) is more effective than the transportation activity. Also this fact, that the year 2008 was loss-making to the carriers, because the fuel prices increased and the volumes of cargo transportation decreased, had influence on the research results. On the grounds of respondent answers, it can be stated, that transportation activity becomes less profitable, because nearly half of the respondents, if they had a possibility to choose newly what activity to take, would choose the other activity. Other part of the respondents has indicated that they would use forwarding. And this means, that the condition of forwarders is easier than the carriers' condition. Only the little part of the respondents would choose the carrier activity.

L’imperméabilisation des surfaces et l’augmentation des débits de pointe sont liés au développement croissant des environnements urbains. Avec cette croissance urbaine, les processus de ruissellement sont largement affectés et représentent un secteur dans lequel des actions doivent être entreprises afin d’assurer à la fois le développement économique et la protection de l’environnement et des ressources en eau. Le ruissellement est fréquemment associé à des pollutions diffuses (Non Point Source) qui ne sont généralement pas prises en compte dans les dispositifs classiques de régulation hydraulique. L’objectif de cette recherche était d’évaluer les performance de dispositifs de filtration sur les micro particules polluantes diffuses issues des chaussées routières et des déversoirs d’orages des réseaux d’assainissement unitaires (Combined Sewer Overflows – CSOs). Le protocole expérimental implique de mesurer, dans un premier temps, la taille et les caractéristiques des particules polluantes diffuses et ensuite, de réaliser une procédure identique à la sortie des installations de filtration et de traitement. Les modifications dans la distribution de la taille des particules et de leurs caractéristiques sont alors analysées. Les quatre principaux dispositifs de filtration disponibles - Expanded Polypropylene (EPP), Expanded polystyrene (EPS), Perlite pour les particules flottantes et Zeolite pour les non flottantes – ont été implanté sur un équipement de test et les résultats comparés. Une modélisation 3D (CFD) a été réalisée afin d’optimiser la conception de la disposition de filtration.

The impermeable area and the peak discharge volume have been consistently increasing due to widening of city development and renewal. Thus, distortion of water cycle has been serious problem compared to the past. When it comes to NPS pollution, lack of information on the load and characteristics of pollutants led to the insufficient reduction measures. The purpose of this study is to investigate the effectiveness of filters to control micro particles from non-point sources, especially from road runoff and Combined Sewer Overflows (CSOs). The study first examined the particle size and characteristics of NPS pollutants, and then analyzed the head loss, treatment efficiency and changes in particle size distribution before and after the treatment using device type facilities. The four most commonly used filters - Expanded Polypropylene (EPP), Expanded polystyrene (EPS), and Perlite as floatability filtering materials, and Zeolite as non-floatability - were compared. The upward-type filtering equipment was manufactured for the lab experiment, and CFD modeling was conducted to identify optimized design parameters. The results showed that the ratio of micro particles(＜100 ㎛), to which the filtering process can be applied, was highest in samples from the road runoff, followed by one from the bridge, and from the parking lot. The results using road runoff displayed that EPP was most efficient with ratio of 89% to treat SS and COD.

