▼ In the passing decades, the monitoring of pavements and passing vehicles was developed vigorously with the growth of information and sensing technology. Pavement monitoring is an essential part of pavement research and plays an important role in transportation system. At the same time, the monitoring system about the traffic, such as Weigh-in-Motion (WIM) system and traffic classification system, also attracted lots of attention because of their importance in traffic statistics and management. The monitoring system in this dissertation combines the monitoring for pavements and traffic together with the same sensing network. For pavement health monitoring purpose, the modulus of the asphalt layer can be back-calculated based on the collected mechanical responses under corresponding environmental conditions. At the same time, the actually strain and stress in pavements induced by each passing vehicle are also used for pavement distress prediction. For traffic monitoring purpose, the horizontal strain traces are analyzed with a Gaussian model to estimate the speed, wandering position, weight and classification of each passing vehicle. The whole system, including the sensing network and corresponding analysis method, can monitor the pavement and the traffic simultaneously, and is called transportation monitoring system. This system has a high efficiency because of its low cost and easy installation; multi-functionality to provide many important information of transportation system. Many related studies were made to improve the prototyped transportation monitoring system. With the assistance of numerical simulation software ABAQUS and 3D-Move, the effect of many loading and environmental conditions, including temperature, vehicle speed, tire configuration and inflation pressure, are taken into consideration. A method was set up to integrate data points from many tests of similar environmental and loading conditions based on Gaussian model. Another method for consistent comparison of variable field sensor data was developed. It was demonstrated that variation in field measurement was due to uncontrollable environmental and loading factors, which may be accounted for by using laboratory test and numerical simulation based corrections.

▼ This study attempts to explore empirically how gross vehicle weight (GVW) will affecttraffic flow characteristics in both free-flow and vehicle following situations. The successof the study is highly dependent on the empirical data provided by the traffic datacollectionsystem.Currently, many kinds of systems or devices are available which measure or monitor orenforce traffic dedicatedly. The use of these dedicated or nonintegrated systems ordevices in traffic data-collection or monitoring and traffic enforcement is useful in certainapplication, especially when only dedicated parameter is considered.However, these devices may have limited measurement capabilities and unsuitable forthis study, where the devices are incapable of simultaneously measuring all essentialtraffic and vehicle parameters such as speed, headway as well as weight in real-time. Theuse of these dedicated devices for this study will result in data inconsistency andincomprehensive measurable traffic parameters.Thus, a comprehensive and continuous traffic data-collection system based on weigh-inmotiontechnology has been developed and installed at one of the federal roads inMalaysia for study purposes. The developed system is capable of simultaneously andcontinuously measuring large sample and all essential traffic and vehicle parameters inreal-time. It also uses the minimum number of sensors necessary to provide the maximumnumber of various traffic and vehicle parameters.Statistical analysis was then performed to the collected data to quantify that the grossvehicle weight can have a significant effect in traffic flow characteristics in both freeflow and following situations. The results lead to explore the driver behavior incontrolling the vehicle from two different perspective: driver’s visual input and vehicledynamics capability.The first empirical analysis results showed that statistically for each type of heavy vehicle,there was a significant relationship between free flow speed of a heavy vehicle and itsGVW. Specifically, the results suggest that the mean and variance of free flow speeddecrease with an increase GVW by the amount unrelated to size and shape for all GVWrange. Then, based on the 85th percentile principle, this study proposed a new concept forsetting differential speed limit for heavy vehicle by incorporating GVW where a differentspeed limit is imposed to the heavy vehicle according to its GVW.The second empirical analysis results showed that how GVW of following vehicle andsize of leading vehicle will affect the driver behavior in controlling their speed underdifferent compositions of leader-follower pairs in a car-following situation. The mainfindings of this study are when we incorporate the vehicle dynamic’s capability in a carfollowingsituation, the GVW of following vehicle and the size of leading vehicle weresignificant sources of variation in following vehicle speed and relative speed, and theirinteraction influence the driver behavior in controlling the speed.The third study investigated empirically how different composition…

▼ Transportation by trucks plays a major role in North America’s economy. The growth of this industry will increase the loads on existing roads and highways and raises the possibility of overloaded vehicles, which causes significant damage to the pavement and consequently will reduce the lifespan of the roads. Weigh-in-motion (WIM) systems technology helps to address the challenge of overloaded vehicles. This technology provides traffic monitoring, collects data for pavement research and design, and improves the capacity of static weigh station operations. However, there is still a lack of knowledge about the behaviour of WIM sensors installed in different environments, which affects reliable and precise data gathering. More knowledge is required on proper installation procedures, pavement design for WIM systems, choice of sensor type for location, and calibration processes. This research is intended to explore the behaviour of WIM piezoelectric sensors under different loads and environmental conditions. Specifically, the effects of air and pavement temperature, and weight and speed of trucks are examined with respect to the estimation accuracy of WIM sensors. To accomplish this, three WIM systems composed of different piezoelectric transducers were installed at the CPATT test site at the Waste Management facility of the Region of Waterloo in 2007, and two WIM systems were installed between exits 238 and 250 on Highway 401 eastbound near Woodstock, Ontario. It was concluded that the output of the polymer piezoelectric sensor is influenced by temperature and weight factors but not by normally observed vehicle speed differences. While temperature can be compensated for, not enough information has been gathered yet does the same for weight factor. It should be noted that very low speeds (e.g. < 50 km/hr) result in significant errors for all the sensors, so that in congested sections WIM results should be interpreted accordingly. These results will be useful for investigating the effects of environmental conditions on other WIM systems and for predicting the responses of sensors in actual installation environments. This will assist in the recommendation of: (1) alternative and transparent calibration procedures for the WIM sensor systems, (2) and improved benefits of least expensive technology.

