▼ The major goal of this master thesis is to improve truck safety and comfort during lane change manoeuvres. This thesis focuses on the scenario of the driver doing sports exercises inside the cabin when the vehicle is driving automatically on a highway. This topic is one of the foci of the international GlobalDrive project from Technical University of Munich, which aims at sports exercises inside highly automated driving truck cabin by 2030. Using a special chair, drivers are able to do different types of exercises in the cabin. However, the acceleration, deceleration and jerk of normal highly automated vehicles can hardly satisfy the safety and comfort requirements for sports exercises, especially during lane changes. It is very difficult for the driver to keep balance when the lateral or longitudinal jerk and acceleration reach a certain level. In order to provide a suitable environment for exercises, a multi-level control architecture has been designed to satisfy the safety and comfort requirements from an ergonomics aspect. The proposed control scheme will make it easier for the driver to keep balance. Prevention of rollover is included in the architecture, while a Cruise Control (CC)-Adaptive Cruise Control (ACC)-Cooperative Adaptive Cruise Control (CACC) strategy is responsible for the longitudinal safety of the truck. Simulations in realistic and safety-critical scenarios show the effectiveness of the approach.

▼ Models are an important tool for decision making. However, in order to get proper results, these models must be validated and only be used in situations where the conditions of the validation apply. Blind trust on a model can lead to unexpected and inaccurate results. Advancements can be made to reduce the number of situations where this occurs. Not only by making the models more accurate, but also by doing more field studies for validation of behavioural aspects of the traffic. One of these aspects is the process of
lane changing and car following behaviour. These two aspects determine the general longitudinal and lateral driving behaviour. Mathematical models that describe these types of movements for each individual vehicle provide the building blocks for microscopic simulation. In most models, these two aspects are modelled independently, but newer models, such as the integrated driving behaviour model (Toledo, 2003), attempt to mould this into an integral decision structure. This research attempts to validate the
lane changing and car following behaviour of three models: FOSIM, VISSIM and the aforementioned Integrated driving behaviour model. These models are compared against a dataset from TNO of the motorway A270, in situations where free flow conditions apply. The models are tested on the desired speed distribution, the merging point distribution, the accepted gap distributions and the
lane change distribution. The
lane changes that are being found are classified by their distinctive causes, the so-called “triggers”. Six triggers are defined for
lane-
change classification. The main result is that calibration and validation play a major role in the validity of the models. For all tested simulation packages, their default parameters did not reflect the observed data. This means that the driver’s attitude and the traffic conditions have a large impact on the general driver behaviour. In free-flow traffic conditions, Dutch drivers tend to be risk-averse, as reflected in the low number of voluntary
lane changes and the wide gap acceptance distribution. This risk-averseness is usually not part of a model’s default parameter set and therefore calibration is essential to simulate the traffic correctly. Furthermore, the different triggers helped to get a clearer view about what type of
lane changes occur, where, and why they occur. The FOSIM simulation results show that this model has serious limitations. A main point is that this model is too deterministic regarding driver characteristics. Although in theory probabilistic factors could be added to the model, further advancements of the model, such as implementing probabilistic behaviour, requires reprogramming of the simulation package, which was not possible within this research. VISSIM gave better results, but it over-estimates the number of voluntary
lane changes in free flow conditions on Dutch motorways when using the default behavioural parameters. Further calibration of these parameters did partially correct this error, but the remaining estimation errors…

▼ Lane change maneuvers are commonly performed by drivers in highway driving situations. It starts with
the driver planning and making the decision whether a lane change maneuver is necessary according to the
situation. Once the driver decides to do the maneuver, he/she starts to prepare themselves. Next, he/she
changes their lateral position until the vehicle crosses the line between lanes. Finally after crossing the lane
marking, the driver adapts to his/her new positions by stabilizing the vehicle. When lane change maneuvers
are done incorrectly, accidents may happened which can be fatal to those involved in the crash.
Advanced Driver Assistance Systems (ADAS) include several functions that rely on lane change detection
e.g., lane departure warning (LDW) system and lane change assistance system. These functions can be used
to help driver perform a safer lane change maneuver. Having a system which can accurately retrieve and
recognize the driving characteristics of a lane change maneuver will be beneficial for the development of ADAS.
Identifying lane changes in driving data can be done manually by annotations, but it costs a substantial amount
of time and money in case of large driving databases. A cheaper solution would be to use machine learning
algorithms as they excel in this type of problem. Several machine learning algorithms, specifically artificial
neural networks, have been used in many different research applications, including lane change predictions.
This thesis work included several steps. Firstly, driving data was retrieved from UDRIVE, which contains
naturalistic driving data collected from various European countries. The data was processed into segments
containing lane changes and baseline driving. It served as an input for training and testing using a sliding
time window approach. Three neural networks were constructed to identify lane changes. One served as the
baseline model, and the other two were variations of the baseline model called modified Long Short Term
Memory (LSTM) and stacked LSTM, respectively. Training and testing were conducted to these networks
using the same configuration and dataset. During the training process, some of the parameters were adjusted
according to their performance and some could not be adjusted. Parameters that cannot be adjusted are
called hyperparameters and they usually relate to the structure of a neural network model. Both the modified
LSTM and stacked LSTM were subjected to parameter tuning, which is a process of changing various trainable
parameter in order to make the model perform optimally. After parameter tuning was done, the best model
was further evaluated by using cross validation.
Results have shown that the stacked LSTM model has the best performance among the three models.
It managed to reach F1 score of 0:7178 and able to identify 95% of the lane change data. However, the
stacked LSTM model has performance problems in terms of training time in identifying the transition phases
of lane change maneuver. Several factors…