▼ New heavy-duty vehicle regulations have caused significant reductions in hazardous air pollutants, such as particulate matter (PM) and nitrogen oxides (NO_x), due to better engine management and utilization of advanced after-treatment systems. The University of Denver has collected data for gaseous and PM emission measurements from on-road heavy-duty vehicles (HDVs). The On-Road Heavy-Duty Vehicle Emissions Measurement System (OHMS) collected fuel specific emission information on individual HDVs of in-use fleets at two California locations in the spring of 2013, 2015 and 2017. These complimentary fleets, studied over multiple years, produced 7,075 measurements of gaseous and particle emission data providing the basis to quantify on-road HDV emission trends and compare a variety of factors that influence on-road emissions. The Port of Los Angeles contributes a fleet fully equipped with diesel particulate filters (DPFs) that had an observed PM increase of 30% in 2017 from 2013, but the fleet average is highly dependent on the fraction of high emitters. The second fleet measured was at the Cottonwood weigh station in Northern California, regulated at the state level and with slower fleet turn over, fleet PM emissions decrease (76% between 2013 and 2017) but at a slower rate than at the Port. Additionally, heavy and medium-duty vehicles were measured at a second weigh station in Southern California. The Fuel Efficiency Automobile Test (FEAT) was used to collect on-road fuel specific emissions for HDVs and MDVs at the Peralta weigh station near Anaheim, CA, resulting in 2,315 measurements. The HDV’s data added to measurements from 1997, 2008, 2009, 2010 and 2012 at this location. Two FEAT systems, one traditionally mounted atop scaffolding to collect emissions from HDVs with elevated exhaust stacks and a second, ground-level system were used for the first time to measure emissions from both MDVs and HDVs with ground-level exhaust. Introduction of new technologies show diminished NOx and PM emissions as HDVs saw a 55% NOx decrease since 2008 and a 33% reduction in IR %opacity. The MDV fleet was 2.1 years older than the HDV fleet and MDVs NO_x emissions show reductions approximately 2 model years (2014) earlier than HDVs.

The present doctorate aims to: the development of a detailed test protocol for the generation of consistent and repeatable data for the validation of energy consumption of vehicle simulation models, the development of a template model topology, applicable to all conventional vehicles, to facilitate and guide the modeling process, the generation of a large pool of highly accurate simulation data which are being used for the development and validation of CO2MPAS tool, the analysis and quantification of the impact of WLTP introduction on the certification procedure compared to the old NEDC, the development of modeling approaches of state-of-the-art energy efficiency technologies in vehicle simulation models and to the development of a methodology for the calculation of CO2 emissions in real world driving conditions.For this reason the European vehicle fleet has been divided in characteristic segments as a function of transmission type, fuel type, displacement and engine aspiration type. A vehicle was selected for each one of the segments which was measured in the NEDC and WLTP protocols and for which a simulation model was developed in the Cruise software of the company AVL GmbH. The model validation has been conducted by comparing their results against their respective measurements for four different criteria that has been established by the European Commission in the context of “WLTP/NEDC Correlation exercise” research program. The developed vehicle simulation models combined with fourteen different energy efficiency technologies and a database has been developed which was used for the development and validation of CO2MPAS tool. Finally, the developed vehicle simulation models and their results were used in a scenario for the prediction of vehicle fleet average CO2 emissions for 2030 and to investigate their usage in a potential real-world driving type approval.Concluding, the dominant reason for the ΔCO2 between WLTP and NEDC was found to be the different inertia test mass and the applied driving resistance, Most of the investigated technologies have a larger average effect in NEDC rather than WLTP since manufacturers developed and optimized these technologies to comply with the NEDC legislation. Moreover, using a generic vehicle simulation model with data from public sources and the developed database it was shown that the real world fuel consumption simulation can be successful, the future composition of vehicle fleet cannot be predicted but rather only estimated due to its dependence on macro economy, CO2 regulatory framework, customer demographics etc. Finally, optimizations towards the new procedure by vehicle manufacturers will still be possible but yet, it is unclear how are they going to be adopted and what will their CO2 effect be.