▼ Weigh-in-Motion (WIM) systems have improved the process of collecting data from heavy vehicles on the U.S. highway system and enforcing the laws that govern vehicle weights. The benefits of WIM are reaped by everyone from highway designers and voernments officials, to truck drivers and transportation industry owners. The data collected by WIM devices is essential for proper pavement design, developing pavement management systems, weight enforcement strategies, modeling traffic improvement projects, and predicting load-related distresses and performance. While WIM offers many advantages over its alternative, static weighing, the technology is limited by problems associated with the accuracy of its measurements. Weigh-in-Motion systems that lack accuracy require vehicles to travel slower and can result in higher queues, longer delays, and potential hazards. For these reasons, WIM system performance must be improved in order to adequately serve its purpose. In order to evaluate WIM system performance and determine what vehicle characteristics have the most affect on it, two systems in the Commonwealth of Virginia were evaluated. The first system was an in-service WIM system at the Troutsville weigh station on I-81. The Troutsville station had bending plate WIM scales located in both the northbound and southbound directions. The second system in a newly developed WIM system manufactured by Omni Weight Corporation (OWC) and was installed at the Virginia Smart Road for evaluation. The OWC scale is a completely sealed and buried system that has ten strain gauge sensors in its interior. Evaluation of both scales was performed by conducting a number of test runs under varying load conditions. Testing at Troutsville was performed using four different test vehicles with multiple loads on each. Variation in load was achieved by loading the test vehicles with various numbers of concrete Jersey Walls. Testing on the OWC scale was performed using only two test vehicles while varying the speed, load, tire pressure, and direction of travel over the scale. The study showed that the scales at the Troutsville weigh station yielded 10% error or less on only 77% of the tests, not complying with the required 95% set forth by ASTM E-1318. In comparison, using the manufacturer's processed data for the OWC scale yielded only 18% of its tests with 10% error or less, far below the ASTM standard. A model was developed to re-calculate the axle weights using the raw sensor data from the OWC scale; and an evaluation of the accuracy of this data showed that the OWC scale performed much better. While compliance with the ASTM standards was still not achieved, it rose from 18% to 71% of the tests having 10% error or less. Repeatability of the Troutsville scales and OWC scales was found to be comparable. Advisors/Committee Members: Al-Qadi, Imadeddin L.

Nas últimas décadas os pavimentos rodoviários brasileiros têm tido seu desempenho comprometido devido a uma série de fatores, entre eles incluem-se não somente o crescente aumento do volume de tráfego de veículos pesados e aumento de sua capacidade de transporte, mas principalmente a circulação com cargas acima dos limites legais estabelecidos, configurando uma situação crítica para a sua adequada durabilidade da estrutura projetada. Paralelamente aos investimentos necessários, é importante também o desenvolvimento de métodos mais racionais de dimensionamento de pavimentos contemplando as especificidades dos materiais empregados e levando em consideração as condições climáticas e, principalmente uma completa e detalhada caracterização do tráfego solicitante. Neste contexto apresentado, a pesquisa insere-se em dois importantes estudos. O acompanhamento construtivo e monitoramento sistemático de desempenho de dois trechos na rodovia BR-448/RS e a continuidade do monitoramento de outros dois na BR-290/RS, trecho em concessão entre Osório e Porto Alegre (Freeway). Estas atividades inserem-se no “Projeto Integrado da Rede Temática de Tecnologia em Asfalto Petrobras/ANP", de abrangência nacional, para desenvolvimento de um novo método brasileiro de dimensionamento de pavimentos O segundo estudo trata-se de um completo monitoramento de cargas na Freeway, através da instalação e operacionalização inédita de um equipamento de pesagem dinâmica de alta velocidade (Hight Speed Weigh-in-Motion – HS-WIM) para determinação do espectro de cargas e posterior análise de sua influência no desempenho de pavimentos. Com ambos os estudos foi possível, além de determinar o espectro de cargas, os carregamentos médios e os níveis de sobrecargas praticados naquela rodovia, verificar como estas cargas influenciam o desempenho do pavimento e confrontar estes dados com as tendências observadas através do monitoramento sistemático dos trechos analisados. Por meio do desenvolvimento do presente trabalho pretende-se contribuir para melhorias na engenharia rodoviária e de tráfego através da inserção de novas tecnologias de monitoramento e fiscalização das cargas transportadas e contribuir com o desenvolvimento de um novo método de dimensionamento de pavimentos flexíveis proposto pela Rede Temática de Asfalto, através do levantamento de dados nos trechos experimentais para desenvolvimento de modelos de desempenho e sua posterior inserção nos modelos de calibração.