▼ Thinking from a traveler’s perspective, it can be said that it is important to reduce travel time.
The Norwegian Public Roads Administration (NPRA) is working on a long term project to
extend the coastal highway route E39 as a continuous stretch of road between Kristiansand
and Trondheim. The road has a number of ferry crossings over fjords. Due to the depth in
the fjords, it is not possible to build conventional bridges. Thus, the objective is to reduce
the travel time by implementing a series of connections (e.g.submerged floating tunnels, subsea
road tunnels and floating bridges). One such fjord crossing is the Bjørnafjorden bridge which
spans for a length of over 5000 m.
The floating bridge will be exposed to a number of varied weather conditions of different
intensities. It is important to assess the vehicle handling and how the driver is experiencing
the moving road surface in these conditions. The bachelor thesis which was proposed on the
same topic, established a method to simulate the weather conditions in the CASTER driving
simulator at Chalmers. The Automotive Engineering project (AEP) aims at evaluating the
driving comfort and handling, when driving over the bridge in different weather conditions.
The main approach adopted is to simulate the driving conditions in CASTER driving simulator,
using the weather data provided by NPRA. Further, driving trials are conducted for a
combination of different weather conditions and vehicle speeds for car and bus models. The
results obtained from the trials are analyzed both subjectively using the driver feedback and
objectively using the data obtained from the driving simulator, to make suitable conclusions
and recommendations regarding the safe operating conditions of the bridge.
The project further concludes the correlation between the weather conditions and drivability
through both subjective and objective data analysis. The weather conditions were varied
from no wind condition to a 100-year storm condition. Also, the most frequently occurring
1-year storm condition was studied in detail with only wind on the vehicle, sea swell and wind
due to the wave conditions. A total of 157 driving trials were conducted with different vehicle
speeds (70 kmph, 90 kmph and 110kmph) and different maneuvers like lane change and
overtaking were performed to analyze the handling and stability of the car and bus. Straight
line driving is also simulated to determine the operating conditions of bridge, to check the safe
speed limit and ability of the driver to stay in lane.
Another deliverable of the project is to develop a driver model to perform a greater number
driving trials to test more conditions. Due to the lack of time and complexity of the weather
data, a basic driver model has been developed and a thorough literature survey has been done
to make suitable suggestions for the existing basic driver model as a future scope of the project.
To sum it up, the vertical and lateral dynamics of the vehicles driving over the bridge are
assessed in a…

▼ This study examines the benefits of Cooperative Intelligent Transport Systems (C-ITS) in weaving sections. The research proposes a lane-changing advisory application to alleviate the lane-changing concentration in weaving sections by coordinating weaving vehicles. While non-weaving vehicles travel as normal, weaving vehicles are monitored and advised through personalized messages based on their destination lane. The findings of this research, derived from a microscopic simulation in AIMSUN, reveal that the proposed strategy has the potential to improve delay significantly and that it can be applied to any existing one-sided weaving sections.

▼ In this paper, we propose a
lane changing model based on the collision cone approach. Specifically, we show how a vehicle decides whether to
change lanes using the collision
cone algorithm based on the velocity and the location of surrounding vehicles. The model not only checks the safety of a
lane change but also compares the current and target
lane
with a new measure of driving advantages. In addition, it determines if there are any existing driving advantages such as free space and speed by
lane changing. This is proved by showing how the
subject vehicle behaves in different situations. Moreover, a new methodology of
lane changing for collision avoidance, which is based on line of sight(LOS) with
a target leader in a target
lane, is suggested with a model predictive controller(MPC). Additionally, we show that the model makes reliable decision and generates acceptable
lane changing trajectories.