▼ Our society is heavily and intrinsically dependent on energy transformation and usage. In a world scenario where resources are being depleted while their demand is increasing, it is crucial to optimize every process. During the last decade the concept of energy efficiency has become a leitmotif in several fields and has directly influenced our everyday life: from light bulbs to airplane turbines, there has been a general shift from pure performance to better efficiency. In this vein, we focus on the mobility and tractive efficiency of off-road vehicles. These vehicles are adopted in military, agriculture, construction, exploration, recreation, and mining applications and are intended to operate on soft, deformable terrain. The performance of off-road vehicles is deeply influenced by the tire-soil interaction mechanism. Soft soil can drastically reduce the traction performance of tires up to the point of making motion impossible. In this study, a tire model able to predict the performance of rigid wheels and flexible tires is developed. The model follows a semi-empirical approach for steady-state conditions and predicts basic features, such as the drawbar pull, the driving torque and the lateral force, as well as complex behaviors, such as the slip-sinkage phenomenon and the multi-pass effect. The tractive efficiency of different tire-soil configurations is simulated and discussed. To investigate the handling and the traction efficiency, the tire model is implemented into a four-wheel vehicle model. Several tire geometries, vehicle configurations (FWD, RWD, AWD), soil types, and terrain profiles are considered to evaluate the performance under different simulation scenarios. The simulation environment represents an effective tool to realistically analyze the impact of tire parameters (size, inflation pressure) and torque distribution on the energy efficiency. It is verified that larger tires and decreased inflation pressure generally provide better traction and energy efficiency (under steady-state working conditions). The torque distribution strategy between the axles deeply affects the traction and the efficiency: the two variables canâ t clearly be maximized at the same time and a trade-off has to be found.

▼ Practices in winter road maintenance are dependent on the climate and weather impacting roads and the road users’ requirements. As in many other fields of transportation, it is of interest to investigate fuel efficiency potentials in the different aspects of the road maintenance area. The main focus of this thesis was on investigating energy use in winter road maintenance activities in southern Sweden. It is crucial to understand which parameters are of the largest significance in slipperiness, as well as to investigate the weather information that the operations are based on, since the climate is the reason for requiring winter road maintenance in the first place. The original energy use needs to be set, to be able to know whether efficiencies are made. In this thesis, two approaches were taken to understand if existing fuel consumption models for heavy-duty vehicles could be applied within winter road maintenance or whether in-vehicle fuel data such as data from vehicle manufacturers should be used instead. Finally efficiency potentials were explored with the use of a route optimisation programme for winter road maintenance practices. The climate data analyses showed that frost warnings are the most common type of slipperiness in the southern parts of Sweden. If such warnings were to be under- or overestimated, it could have a large impact on the energy used, since unnecessary slipperiness treatments could be performed. Furthermore, the mobile water depth measurements indicated that it is possible to detect differences in water depth along roads and that exit ramps could be interesting in terms of changed treatments, since the water depths were quite large on those ramps. From the use of the fuel consumption model included in the Swedish National Road and Transport Research Institute, or VTI, winter model, it was concluded that anti-icing would not be energy efficient in terms of traffic energy use, since drivers tend to drive at higher speeds on salted roads. Snow density and amount would however, impact fuel consumption, which is why the removal of snow could save traffic energy use. The best method to evaluate energy use during winter road maintenance was the use of in-vehicle data. The existing fuel consumption model used in this thesis, underestimated the fuel use, which implied that the energy use in winter road maintenance practices depends on other aspects than what was stated in the model calculations. Such other aspects seemed to be the weather and way of work that in turn demand significant changes in speed. Changes in speed was also regarded as a potential efficiency measure, as the velocities of the heavy-duty vehicles seemed on average to be below what was estimated as the most fuel-efficient speed for this type of vehicle. Using the route optimisation programme further put a way for evaluating efficiency potentials. It was shown that installing underground heating systems or road surface–installed salt spreaders at strategic locations could save fuel use, as would changing operations from sanding to…