In recent decades the Brazilian road pavements have had their performance reduced due to a number of factors, not only the increasing volume of heavy vehicles and increased transport capacity, but mainly the flow with loads above the established legal limits, setting a critical situation for the durability of the designed structure. Alongside the necessary investment, it is also important to the development of more rational methods of pavement design, considering the specificities of the materials used and taking into account the climatic conditions and a complete and detailed…

▼ Government stakeholders rely upon traffic information such as the weight of trucks on the roadways to provide and maintain safe and reliable highway/bridge infrastructure. Bridge weigh-in-motion (BWIM) provides an alternative to conventional static weigh stations for obtaining vehicle axle weights. Traditional BWIM algorithms are capable of predicting the axle weights of vehicles traveling at constant speed across a bridge with known influence line, but they often lose accuracy when measuring vehicles are traveling at nonconstant speed. This thesis presents a methodology to improve BWIM accuracy when measuring a vehicle traveling at nonconstant speed by transforming variable speed response data to constant speed data. A BWIM package capable of determining vehicle speed and axle spacing, calculating the influence lines of a bridge, and predicting the axle weights of a vehicle crossing the bridge is developed in MATLAB. A numerical study is performed using finite element analysis in MATLAB to evaluate the performance of the BWIM package when measuring loads traveling at constant speed and variable speed. The results of the numerical study show the speed correction is able to improve BWIM accuracy for a variable speed vehicle to nearly the accuracy level of a constant speed vehicle. A field study is also performed. A vehicle with known weight was used as a calibration vehicle to measure the influence line of a bridge on the University of Alabama campus. A different vehicle was then driven across at constant speed, then again at variable speed to generate data for various study cases. Results of the field study showed that correcting variable speed response data can significantly improve the accuracy of axle weight predictions, but more research is required to reach the accuracy level BWIM is able to achieve when measuring constant speed vehicles.

▼ At hundreds of Weigh in Motion (WIM) stations, State Departments of Transportation collect traffic data every year to support pavement design, to enforce weight restrictions on highways and bridges, and to provide planning data for highway improvements. Reliable WIM data is particularly important to support the procedures in the FHWA Mechanistic Empirical Pavement Design Guide (MEPDG). The purpose of the research is to identify and resolve four related but relatively stand-alone problems associated with WIM data collected by NCDOT. Quality Control: After the NCDOT collects WIM data and converts it from proprietary vendor format to an ASCII text format, the quality of the data must be checked. During the quality control (QC) procedures, tests identify incomplete datasets, out of range values for individual vehicle classes, and other possible data problems. Vehicle class and weight checks generate 0.97% and 6.42% anomalies, respectively thus confirming that NCDOT equipment captured reliable WIM measurements. NC Urban and Rural Truck Traffic Profiles: Knowing the type of traffic by vehicle class by highway functional classification is critical to designing, maintaining and paying for North Carolina highway pavements. Thus, GVW plots by vehicle class and highway functional class are very important. The results indicate that in general, the class 5 and 9 GVW plots for all categories of WIM stations show expected trends. These results may be used by highway planners and pavement designers to quickly determine typical truck traffic profiles in the various NC regions and provide insight into NC truck transportation flows. NC vs. University Of Arkansas WIM QC Analysis: Most highway agencies have the data collection and design groups in different units. While a single software solution is not practical, it is recommended to perform two separate processes where the output of data QC meets the needs and standards of the design process. A comparative analysis between the QC methods followed by the University of Arkansas (UARK) and NCSU/NCDOT shows that while the UARK Pavement Designer software has better mapping functions and supports data analysis and design. However, from a WIM data analystÃ¢â‚¬â„¢s perspective it is a Ã¢â‚¬Å“black boxÃ¢â‚¬Â . In addition there is significant data reduction involved and the rigid nature of an automated QC process does not provide enough justification for the data to be used as input for the MEPDG. On the other hand, the NCSU/NCDOT approach is a two step procedure with a comprehensive QC procedure that provides the flexibility of manual overriding based on local knowledge of WIM stations and a separate unit managing the pavement design element. WIM Data Management and Analysis in SQL Server: While most research topics focus on collection and quality of data with little emphasis on the development of an integrated Database Management System (DBMS) to store and analyze traffic data. An innovative approach to perform quality control procedures and data analysis on two test WIM… Advisors/Committee Members: John Stone, Committee Chair (advisor), William Rasdorf, Committee Member (advisor), Billy Williams, Committee Member (advisor).