▼ The safety requirements for vehicles are today high and they will become more stringent in the future. The car companies test their products every day to ensure that safety requirements are met. These tests are often done by professional drivers. If the car is tested in an everyday traffic situation, a normal experienced driver is desired. A drawback is that a human will eventually learn the manoeuvre he/she is told to do. An artificial driver is therefore to prefer to make the test repeatable. This thesis’ purpose is to develop and implement an artificial driver as a controller in order to follow a predefined trajectory. The driver model’s performance driving a double lane change manoeuvre should be as close to a real driver’s as possible. Data was gathered by inviting people to drive in a simulator. The results from the simulator tests were used to implement three different drivers with different experiences. The gathered data was used to categorize the test drivers into different driver types for each specific velocity by using the vehicle position from thetest results. This thesis studies the driver from a controller’s perspective and it resulted in two implemented controllers for reference tracking. The first approach was a Model Predictive Controller with reference tracking and the other approach was to use a FIR-filter in order to describe the drivers’ characteristics. A vehicle model was implemented in order to do the double lane change manoeuvre in a simulation environment together with the implemented driver model. The results show that the two approaches can be used for reference tracking. The MPC showed good results with the recreation of the test runs that were made by the categorized drivers. The FIR-filter had problems to mimic the drivers’ test runs and their characteristics. The advantage with MPC is its robustness, while the advantages with the FIR-filter are its, in comparison, simplicity in the implementation and the algorithm’s low computational cost. In order to make the FIR-filter more robust, some improvements have to be made. One improvement is to use gain scheduling in order to adjust the filter coefficients depending on thevelocity.

I en vardaglig trafiksituation är det önskvärt att en normalt erfaren bilförare utför testen. En mänsklig förare kommer använda sin inlärningsförmåga vid repeterande manöver, vilket inte är önskvärt. En artificiell förare är därför att föredra. Den artificiella föraren ska köra så likt en verklig förare som möjligt vid en "double lane change"- (DLC) manöver. Detta examensarbete har som avsikt att implementera en förare som en regulator för att kunna följa en förutbestämd trajektoria på samma sätt som en verklig förare. I detta examensarbete har "DLC"-manövern…

▼ Balloon Cars (Soft Cars) used for active-system testing are presently statically following one specific path. Autonomous GPS driven balloon cars can be extremely useful if made to be accurate.Volvo group’s long term plan involves usage of such cars to improve active-safety systems. Thisreport presents comprehensive details about the development of the control system of the soft-car.Software development was preceded by purchase of parts. Detailed descriptions of the ballooncar hardware components are presented. Various hardware components were interconnected toform a CAN Bus network. This thesis work describes CAN networks in general and with referenceto the developed Linux based software system.The navigation system is presented in the thesis report using a ‘bottom up’ approach. First theLow-level functions and variables are described that directly control the hardware component.They are called by high level functions that are subsequently explained. The high level functionsinclude accurate turning and an automated lane change process.The high level functions may be sequentially called and to accurately follow a specific path. Various lines and points may be used in a user defined Cartesian coordinate system. Details about theperformance of various high level functions as well as of a demonstration of a pattern are presented along with the limitations of the overall system.

▼ Forest fires have been all over the news in Oregon the past two years, especially during the dry summer months which have hit record-high temperatures and record-long periods without rain. Due to nearly a century of fire exclusion, wildfires continue to get larger and wildfire season continues to get longer each year. This already devastating pattern is accelerated by climate change due to climate scientists predicting hotter and drier summers in the Pacific Northwest. Yet, existing literature shows climate change continues to be a low priority for the public. The media is one of the main avenues through which the public receives information about both forest fires and climate change. I hypothesized that most local media coverage of forest fires does not mention climate change. My thesis project analyzed local media coverage of forest fires and smoke here in Lane County using a content analysis: keyword searching for words such as ‘climate change’ and ‘global warming’ in relevant articles from May 2017 through November 2018. It was found that only 21.3% of Lane County media coverage of wildfires and smoke mentioned climate change. The purpose of demonstrating this lack of coverage is to start a discussion about the media’s role in communicating information about wildfires and climate change.