Chaque année, des millions de personnes meurent et beaucoup d'autres subissent des séquelles graves à la suite d'accidents de la route. Malgré une multitude d’initiatives, le nombre de cas mortels et d'accidents graves augmente chaque année en engendrant des problèmes préoccupants à la fois sociaux, économiques et sanitaires. En raison de leur nombre élevé et de l'absence de protection personnelle, plus de la moitié de ces décès concerne les usagers vulnérables (en anglais, vulnerable road users - VRU) regroupant les piétons, cyclistes et motocyclistes. Les appareils mobiles, combinés à la technologie de Fog Computing (ou informatique géodistribuée, ou même informatique en brouillard), représentent une solution réaliste à court terme pour les protéger en les avertissant de l’imminence d'un accident de circulation. L’omniprésence des appareils mobiles et leurs capacités de calcul élevées font de ces appareils un élément important à considérer dans les solutions de sécurité routière. Le Fog Computing offre des fonctionnalités adaptées aux applications de sécurité routière, puisqu’il s’agit d’une extension du Cloud Computing permettant de rapprocher les services informatiques, le stockage et le réseau au plus près des utilisateurs finaux. Par conséquent, dans cette thèse, nous proposons une architecture réseau sans infrastructure supplémentaire (PV-Alert) pour des fins de sécurité routière et reposant uniquement sur les appareils mobiles des VRU et des conducteurs sur la route avec l’aide du concept de Fog Computing. Les données géographiques et cinématiques de ces appareils sont collectées et envoyées périodiquement au serveur fog situé à proximité. Le serveur fog traite ces données en exécutant un algorithme de calcul de risque d’accident de circulation et renvoie des notifications en cas d'accident imminent. L’évaluation de cette architecture montre qu’elle est capable de générer des alertes en temps réel et qu’elle est plus performante que d’autres architectures en termes de fiabilité, d’évolutivité et de latence.

Annually, millions of people die and many more sustain non-fatal injuries because of road traffic crashes. Despite multitude of countermeasures, the number of causalities and disabilities owing to traffic accidents are increasing each year causing grinding social, economic, and health problems. Due to their high volume and lack of protective-shells, more than half of road traffic deaths are imputed to vulnerable road users (VRUs): pedestrians, cyclists and motorcyclists. Mobile devices combined with fog computing can provide feasible solutions to protect VRUs by predicting collusions and warning users of an imminent traffic accident. Mobile devices’ ubiquity and high computational capabilities make the devices an important components of traffic safety solutions. Fog computing has features that suits to traffic safety applications as it is an extension of cloud computing that brings down computing, storage, and network services to the proximity of end user. Therefore, in this thesis, we have proposed an…

▼ Road transport is responsible for a significant share of the global GHG emissions. In order to address the increasing trend of road vehicle emissions, due to its heavy reliance on oil, Nordic countries have set ambitious goals and policies for the reduction of road transport GHG emissions. Despite the fact that the latest developments in the passenger car segment are leading towards the progressive electrification of the fleet, the decarbonization of heavy-duty vehicle segment presents significant challenges that are yet to be overcome. This study focuses, on the first part, on the regulatory framework of fuel economy standards of road vehicles, highlighting the absence of a European regulation on fuel efficiency for the heavy-duty sector. Energy efficiency technologies can be grouped mainly in vehicle technologies, driveline and powertrain technologies, and alternative fuels. The fuel efficiency of HDVs can be positively improved at different vehicle levels, but the technology benefit and its economic feasibility are heavily dependent on the vehicle type and the operational cycle considered. The electrification pathway has the potential of reducing the carbon emission to a great extent, but the current battery technologies have proven to be not cost efficient for the heavy vehicles, because of the high purchase price and the low range, related to the battery cost and inferior energy density compared to conventional liquid fuels. A scenario development model has been created in order to estimate and quantify the impact of future developments and emission reduction measures in Finland, Sweden and Norway for the timeframe 2016-2050, with a focus on 2030 results. Two scenarios concerning the powertrain developments of heavy-duty vehicles and buses have been created, a conservative scenario and electric scenario, as well as vehicle efficiency improvements and fuel consumption scenarios. Additional sets of parameters have been estimated as input for the model, such as national transport need and load assumptions. The results highlight the challenges of achieving the national GHG emission reduction targets with the current measures in all three countries. The slow fleet renewal rates and the high forecasted increase of transport need limit the benefits of alternative and more efficient powertrains introduced in the fleet by new vehicles. The heavy-duty transport is expected to maintain its heavy reliance on diesel fuel and hinder the improvements of the light-duty segments. A holistic approach is needed to reduce the GHG emissions from road transport, including more efficient powertrains, higher biofuel shares and progressive electrification.