▼ The worldwide aging of the infrastructure and the development of new technologies in the construction industry provided a need for structural health monitoring (SHM). SHM provides a tool for owners and researchers to assess the condition of a structure and monitor its behavior under real life conditions. Road transport and the related infrastructures are clearly an integral part of the economic, political, and social development of the western world. As an example, highway bridges as a major part of infrastructures can be greatly damaged by excessively heavy vehicles or severe environmental conditions. It is therefore, important to assure that such facilities are well maintained and function properly in order to avoid major failures or the need for costly repairs. In current thesis, it is attempted to innovate techniques in order to measure the vehicles loads affecting the bridge elements as well as damage detection methods to monitor the defects along the in-service bridge structural components. Bridge Weigh-in-Motion (BWIM) is using an existing bridge to weigh trucks while they are moving at full highway speeds. A new method of BWIM has been established in order to weigh the passing trucks relying on the shear strain measurements near the bridge abutments which differs from the flexural strain based traditional systems. The shear strain are measured using the rosettes sensors installed on the webs of bridge girders to directly measure the individual axle weights of trucks passing over the bridge abutments. Two concrete slab on steel girder bridges, and a box girder prestressed concrete with different structural types, span lengths, and different sizes were instrumented for the performance verification of the proposed BWIM system. A series of truck runs were implemented in the field to calibrate and evaluate the proposed BWIM system’s efficiency. In addition, current research formulated a reference-free distributed damage detection method in order to locate the defects that occur in structures under in-service operating conditions. The sensing method is developed on the basis of Brillouin scattering phenomena. It employs the dynamic distributed strain measurement data in order to sense the structural perturbations under in-service operations, i.e. bridges subjected to traffic loadings, or aircrafts during flights. The advantage of the method developed in this study is that it enables the structure to be monitored at any stage during its service life without the need for prior reference data. An experimental program was designed to investigate the feasibility of the proposed approach in detecting the locations of very small defects. Laboratory experiments were designed in order to simulate the effect of ambient conditions in bridges, especially in terms of realistic displacements, i.e. deflections occurring in highway bridges. In a following effort, a theoretical model was also investigated to analysis the strain transfer mechanism from the structure surface to the distributed optical fiber components in the presence… Advisors/Committee Members: Ansari, Farhad (advisor), Ozevin, Didem (committee member), Stroscio, Michael (committee member), Mahamid, Mustafa (committee member), Karpov, Eduard (committee member).

▼ Initiation and propagation of fatigue cracks under heavy traffic loading is one of the most frequent causes of damage for road steel bridges. A particular case where fatigue phenomena have often been observed is the orthotropic steel deck (OSD). Due to its intricate layout with plated structural components in different planes and the inherent vulnerability of the employed welded connections to fatigue, bridges with this type of deck require accurate fatigue verifications. In the process of fatigue assessment an important part of uncertainty is the fatigue loading, commonly expressed in the form of stress variation at each detail. This stress-time history is typically related to certain bands of amplitude of stress cycles and their corresponding number. Thus, acquisition of relevant information for these aspects becomes important. Since, as representative as possible fatigue assessment is sought, strain measurements are utilised, so that bridge-specific load characteristics can be obtained. It is therefore examined to which extent relevant fatigue load information can be obtained through these monitoring in OSDs. It is further of interest to which extent, based on the identified load attributes, the stress histories at other details can be simulated. For practical investigation of the foregoing a case study is used, where strain measurements at specific locations of an OSD have been conducted. An approach is formulated based on bridge weigh-in-motion (B-WIM); a technique to weigh vehicles as they pass above a bridge. The main principle of B-WIM is the comparison of the measured response with a corresponding theoretical one, based, in this case, on a FE model. The peculiarities of the OSD result in various parameters that can affect the stresses and should be allowed for in the modelled response. The employed approach is structured in such a way so that the influence of these parameters can be examined. Application of the approach results into identification of transverse position and wheel loads. Then, simulated stress derivation at strain gauge locations based on identified characteristics and certain assumptions is realised. Comparison of these stresses with the corresponding measured ones gives an insight on the accuracy of the whole task. Unfortunately, acquired information on loads, transverse positions, wheel types etc. cannot be directly verified due to absence of reference values. Inspection of the comparisons between modelled and measured stresses shows a relatively good agreement in the overall shape, which implies close approximation of the wheel load-transverse position combination. In the vicinity of the sensors located under the deck plate, however, the effect of additional parameters like the wheel footprint increases. A number of factors thus act in a combined way affecting the stress ranges and leading, locally, to higher discrepancies. The discussed influence is further verified by a sensitivity analysis. Generally, it can be concluded that information such wheel loads, approximate transverse… Advisors/Committee Members: Bijlaard, F. (mentor), Kolstein, H. (mentor), Hendriks, M. (mentor).