▼ Lane change manoeuvres are known to vary widely in lane change duration. This is thought to be an effect of the surrounding vehicles and personal preference of drivers. However, little is known about the effect on steering behaviour during a lane change manoeuvre. Moreover, the relation of the effect of traffic to inter- and intra-driver variability is unknown. This study focuses on quantifying inter- and intra-driver variability in lane change duration and steering behaviour during lane changes in two different traffic scenarios. In an exploratory study, 21 participants drove 30 lane change manoeuvres in a 6 DoF moving base driving simulator. Two scenarios were used: a closing gap in the target lane and a constant gap in the target lane, with 15 repetitions per scenario. The results show high inter-driver and intra-driver variability, for both lane change duration (M=6.34 s SD-inter=0.90 s SD-intra=1.26 s) and steering behaviour (e.g. maximum steering wheel angle M=4.14 deg SD-inter=1.62 deg SD-intra=1.34 deg). The effect of the scenario was not significant for lane change duration and maximum steering wheel angles. Additionally, it was shown that lane change duration only has a medium correlation with the maximum steering wheel angle (Pearson R(585)=-.48, pless0.001). Furthermore, the mean and variability of the lane change duration decreased when lane changes were initiated with a shorter distance to the slow lead vehicle. Concluding, the lane change duration does not fully determine steering behaviour during a lane change, making it an unsuitable metric for determining human-like lane change trajectories. It is therefore proposed to create trajectories based on steering behaviour. It seems that drivers exhibit high variability in lane change behaviour when spatio-temporal criticality with respect to traffic is low. Higher spatio-temporal criticality limits the mean and variability of the lane change duration. Future work should determine whether this variability is the result of driver preference or indifference. Additionally, future work should implement and test human-like lane change trajectories based on steering behaviour as opposed to lane change duration.

▼ Truck platooning is seen as a method to reduce truck emissions and labor hours in the transport industry. The effect that truck platooning will have on the other traffic receives less attention. In this thesis a methodology is proposed to model truck platoons, including a platoon level controller for lane changing. The model is used to estimate the on-ramp length that vehicles require in order to safely merge into the highway while interacting with platoons and the model is used to estimate the on-ramp length that truck platoons require in order to merge onto the highway if they would do so in platoon formation. Results show that onramps need to be at least 300 meters for other traffic to safely into the highway. For platoons to safely merge into the highway the required distance is heavily dependent on the crowdedness of the highway, ranging between 400-1000 meters of required on-ramp length.

▼ According the National Highway Traffic Safety Administration, more than 826,000 vehicles in North America are involved in
lane-
change accidents each year [1]. Although the fatality rate is low compared to other types of accidents, the extent of property damage and injury are high. This has therefore remained a cause of concern to the public. There are a few preventive devices that employ radar sensors have been advertised to use as blind spot detectors, but none of them looks promising or is commercially available to the automobile industry. Automakers have been longing to introduce their vehicles equipped with high-tech systems that can see beyond the driver's peripheral vision - the dangerous blind spots.
This project introduces a simple and inexpensive Optical Blind Spot Detection System (OBSDS) that is designed to assist drivers to consistently monitor the ???No Zones??? known as blind spots. The system uses a pair of infrared sensors to detect vehicles approaching the blind spots from the adjacent lanes and alert the driver with visual and audio signals before he or she proceeds on a
lane change.
The Optical Blind Spot Detection System was successfully designed and tested on a passenger vehicle. The maximum distance of detection is two meters. This range can be increased by adding more powerful infrared sensors to the circuit.
Another good application of the OBSDS is for parallel parking. In this case, the system is used as an aid for detecting the distance between the bumpers of a vehicle and any objects behind it. The distances can be understood from the combination of the visual and audio alerts.
With the addition of a motion detector circuit, the OBSDS can also be used to detect the present of pedestrians at intersection traffics. This is a very useful application to help reducing the pedestrian deaths which occur in 17 percent of all traffic fatalities [2].