▼ In the late 1980s and early 1990s few transportation agencies around the world considered performance-based specifications as an alternative to improve the efficiency of the services provided to the public. These initiatives are better known as Performance-Based Road Maintenance (PBRM). PBRM calls for performance-based work, in which a desired outcome is specified rather than a material or method. This type of specification promises to be an excellent tool to improve government efficiency in maintaining transportation networks; however, without proper monitoring, it could likely yield adverse outcomes. Since PBRM is relatively new, the availability of reliable and comprehensive sets of guidelines to evaluate the effectiveness and efficiency of this type of specifications in the roadway maintenance arena is limited. Transportation agencies currently rely on criteria and procedures they have had developed from their traditional methods used to evaluate performance. Unfortunately, some of these procedures cannot appropriately assess the benefits, if any, accrued by the government as a result of implementing performance-based specifications for the maintenance of the roadway system. This research presents the development of a framework for monitoring PBRM more comprehensively and accurately. The framework considers the assessment of five main areas – Level of Service Effectiveness, Cost-Efficiency, Timeliness of Response, Safety Procedures, and Quality of Services – in order to guarantee the comprehensiveness and reliability of the evaluation process. The major contribution of this framework is to provide transportation agencies with guidelines for evaluating the effectiveness and efficiency of PBRM as an alternative delivery method to maintain and preserve the roadway system.

▼ For the last two decades, the road maintenance concept has been gaining tremendous attention. This has brought about new institutional changes, predominant of which is the challenge for maintenance managers to achieve maximum performance from the existing road system. Such challenge makes it imperative to implement comprehensive systems that measure road maintenance performance. However, the road maintenance performance measurement systems developed and implemented by researchers and state departments of transportation (DOTs) mainly focus on the effectiveness measures, e.g., the level-of-service. Such measurement systems do not sufficiently elaborate on the efficiency concept, e.g., the amount of resources utilized to achieve such level-of-service. Not knowing how â efficientâ state DOTs are in being â effectiveâ can lead to excessive and unrealistic maintenance budget expectations. This issue indicates the need for a performance measurement approach that can take the efficiency concept into account. Another important concept that is not investigated in the current road maintenance performance measurement systems is the effect of the environmental factors (e.g., climate, location, and etc.) and operational factors (e.g., traffic, load, design-construction adequacy, and etc.) on the performance of the road maintenance process. This issue, again, indicates the need for a performance measurement approach that can take such external and uncontrollable factors into account. The purpose of this research is to develop and implement a comprehensive framework that can measure the relative efficiency of different road maintenance strategies given the (i) multiple inputs and outputs that characterize the road maintenance process and (ii) uncontrollable factors (e.g., climate, traffic, etc.) that affect the performance of such process. It is challenging to measure the overall efficiency of a process when such process is a multiple input-multiple output process and when such process is affected by multiple factors. To address this challenge, an innovative approach to efficiency measurement, Data Envelopment Analysis, is used in this research. It is believed that this research, by taking the efficiency concept into account, will significantly improve the ways that are currently used to model and measure the performance of road maintenance. The findings of this research will contribute new knowledge to the asset management field in the road maintenance domain by providing a framework that is able to differentiate effective and efficient maintenance strategies from effective and inefficient ones.