▼ Traffic is one of the key inputs in pavement design. The pavement Mechanistic-Empirical (ME) design allows three different types of input level of traffic data based on the availability of the data. They are: site specific data (Level 1), regional data (Level 2), and the national data (Level 3). Level 1 inputs (e.g., load magnitude, configuration, and frequency) are generated from Weigh-in-Motion (WIM) station installed in each site. However, it is not always practically possible to install WIM station due to high cost of WIMs. Therefore, often time the designers have to rely on the Level 2 or Level 3 traffic data. But it is not known yet how good the national data or the regional data compared to New Mexico's site specific data in predicting interstate pavement performances. To this end, this study examines the effects of different levels of traffic inputs on predicted pavement distresses in New Mexico. Two major interstate highways were considered in this study: Interstate-40 (I-40) and Interstate-25 (I-25). Site-specific inputs were developed using installed WIM stations at the pavement sites. WIM data was analyzed using an advanced and updated software developed by the UNM researchers. Traffic data were simulated through the ME design software for predicting pavement performances. Results show that axle load spectra (ALS) and lane distribution have a great influence on predicted interstate pavement performance. Vehicle class distribution (VCD), directional distribution, and standard deviation of lateral wander have a moderate impact on pavement performance. Monthly adjustment factor, axles per vehicle, axle spacing, and operational speed have very little effect on the predicted pavement performance. On the other hand, predicted pavement performance is insensitive to hourly distribution and wheelbase distribution. Hence, regional traffic data were developed from ten site specific data using both arithmetic average and clustering methods. Since, ALS and VCD are two inputs which affect the predicted distresses significantly, these two values were considered for this case. Finally, using the regional inputs, the national inputs, and the site-specific inputs of VCD and ALS, pavement ME predicted performances were determined. Results show that predicted performance by the cluster data are much closer to those by the site-specific data. Performance generated by the ME default values are significantly different from those generated by the site-specific or cluster values. When comparing performance by the ME design default to those by the statewide average data, the ME design default VCD produces less error than the ALS. Therefore, this study recommends using clustered data or site-specific WIM data instead of ME default or statewide average value. In addition, a guideline was successfully established to select appropriate axle load spectra inputs based on vehicle class data.

▼ Truck traffic is a crucial factor that contributes to pavement damage. The urbanization and globalization promote the higher level of daily consumption for goods, thus increasing the derived demand for freight transport. In some countries, such as Australia, there is a trend towards using larger vehicles, which raised the road authorities’ concern about their effect on pavement because of the lack of pavement maintenance and rehabilitation funding. Therefore, it is important to have a comprehensive understanding of Australian road freight market and optimize the allocation of freight for different types of trucks to reduce the total pavement damage. Weigh-in-motion (WIM) system, which measures and records detailed vehicle information operating on road, was the data source for this study. The data was provided by the State Road Authority of Victoria (VicRoads). This thesis gave out a prototype filtering strategy for WIM database to improve the accuracy. Also, it investigated the efficiency of freight transport by comparing the effect of six-axle semi-trailers and nine-axle B-doubles with regards to pavement performance when carrying various payloads. Mathematical models were developed to help decision makers consider how to distribute the road freight task more efficiently to minimize the pavement damage induced by freight vehicles. A simplified pavement performance prediction model was utilized as a basis to determine the future pavement maintenance & rehabilitation schedules and thus, help compare the long-term pavement treatment costs for different traffic loading scenarios. The outcomes of the research showed that it would have considerable advantages in reducing the overall pavement damage by decreasing the percentage of empty trucks, changing the proportion of freight carried by B-doubles as well as optimizing the payload distributions. In addition, there would be significant benefits in the pavement maintenance & rehabilitation costs over the pavement service life by improving the allocation of freight for trucks.

▼ This project evaluates the performance of Weigh-in-Motion (WIM) auto-calibration methods used by the Arkansas Department of Transportation (ARDOT). Typical auto-calibration algorithms compare the WIM measured weights of vehicles from the traffic stream to reference values, using five-axle tractor-trailer configured trucks for comparisons, e.g. Federal Highway Administration (FHWA) Class 9. Parameters of the existing algorithms including the Front Axle Weight (FAW) reference value, the sampling frequency required to update the calibration factor, and thresholds for Gross Vehicle Weight (GVW) bins were evaluated. The primary metric used to estimate algorithm performance was Mean Absolute Percent Error (MAPE) between the WIM and static scale GVW measurements. Two altered auto-calibration algorithms based on methodologies utilized by ARDOT and the Minnesota DOT (MNDOT) were developed. Parameters for the algorithms are based on combinations that produced minimal MAPE at the study sites. WIM data from two sites (Lamar and Lonoke) and static scale data from one site (Alma) were collected along Eastbound I-40 in Arkansas during March 2018. The updated MNDOT auto-calibration algorithm reduced the MAPE by 2.5% compared to the baseline method at the Lamar site (n = 77 trucks) and by 1.1% for the Lonoke site (n = 44 trucks). The updated ARDOT algorithm reduced MAPE by 1.6% at the Lamar site and 0.6% at the Lonoke. Due to limitations of the field data collection methodology, the thresholds defining FAW reference values and the FAW reference values themselves were not able to be tested for spatial transferability, e.g. the samples of trucks at the Lonoke WIM site were a subsample of the trucks at the Lamar WIM site. Improvements in auto-calibration accuracy at low volume sites but was not tested due to the small number of confirmed vehicle matches at a third WIM site (Bald Knob, n = 2 trucks). Overall, site specific tuning of auto-calibration algorithms will improve the accuracy of WIM data which is used for pavement design, maintenance programming, and traffic forecasting. For example, improvements of 2.5% MAPE of WIM measured GVW results in a 39% difference in the estimated Equivalent Single Axle Load (ESAL) factors used for pavement design.