▼ Road transport is a major societal and economic activity. Despite its importance, road transport raises a number of challenges that have to be dealt with. Road safety is the most important of them. Fatal road accidents lead to the death of 1.35 million people annually, while they are the 8th cause of death worldwide and the 1st cause of death for the people who belong to the age group 5-29 year-old.Road safety and traffic flow theory constitute an important research and study field. In the framework of this thesis risk conditions in freeways are studied microscopically. Two traffic incidents are considered as risk conditions: shockwave and forced lane change. These two incidents are non-catastrophic incidents, which are used as crash surrogates. The research studies about these incidents have focused on the characteristics of the phenomena, their interpretation, their mechanisms and laws as well as their impact on traffic flow. There is though a lack of research on the causes generating these incidents and on their description. To better understand the risk conditions a large dataset of vehicle trajectories has been developed. The extracted trajectories correspond to vehicles involved in two traffic incidents, shockwave and forced lane change respectively. These incidents are spotted after watching several hours of traffic video recordings. Moreover, trajectories of vehicles not involved in incidents are developed. The trajectories dataset, which was developed manually, is different from the widely used dataset of NGSIM, as it focuses on incidents instead of continuous traffic and it offers the possibility to watch the video recordings of the traffic which correspond to the trajectories. After the calibration of the trajectories, the traffic variables which describe the traffic flow microscopically are selected. For the incidents the value of the variables are calculated for the start time of the incidents. For forced lane changes, start time is considered the moment when the vehicles starts maneuvering to change lane. For shockwaves, start time is considered the moment when the driver starts braking. For incident-free flow, the variables are calculated at random moments. For the most efficient study of the data, 4 populations are generated: population A, which includes all incidents -both shockwaves and forced lane changes- and incident-free flow, population B which includes shockwaves and incident-free flow, population C which includes forced lane changes and incident-free flow, and population D which includes only incidents, shockwaves and forced lane changes. The values of the variables, which have been developed based on the dataset, are clustered by employing two clustering algorithms based on cost function minimization: K-means algorithm and Fuzzy c-means algorithm. To implement the algorithms: a) the number of the clusters is determined; in all four populations it is well-known that there are two clusters, b) the couple of variables used is defined, c) the algorithms are implemented, and d) the algorithm…

▼ The development of intelligent vehicle and autonomous driving asked a higher requirement of ADAS on its functionality. Currently, ADAS systems are able to detect and segment urban and highway driving scenes. They cannot, in general, extract ’meaning’ from this segmentation yet. Learning the intention of other road users will help ADAS understand surroundings and make a response. In a highway scenario, understanding what the preceding vehicle is about to do, is the minimum level of understanding the environment in order to take a decision about your own actions. Among the driving behaviors the preceding vehicle could do, lane change is a complex and dangerous one. Thus, we aimed to develop a real-time lane change intention recognition model. This report presents three models inspired by the Hidden Markov Models (HMMs) and Relevance Vector Machines (RVMs). Besides these two methods, we proposed a new model which combines them and overcome both of their main shortcomings. According to the testing result, the proposed model can correctly recognize more than 95% of the driving behaviors within 1 second the behavior starts, while the F1 score is also as high as 0.98. Besides the high accuracy, the model also has a good performance on the flexibility, testing complexity and the generalization ability.

▼ Cognitive psychological
experimental work on response preparation is generally conducted
under highly controlled laboratory conditions. Adequate temporal as
well as eventspecific preparation typically support the
individual’s response preparation, for example in terms of reduced
reaction times (RT) on imperative stimuli. By contrast,
psychological research on driving tends to be conducted under
realistic conditions, for example in the field or in sophisticated
driving simulators. This research has largely overlooked the extent
to which mechanisms of action preparation support the driver's
reactions. Despite these two different approaches, the concept of
action preparation should be highly applicable to vehicle steering,
since driving requires the driver continuously to anticipate
immediate and future traffic situations. Starting from this
assumption, this dissertation’s first aim is to transfer basic
experimental paradigms on action preparation – that is, temporal
and event-specific preparation – into a driving task. Second, the
predictions derived from cognitive psychological groundwork will be
tested in this applied setting in order to replicate and enhance
the corresponding findings. A priori it was not clear whether
temporal and eventspecific preparation would lead to comparable
results in a driving task, since a continuous driving task with
complex bimanual steering movements is quite different from
discrete single finger reactions in a typical laboratory task.
Third, one of the basic paradigms on action preparation will be
modified and transferred to an applied question in order to
exemplify its usefulness for concrete problems in driving research.
For these purposes, a
lane change task was developed in a virtual
reality environment. With the help of this experimental driving
task, processes of temporal preparation as well as of
event-specific preparation were examined in a first series of five
experiments. Temporal preparation was implemented according to a
variable foreperiod paradigm, while eventspecific preparation was
realized according to the movement precuing and the response
priming paradigm. Aside from measuring the reaction time (RT) on
the imperative
lane change signals, kinematic properties of the
lane change steering wheel movement were evaluated. To this end,
the entire
lane change movement was divided into three
submovements, the first two of which were eventually analyzed in
terms of their velocity profiles. It was generally predicted that
temporal and event-specific response preparation would reduce RTs
and lead to result patterns comparable with evidence in the
respective cognitive psychological literature. In keeping with the
"movement integration"-hypothesis (Adam et al., 2000) and in
accordance with the findings of van Donkelaar and Franks (1991a),
kinematic effects were expected around the first peak steering
wheel angle of the
lane change steering wheel movement. Eventually,
the sixth and seventh experiment served to examine the applied
question whether a 3-dimensional conformal…