Da diversi anni la letteratura economica raccomanda l'utilizzo del road pricing come strumento efficiente per internalizzare le esternalità (ambientali e di congestione) prodotte dalla circolazione dei veicoli sulle strade. Tuttavia, l'accettabilità di questo strumento è in genere molto bassa. Pertanto, il lavoro di ricerca svolto è stato indirizzato allo studio di uno schema di road pricing più accettabile, giungendo alla elaborazione di una politica innovativa, il charge-subsidy road pricing (CSRP). Il CSRP prevede che gli automobilisti ricevano gratuitamente un certo numero di permessi che consente loro di guidare in un'area soggetta a pricing nelle ore in cui è in richiesto il pagamento. Inoltre, il CSRP consente a coloro che hanno bisogno di un numero maggiore di permessi di comprarne di aggiuntivi dentro pagamento di una charge; allo stesso tempo lo schema prevede che coloro che riescono a risparmiare parte dei permessi ricevuti possano restituirli e ottenere in cambio un beneficio (monetario/fiscale o in natura ) dall'amministrazione incaricata di gestire il sistema. L'idea di fondo che sta dietro il CSRP è il fatto che la distribuzione gratuita di un certo numero di permessi dovrebbe rendere il CSRP più accettabile di altre politiche di road pricing più tradizionali: il lavoro svolto testa questa ipotesi sia da un punto di vista teorico che empirico.

Economists tend to support road pricing for its efficiency properties in tackling road usage externalities (in particular, congestion and environmental impacts), but usually the acceptability of this instrument is really low both among the general public and politicians. Thus, this PhD research is an attempt to design and analyse a more acceptable road pricing scheme, i.e. a charge-subsidy road pricing scheme (CSRP) where car owners are allotted an amount of free units they can use in place of money to pay for the kind of road pricing scheme implemented. Under the CSRP those who want to drive more than the allowance provided are required to pay a charge, while a (monetary/fiscal or in kind) subsidy might be given to those who manage to spare some of the initially distributed rights. The presence of an initial amount of free units should make the CSRP more acceptable than other traditional road pricing schemes: indeed this work investigates this hypothesis by means of a theoretical and an empirical analysis.

▼ Non-road mobile machinery is used for a range of different operations with varying engine load characteristics. Fuel consumption and emission amounts from such machinery are dependent on the operation performed. The engine load during many of the operations performed is largely transient in nature. However, the majority of fuel consumption and emission data reported in the literature are based on static measurements and engine load patterns not representative of the real use of the vehicle. Emission data derived from the average annual use of agricultural tractors, based on three different typical areas of use, were compared with emission data obtained from European and international standards. The results showed that the emission amounts obtained from the engine load cycles stipulated in European and international emissions regulations were not representative of the real use of non-road mobile machinery. Furthermore, operations can be performed using a variety of different approaches depending on factors such as vehicle characteristics and driver behaviour. An engine load simulation model was developed and the results from the simulations showed that by using different driving strategies or transmission characteristics, it was possible to affect the emissions for a specific operation without affecting the fuel consumption or duration of the operation. Changes in engine speed and torque, i.e. transients, are likely to affect the fuel consumption and formation of emissions due to periods of time lags in e.g. the fuel injection system or the boost pressure. During normal operations a decrease in the fuel efficiency due to transient loads was detected. The fuel consumption increased with up to 13% compared with the corresponding steady-state condition. In order to study the effects of transients, special transient test cycles were developed. At high transients, both in engine speed and torque, the effects on fuel consumption and emissions were substantial. For example emissions of particulate matter increased with up to twelve times. Based on these results, a mathematical model was developed that could derive transient fuel consumption and emission amounts for all types of operations using a limited amount of emission measurements.