▼ Weigh-in-Motion (WIM) sensors are installed on mainline lanes at highway locations to record vehicle weights, axle spacing, vehicle class, travel speed, vehicle length, and traffic volume. These data elements support effective transportation planning, infrastructure design, and policy development. Therefore, it is important that WIM sensors supply accurate data. After initial installation and calibration, WIM systems may experience measurement drifts in weight and axle detection. Recalibration takes two general forms: (a) On-site calibration involving running trucks of known weight over WIM scales and (b) Auto-calibration methods involving comparisons to assumed reference weights. Auto-calibration can be more cost and time effective than on-site calibration. This paper leverages the increasing prevalence of truck tracking technologies like Global Positioning Systems (GPS) to improve auto-calibration methods and was divided into three aims: (i) data collection, (ii) data processing and (iii) model development. Truck GPS data from a national provider, WIM recorded truck weights, and static weights collected at weight enforcement station were gathered at several highway locations in Arkansas. A “matching” algorithm was developed to automatically match each GPS record to a WIM record based on timestamp and vehicle configuration. Algorithm performance was assessed via manual video verification of matches. Approximately, 75% of WIM and truck GPS records were correctly paired. Lastly, an auto-calibration model was developed to estimate lane and site specific calibration factors. The algorithm estimates hourly calibration factors by comparing the front axle weight of the same truck as it passes multiple WIM sites. Algorithm performance was measured by comparing estimated front axle and gross vehicle weights to known weights of the same truck measured at a static enforcement scale. The algorithm achieved Median Absolute Percent Error (MdAPE) of 11-23% for front axle weight and 15-45% for gross vehicle weight. These results can be improved by increasing the number of trucks that are able to be tracked across WIM sites with Automatic Vehicle Identification.

▼ In the past, transportation related economic analysis has considered agency related costs only. However, transportation managers are moving towards more holistic economic analysis including road user and environmental costs and benefits. In particular, transportation air pollution is causing increasing harm to health and the environment. Transport managers are now considering related emissions in transport economical analyses, and have established strategies to help meet Kyoto Protocol targets, which specified a fifteen percent reduction in Canada's emissions related to 1990 levels within 2008-2012.The objectives of this research are to model heavy vehicle emissions using a emissions computer model which is able to assess various transport applications, and help improve holistic economic transport modeling. Two case studies were evaluated with the model developed.Firstly, the environmental benefits of deploying weigh-in-motion systems at weigh stations to pre-sort heavy vehicles and reduce delays were assessed. The second case study evaluates alternative truck sizes and road upgrades within short heavy oilfield haul in Western Canada. The model developed herein employed a deterministic framework from a sensitivity analysis across independent variables, which identified the most sensitive variables to primary field state conditions. The variables found to be significant included idling time for the weigh-in-motion case study, road stiffness and road grades for the short heavy haul oilfield case study.According to this research, employing WIM at weigh stations would reduce annual Canadian transportation CO2 emissions by nearly 228 kilo tonnes, or 1.04 percent of the Canadian Kyoto Protocol targets. Regarding direct fuel savings, WIM would save from 90 to 190 million litres of fuel annually, or between 59 and 190 million of direct operating costs.Regarding the short heavy oil haul case study, increasing allowable heavy vehicle sizes while upgrading roads could decrease the annual emissions, the fuel consumption, and their associated costs by an average of 68 percent. Therefore, this could reduce each rural Saskatchewan municipality's annual CO2 emissions from 13 to 26.7-kilo tonnes, which translates to 0.06 and 0.12 percent of the Canadian Kyoto Protocol targets or between 544,000 and 1.1 million annually. Based on these results, the model demonstrates its functionality, and was successfully applied to two typical transportation field state applications. The model generated emissions savings results that appear to be realistic, in terms of potential Kyoto targets, as well as users cost reductions and fuel savings.