▼ In recent years, autonomous driving has become an increasingly practical technology. With state-of-the-art computer and sensor engineering, autonomous vehicles may be produced and widely used for travel and logistics in the near future. They have great potential to reduce traffic accidents, improve transportation efficiency, and release people from driving tasks while commuting. Researchers have built autonomous vehicles that can drive on public roads and handle normal surrounding traffic and obstacles. However, in situations like lane changing and merging, the autonomous vehicle faces the challenge of performing smooth interaction with human-driven vehicles. To do this, autonomous vehicle intelligence still needs to be improved so that it can better understand and react to other human drivers on the road. In this thesis, we argue for the importance of implementing ”socially cooperative driving”, which is an integral part of everyday human driving, in autonomous vehicles. An intention-integrated Prediction- and Cost function-Based algorithm (iPCB) framework is proposed to enable an autonomous vehicles to perform cooperative social behaviors. We also propose a behavioral planning framework to enable the socially cooperative behaviors with the iPCB algorithm. The new architecture is implemented in an autonomous vehicle and can coordinate the existing Adaptive Cruise Control (ACC) and Lane Centering interface to perform socially cooperative behaviors. The algorithm has been tested in over 500 entrance ramp and lane change scenarios on public roads in multiple cities in the US and over 10; 000 in simulated case and statistical testing. Results show that the proposed algorithm and framework for autonomous vehicle improves the performance of autonomous lane change and entrance ramp handling. Compared with rule-based algorithms that were previously developed on an autonomous vehicle for these scenarios, over 95% of potentially unsafe situations are avoided.

▼ In this Thesis, we focus on the analysis of driver lane-changing behavior based on the fact that lane changing is a ubiquitous driving maneuver in common driving environments and regarded as the most critical driving intention. Therefore, lane changing as a case study for driving intention recognition is introduced in this study. Our methodology is to employ machine learning method i.e., support vector machine, to the classification of driving intentions using vehicle performance data and driver eye gaze data from the measurement of the driving tasks (i.e., lane following and lane changing) in the well-designed simulation environment. To improve recognition performance, this thesis illustrates the use of entropy based fusion method to discard those largely negative dependent data to decrease the redundancy level of input data. Based on entropy correlation coefficient analysis, heading angle, as one kind of performance data, is harmful for recognition result. Incorporation of eye gaze data enhances the recognition performance. Introduced by three-stage nested design, experiments are executed to screen out the best "supplies" for pattern learning. Final results show that feature set fused by steering angle, gas pressure, velocity and acceleration performance data as well as eye gaze data achieves 88.78% accuracy with a time length of 0.6 seconds at 5% false alarm level.

▼ As a component of Dutch Automatic Vehicle Initiative (DAVI) project, this study aims at improving highway driving safety of autonomous vehicle. It is observed that some misbehaved drivers do not use turn indicators forehead a lane change on highway. For a self-driving car in such situations, a lane change is potentially dangerous without an accurate estimation of other vehicles’ movements .If lane changes can be detected or predicted at its initial phase, DAVI vehicle can be advised in time to perform corresponding maneuvers to avoid collision. In this study, a Support Vector Machine (SVM) based method was proposed to fulfil this task. Predictions are generated through analysing vehicles’ motion parameters. At the first place, a number of driving simulator tests were carried out to set up database of typical vehicle maneuvers features, including heading angle, yaw rate, lateral velocity and lateral acceleration. 14 driver databases were used in SVM training after removal of unrealistic info. An off-line trained SVM was obtained to perform lane change predictions. In addition to offline training, an incremental training SVM was introduced. Compared with off-line learning, its incremental feature enables the classifier to update itself with freshly recorded lane change data in a relatively short time. This enables the vehicle to be "learning while predicting" . Based on the databases, SVM based approaches were verified to be feasible of predicting lane changes. With the most optimal parameter combination, this method is able to perform predictions with 100% sensitivity ( predicted all lane changes successfully). Average advance time and average computational time are acceptable for automatic driving. Besides, the performance of sliding window method was evaluated for variation of its size, and a general applicability of overall prediction method was also examined on data from different drivers.