▼ This dissertation aims to provide another way to evaluate traffic congestion's impacts on regional economy besides of traditional method of calculating congestion costs in terms of traffic delay and wasted fuel which has encountered considerable critiques on debatable definition and measurement of both benchmark speed and value of time. To additionally measure traffic congestion's indirect and long-term influences, an econometric approach is applied in this study. Since traffic congestion should be considered as a factor that may affect the efficiency of production procedure rather than a direct input in production function, a two-step approach is implemented here. Initially, a Translog production function model with three inputs is applied to calculate the Total Factor Productivity (TFP) growth. Sequentially, regression analysis is conducted to detect traffic congestion's impacts on TFP growth. To comprehensively investigate congestion's influences, a stochastic frontier analysis is further introduced to decompose the TFP growth into technical change, scale efficiency change and technical efficiency change. The relationship between traffic congestion and each component of TFP growth is then probed into. To verify the results from the parametric analysis, a non-parametric analysis is also applied in this dissertation. The Malmquist productivity index as well as its components is calculated using the Data Envelopment Analysis (DEA), and then each of them is regressed based on the same information applied in the parametric analysis. Results derived from both methodologies are compared at the end. The data covers 31 large and very large American urban areas, boundaries of which are defined by the author using ArcGIS software, during the period from 1990 to 2009. Influenced by the conversion from SIC to NAICS in later 1990s, in order to keep data's consistency, the research periods is divided into two segments: 1990-2000 and 2001-2009, which also provides an opportunity to make comparisons between these two periods. After considering various econometric and statistical issues, such as stationarity, spatiality, multi-collinearity, heteroscedasticity, auto-correlation, cross-sectional dependence, and endogeneity, a SYS-GMM (System General Moment Methodology) is implemented and corresponding results show that traffic congestion has significantly negative impacts on TFP growth during 1990 and 2000, while this impact becomes positive and still significant in the successive period. Moreover, congestion didn't affect technical change significantly in both periods. Its impact on technical efficiency change became trivial after 2000, though it negatively influenced this component in the previous period. For scale efficiency change, traffic congestion seems like a positive contribution continuously. Both parametric and non-parametric analysis provide similar results, though still tiny differences exist. Three possible explanations are provided correspondingly: (1) adaptation and adjustment to congestion in a long run; (2)… Advisors/Committee Members: Button, Kenneth (advisor).

▼ Two challenging problems facing our world are the exhaustion of fossil fuels and climate change. Microalgae are eukaryotic phototrophs or prokaryotic cyanobacteria (blue green algae) that are able to capture CO2 and produce lipids suitable for biodiesel, thus can mitigate these challenges. The potential application of microalgae biomass for biofuel production is a clean and sustainable approach to replace fossil fuels. An important consideration for reducing the cost of biofuel is the economical production of algal biomass with high lipid yields. In this study, the marine microalgae Nannochloropsis gaditana were investigated for biomass and lipid production using two wastewater streams, i.e., road salt run-off and vegetable Greenhouse industry effluents as the growth media using batch or fed-batch cultivation. The recovery of biomass was also investigated using coagulants or pH change. In the first phase of the research the effect of salinity on biomass concentration and lipid production was examined in the batch cultures. Increasing the concentration of salt in the nutrient road salt growth media increased the lipid content from 17% to 21.6% (w/w dry weight) which had the 70%(w/w) of long chain fatty acid, which are suitable for the biofuel production. The fed-batch cultivation system was next applied to provide the nutrition sufficient, depletion and repletion conditions. Three different feeding strategies were examined: continuous, pulse and stage feeding for the effect on biomass and lipid yields. The best condition of the feeding regime was identified as pulse feeding based on the substrate to biomass conversion and lipid yield, which resulted the biomass of 2.08+/-0.03g. The increased light intensity doubled the lipid yields with the maximum of 58% (w/w) lipid content and the lipid productivity of 47mg/L/day was obtained. The final phase of the study evaluated the flocculation methods to harvest the biomass from the growth media using two approaches: coagulant chemical addition and pH change. The pH values of 11-threshold pH for the alkaline flocculation of cells above, which the cells flocculate at the faster rate and the harvesting efficiencies over 90%, were achieved. The harvesting efficiency of 95% was achieved with ferric chloride with concentration factor of 23.5. The bio-coagulant chitosan was not effective to coagulate the cells.