▼ Transportation agencies tasked with forecasting freight movements, creating and evaluating policy to mitigate transportation impacts on infrastructure and air quality, and furnishing the data necessary for performance driven investment depend on quality, detailed, and ubiquitous vehicle data. Unfortunately, commercial vehicle data is either missing or expensive to obtain from current resources. To overcome the drawbacks of existing commercial vehicle data collection tools and leverage the already heavy investments into existing sensor systems, a novel approach of integrating two existing data collection devices to gather high resolution truck data - Weigh-in-motion (WIM) systems and advanced inductive loop detectors (ILD) is developed in this dissertation. Each source provides a unique data set that when combined produces a synergistic data source that is particularly useful for truck body class modeling. Modelling truck body class, rather than axle configuration, provides more detailed depictions of commodity and industry level truck movements. Since body class is closely linked to commodity carried, drive and duty cycle, and other operating characteristics, it is inherently useful for each of the above mentioned applications. In this work the physical integration including hardware and data collection procedures undertaken to develop a series of truck body class models is presented. Approximately 35,000 samples consisting of photo, WIM, and ILD signature data were collected and processed representing a significant achievement over previous ILD signature models which were limited to around 1,500 commercial vehicle records. Three families of models were developed, each depicting an increasing level of input data and output class resolution. The first uses WIM data to estimate body class volumes of five semi-trailer body types and individual predictions of two tractor body classes for vehicles with five axle tractor trailer configurations. The trailer model produces volume errors of less than 10% while the tractor model resulted in a correct classification rate (CCR) of 92.7%. The second model uses ILD signatures to predict 47 vehicle body classes using a multiple classifier system (MCS) approach coupled with the Synthetic Minority Oversampling Technique (SMOTE) for preprocessing the training data samples. Tests show the model achieved CCR higher than 70% for 34 of the body classes. The third and most complex model combines WIM and ILD signatures using to produce 63 body class designations, 52 with CCR greater than 70%. To highlight the contributions of this work, several applications using body class data derived from the third model are presented including a time of day analysis, average payload estimation, and gross vehicle weight distribution estimation.

▼ Overweight vehicle enforcement is a continuous problem for all state Departments of Transportation. Various technologies are in use across the US to aid in the enforcement of vehicle weight limits. However, to date, no technology has been shown to be a definitive solution. The various technologies currently available were researched and the pros and cons of each highlighted. Focus was placed on Bridge Weigh-in-Motion (B-WIM) and an extensive literature review has been conducted following all developments in the field of B-WIM since 1979. The advantages of B-WIM include its ease of installation, portability and potential for high accuracy vehicle weight measurements. Accuracy however is site specific, which makes the selection of a bridge an extremely important element in the success of a B-WIM installation. A bridge selection tool prototype was developed using ArcGIS. The tool was designed to select bridges with the physical characteristics associated with achieving high B-WIM weight measurement accuracies. Daily truck volumes and current Weigh-in-Motion (WIM) sites were also included in the tool to allow for an effective choice of route for installation. As the systems use cellular data signals to transfer data to the weigh crew during the pre-selection process, cell service maps were also included in the tool. The prototype showed that such a tool is feasible and should be beneficial for ALDOT. ALDOT owns two B-WIM systems which it intends to use for overweight vehicle enforcement. An accuracy test of the system was conducted. A bridge in West Alabama was selected for installation. Calibration was conducted and random vehicles were statically weighed to verify the accuracy of the system. A gross vehicle weight accuracy of B (10) was obtained which is more than sufficient for pre-selection of potentially overweight vehicles. Alternative sensor locations and orientations were also investigated and signals were compared. It was found that longitudinal axle detectors located close to the bridge supports provided the cleanest and most distinct signals at the test location. Weighing sensors located at the mid-span provided the best signals for weighing trucks.

▼ In the past few decades, the rapid growth of traffic volume and weight, and the aging of transportation infrastructures have raised serious concerns over transportation safety. Under these circumstances, vehicle overweight enforcement and bridge condition assessment through structural health monitoring (SHM) have become critical to the protection of the safety of the public and transportation infrastructures. The main objectives of this dissertation are to: (1) develop an enhanced bridge weigh-in-motion (BWIM) methodology that can be integrated into the SHM system for overweight enforcement and monitoring traffic loading; (2) present a Bayesian framework to predict the extreme traffic load effects (LEs) of bridges and assess the implication of the growing traffic on bridge safety. Firstly, an enhanced BWIM methodology is developed. A comprehensive review on the BWIM technology is first presented. Then, a novel axle detection method using wavelet transformation of the bridge global response is proposed. Simulation results demonstrate that the proposed axle detection method can accurately identify vehicle axles, except for cases with rough road surface profiles or relatively high measurement noises. Furthermore, a two-dimensional nothing-on-road (NOR) BWIM algorithm that is able to identify the transverse position (TP) and axle weight of vehicles using only weighing sensors is proposed. Results from numerical and experimental studies show that the proposed algorithm can accurately identify the vehicle’s TP under various conditions and significantly improve the identification accuracy of vehicle weight compared with the traditional Moses’s algorithm. Secondly, a Bayesian framework for predicting extreme traffic LEs of bridges is presented. The Bayesian method offers a natural framework for uncertainty quantification in parameter estimation and thus can provide more reliable predictions compared with conventional methods. A framework for bridge condition assessment that utilizes the predicted traffic LEs is proposed and a case study on the condition assessment of an instrumented field bridge is presented to demonstrate the proposed methodology. Moreover, the non-stationary Bayesian method is adopted to predict the maximum traffic LEs during the lifetime of bridges subject to different types of traffic growth and the influence of the traffic growth on the bridge safety is investigated.