▼ Nowadays, a driver interacts with multiple systems while driving. Multimodal in-vehicle technologies (e.g., Personal Navigation Devices) intend to facilitate multitasking while driving. Multimodality enables to reduce cognitive effort in information processing, but not always. The present study aims to investigate how/when auditory cues could improve driver responses to a visual target. We manipulated three dimensions (spatial, semantic, and temporal) of verbal and nonverbal cues to interact with visual spatial instructions. Multimodal displays were compared with unimodal (visual-only) displays to see whether they would facilitate or degrade a vehicle control task. Twenty-six drivers participated in the Auditory-Spatial Stroop experiment using a
lane change test (LCT). The preceding auditory cues improved response time over the visual-only condition. When conflicting, spatial congruency has a stronger impact than semantic congruency. The effects on accuracy was minimal, but there was a trend of speed-accuracy trade-offs. Results are discussed with theoretical issues and future works.

▼ Distraction from the use of mobile phones has been identified as one of the causes of road traffic crashes. Voice control technology has been suggested as a potential solution to driver distraction by the manual use of mobile phones. However, new evidence has shown that using voice control interfaces while driving could require more from drivers in terms of cognitive load and visual attention compared to using a mobile phone manually. Further, several factors that moderate the use of voice control interfaces, for example, usability and acceptance are poorly understood. Thus, the current study aims to investigate the safety impact of using voice control interfaces on driving performance. A preliminary study, an online survey and a driving experiment were conducted to investigate how drivers interact with smartphone voice control interfaces and their effects on driving performance. First, the usage pattern of voice control interfaces while driving was explored using focus groups and interviews (preliminary study) and an online survey. Next, 55 participants completed a simulated driving task that utilises a valid and standardised method called the
Lane Change Test (LCT). The purpose was to measure degradation of driving performance due to the concurrent performance of secondary tasks; either contact calling, playing music or text messaging task. These secondary tasks were identified as common tasks in the survey of the pattern of use of voice control interfaces while driving. Secondary tasks were performed in both visual-manual and voice control modes with either an Apple or a Samsung smartphone. Data on eye glance behaviour, workload and, usability and acceptance of the voice control interfaces were also collected. Findings support the view that interacting with voice control interfaces while driving reduces distraction from visual-manual interfaces but is still distracting compared to driving without using any devices. Texting was found to degrade task and driving performance regardless of control modes and phone type. Moreover, poor system performance leads to low acceptance of voice control technology. Smartphone voice control interfaces have an apparent advantage over visual-manual interfaces. However, they still can impose some elements of distraction that may have negative implications for road safety.

▼ Over the years microscopic traffic simulation has evolved as the premier tool to analyze complex and congested transportation networks. However, despite the robustness and wide spread use of traffic microsimulation, some gaps and limitations still exist that can affect the accuracy of these models' results. Moreover the
change of traffic characteristics and driver behavior during the transition from undersaturated to saturated condition is not completely understood. This dissertation addresses these two issues. The road network chosen for the microscopic simulation and field data collection is a six
lane main traffic artery located in Tuscaloosa, Alabama, USA. The entire research work contains three related research efforts, each conducted along the topic of this dissertation. The first research thrust focused on the sensitivity and accuracy of the microscopic traffic simulation. Specifically it investigated the sensitivity of MOEs to simulation initialization time, required number of repetitions, and major contributors of variation in MOEs. The second research thrust dealt with field investigation of operational parameters including gap acceptance and
lane changing during different levels of traffic flow. The final research effort explored the variations in simulation results using existing embedded/default values of
lane change parameters (
lane change duration and look ahead distance), versus using values obtained from field observation for both free flow and saturated traffic conditions. From all the research efforts, the following broad conclusions were drawn, * Traffic flows at signals that are approaching saturation are still complex to analyze, and the interactions between traffic parameter are not well understood. * When traffic flow on a typical arterial approaches saturation, drivers take higher risks (eg: drivers accept smaller gaps). * A statistical analysis of gap acceptance and
lane changing confirmed what is suspected intuitively. * Existing traffic microsimulation tools simplify some of the traffic parameters in simulation models. These parameters may be recoded or recalibrated for better accuracy of simulation results. * In traffic microsimulation an increased number of simulation runs certainly helps in stabilizing the variability of the MOE and it is advisable to use a longer simulation time (eg. 60 minutes) to reduce the variation of MOEs.