Most transportation problems arise from individual travel decisions. In response, transportation researchers had been studying individual travel behavior – a growing trend that requires activity data at individual level. Global positioning systems (GPS) and geographical information systems (GIS) have been used to capture and process individual activity data, from determining activity locations to mapping routes to these locations. Potential applications of GPS data seem limitless but our tools and methods to make these data usable lags behind. In response to this need, this dissertation presents a GIS-based toolkit to automatically extract activity episodes from GPS data and derive information related to these episodes from additional data (e.g., road network, land use). The major emphasis of this dissertation is the development of a toolkit for extracting information associated with movements of individuals from GPS data. To be effective, the toolkit has been developed around three design principles: transferability, modularity, and scalability. Two substantive chapters focus on selected components of the toolkit (map-matching, mode detection); another for the entire toolkit. Final substantive chapter demonstrates the toolkit’s potential by comparing route choice models of work and shop trips using inputs generated by the toolkit. There are several tools and methods that capitalize on GPS data, developed within different problem domains. This dissertation contributes to that repository of tools and methods by presenting a suite of tools that can extract all possible information that can be derived from GPS data. Unlike existing tools cited in the transportation literature, the toolkit has been designed to be complete (covers preprocessing up to extracting route attributes), and can work with GPS data alone or in combination with additional data. Moreover, this dissertation contributes to our understanding of route choice decisions for work and shop trips by looking into the combined effects of route attributes and individual characteristics.

▼ Considering the recent increase in the use of fiber reinforced polymers in the civil engineering industry in general and in the bridge engineering industry in particular, as well as the recently more and more applied cylindrical truss bridge type, this research focuses on the question whether it is possible to combine fiber reinforced polymers as stand-alone structural material and this bridge type to construct a bridge suitable for heavy traffic as well as bicycle and pedestrian traffic. This research combines an extensive literature study on the use of fiber reinforced polymers for bridge engineering with a theoretical feasibility- and design-study on fiber reinforced polymer cylindrical truss bridges for heavy traffic. During the design study the spatial needs of all bridge users were defined to obtain an initial shape of the bridge. This shape was then optimized in several steps using finite-element-modeling and -analysis, yielding a final shape of the bridge. The behavior of this structure under design loads was then extensively investigated, again using finite element analysis, showing that the bridge could very well meet the self-derived deflection limit for fiber reinforced polymers at relatively low stress levels. Since fiber reinforced materials are a very diverse field of material, with hundreds of different compositions being available, the first result of this study was the choice of a suitable composite for further analysis. For this bridge design very high fiber content (>60%) carbon/epoxy composite was used. The main reason for this choice was the high modulus and -strength of the carbon fibers and the high durability and strength of the epoxy resin. A major reason of the slow implementation of fiber reinforced polymers in the bridge engineering industry are the worries concerning the lack of fire safety of the material. The literature study of this research showed however that it is possible to construct a heavy traffic full-FRP truss bridge, while complying with the known fire safety standards. The virgin FRP material can be adapted by several fire-protection measures; it turned out that a combination of intumescent gel-coating and low volume phosphorous filler systems works best in increasing the fire resistance and thereby providing a fire resistance class of R30 for hydrocarbon fire curve loading. The initial shape of the bridge was optimized in three stages: first several different truss topologies, which were derived with a parametric geometric model, were analyzed and compared using finite element analysis software, yielding the square truss with one diagonal as most efficient topology. In the next steps several grid sizes of this truss as well as several cross section dimensions were compared, again using finite element analysis software. An optimum was found between minimum material usage and minimum deflection, which reduced the material usage of the main load bearing elliptical truss by about 40% compared to the initial variant. The optimized structure was then fitted with the inner bridge… Advisors/Committee Members: Bijlaard, F.S.K. (mentor), Kolstein, M.H. (mentor), De Boer, A. (mentor), Hendriks, M.A.N. (mentor).