▼ This dissertation proposes a system for weighing commercial vehicles in motion using acoustic emission sensors attached to a metal bar placed across the roadway. The signal from the sensors is analyzed by a computer and the vehicle weight is determined by a statistical model which correlates the acoustic emission parameters to the vehicle weight. Such a system would be portable and low-cost, allowing for the measurement of vehicle weights in much the same way commercial tube and radar counters routinely collect vehicle speed and count. The system could be used to collect vehicle speed and count data as well as weight information. Acoustic emissions are naturally occurring elastic waves produced by the rapid release of energy within a material. They are caused by deformation or fracturing of a solid due to thermal or mechanical stress. Acoustic emission sensors have been developed to detect these waves and computer software and hardware have been developed to analyze and provide information about the waveforms. Acoustic emission testing is a common form of nondestructive testing and is used for pressure vessel testing, leak detection, machinery monitoring, structural integrity monitoring, and weld monitoring, among other things (Miller, 1987). For this dissertation, acoustic emission parameters were correlated to the load placed on the metal test bar to determine the feasibility of using a metal test bar to measure the weight of a vehicle in motion. Several experiments were done. First, the concept was tested in a laboratory setting using an experimental apparatus. A concrete cylinder was mounted on a frame and rotated using a motor. The metal test bar was applied directly to the surface of the cylinder and iv acoustic emission sensors were attached to each end of the bar. As the cylinder rotated, a motorcycle tire was pushed up against the cylinder using a scissor jack to simulate different loads. The acoustic emission response in the metal test strip to the motorcycle tire rolling over it was detected by the acoustic emission sensors and analyzed by the computer. Initial examinations of the data showed a correlation between the force of the tire against the cylinder and the energy and count of the acoustic emissions. Subsequent field experiments were performed at a weigh station on I-95 in Flagler County, Florida. The proposed weigh-in-motion system (the metal test bar with attached acoustic emission sensors) was installed just downstream of the existing weigh-in-motion scale at the weigh station. Commercial vehicles were weighed on the weigh station weigh-in-motion scale and acoustic emission data was collected by the experimental system. Test data was collected over several hours on two different days, one in July 2008 and the other in April 2009. Initial examination of the data did not show direct correlation between any acoustic emission parameter and vehicle weight. As a result, a more sophisticated model was developed. Dimensional analysis was used to examine possible relationships between the acoustic… Advisors/Committee Members: Radwan, Essam A..

▼ Structural Health Monitoring (SHM) is a promising tool for condition assessment of bridge structures. SHM of bridges can be performed for different purposes in long or short-term. A few aspects of short- and long-term monitoring of highway bridges are addressed in this research. Without quantifying environmental effects, applying vibration-based damage detection techniques may result in false damage identification. As part of a long-term monitoring project, the effect of temperature on vibrational characteristics of two continuously monitored bridges are studied. Natural frequencies of the structures are identified from ambient vibration data using the Natural Excitation Technique (NExT) along with the Eigen System Realization (ERA) algorithm. Variability of identified natural frequencies is investigated based on statistical properties of identified frequencies. Different statistical models are tested and the most accurate model is selected to remove the effect of temperature from the identified frequencies. After removing temperature effects, different damage cases are simulated on calibrated finite-element models. Comparing the effect of simulated damages on natural frequencies showed what levels of damage could be detected with this method. Evaluating traffic loads can be helpful to different areas including bridge design and assessment, pavement design and maintenance, fatigue analysis, economic studies and enforcement of legal weight limits. In this study, feasibility of using a single-span bridge as a weigh-in-motion tool to quantify the gross vehicle weights (GVW) of trucks is studied. As part of a short-term monitoring project, this bridge was subjected to four sets of high speed, live-load tests. Measured strain data are used to implement bridge weigh-in-motion (B-WIM) algorithms and calculate the corresponding velocities and GVWs. A comparison is made between calculated and static weights, and furthermore, between supposed speeds and estimated speeds of the trucks. Vibration-based techniques that use finite-element (FE) model updating for SHM of bridges are common for infrastructure applications. This study presents the application of both static and dynamic-based FE model updating of a full scale bridge. Both dynamic and live-load testing were conducted on this bridge and vibration, strain, and deflections were measured at different locations. A FE model is calibrated using different error functions. This model could capture both global and local response of the structure and the performance of the updated model is validated with part of the collected measurements that were not included in the calibration process.