▼ This study develops an advanced speed control strategy called “differential variable speed limit (DVSL)”. DVSL assigns different speed limits for car and truck, and it also varies speed limits based on traffic conditions. The study tested the impacts of DVSL on delay and safety for a section of the Gardiner Expressway in Toronto, Canada. In this study area, recurrent congestion occurs due to a sudden increase in entry traffic volume from an on-ramp after it is open. Traffic in uncongested and congested periods was simulated using the VISSIM traffic simulation model. The impacts of the following four different speed limit strategies on traffic were evaluated: 1) uniform speed limit (USL), 2) differential speed limit for car and truck (DSL), 3) USL & DSL (U&D) – i.e., USL at low truck percentage and DSL at high truck percentage, and 4) DVSL. It was found that DVSL showed the lowest delays for both car and truck among the four speed limit strategies. DVSL also had the lowest number of truck
lane changes but it had higher number of car
lane changes than USL and U&D. This increase in the number of car
lane changes rather created more spacing between vehicles in the right
lane upstream of the on-ramp. More spacing allowed the vehicles from the on-ramp to merge with the mainline traffic more smoothly. Safety impacts of DVSL were also assessed based on the “Crash Potential Index (CPI)” which represents the likelihood of rear-end crash between the lead and following vehicles. The result shows that among the four speed limit strategies, DVSL had the lowest CPI for car-following-car, car-following-truck and truck-following-car conflicts. This study demonstrates that DVSL can better control car and truck speeds to reduce delay and improve safety of car-truck mixed traffic flow on freeways.

▼ La congestion routière est le résultat d’un excès de la demande sur l’offre. Sur le réseau autoroutier en particulier, la congestion apparaît soit en section courante, soit au niveau des bretelles d’accès, des bretelles de sortie ou des zones d’entrecroisement qui sont généralement appelées les discontinuités ou nœuds du réseau routier. Les objectif de la thèse sont (i) d'apporter des éclairages sur la phénoménologie du trafic au droit des discontinuités du réseau autoroutier et (ii) de proposer des modèles macroscopiques pour en prédire le fonctionnement et évaluer des stratégies d'optimisation de l'écoulement du flux. Contrairement aux modèles existants, les modèles proposés dans cette thèse prennent en compte les phénomènes physiques du trafic en intégrant explicitement les comportements individuels des usagers. Après avoir présenté les outils méthodologiques et expérimentaux mobilisés, la thèse propose une analyse empirique des changements de voie à partir de données individuelles de trajectoires. Sur la base des résultats empiriques, la thèse présente ensuite les modèles analytiques développés qui sont utilisés dans une dernière partie pour proposer des stratégies d'optimisation de l'écoulement du flux du trafic.
The congestion occurs when the demand is higher than the supply. On the highway network, the congestion forms on the diverges, the merges and the weaving section which are generally named the discontinuities of the network. The thesis aims at (i) investigating the traffic phenomenology at the discontinuities of the highway network and (ii) developing macroscopic traffic flow model to forecast their operation and evaluate traffic regulations. Those models will explicitly integrate the drivers' microscopic behaviors. The thesis presents first the methodological and experimental tools. Then, it proposes an empirical analysis of the lane-changes at two merges and one weaving sections. The thesis describes the analytical models while it ends with operational applications of those models.

▼ In the past years a number of SAE level 2 driving automation systems have come available in commercial vehicles. An example is Volvo's Pilot Assist, which provides a more comfortable journey for the driver as certain parts of the dynamic driving task are taken away, but it still requires the driver to be attentive in order to supervise the system and resume vehicle operation if necessary. Car manufacturers and high-tech companies all around the world are working on the development of an Automated Driving System (ADS) of level 3 or higher where the driver does not need to supervise, but have so far not been able to introduce any to the public. Operating a vehicle on an empty highway is relatively easy, but roads are getting more and more congested so dense traffic driving needs to be accounted for as well. Unsupervised driving does not only require that a system itself operates the vehicle correctly, but requires that it is able to cope with mistakes of other drivers. In order to take these into account as well as other unpredictable events, current driving automation systems tend to adopt large longitudinal margins with respect to surrounding traffic to use their ability to brake to avoid a collision. In dense traffic situations this conservative behaviour prohibits the ADS from making
lane changes. This thesis was setup in cooperation with Volvo Cars / Zenuity to develop a
lane change path planning algorithm that can plan active
lane changes in dense traffic, by pushing into a gap without compromising the ability to avoid a possible collision. Earlier work at Volvo suggested considering the ability of a vehicle to not only brake, but also to make an evasive maneuver. If an evasion maneuver is available the necessary safety margins are reduced considerably compared to a `braking-only' scenario. In this work, the evasive maneuver was modeled and a constraint formulation was developed that if met, guarantees the availability of the designed evasion maneuver. This constraint translates to a state-dependent safety zone which the ADS should keep the vehicle clear off at all times. Model Predictive Control allows the implementation of such a safety zone by considering it as a constraint on the optimisation, guaranteeing that an evasion maneuver is available along any point on the prediction horizon. This negates the necessity to plan all possible evasion maneuvers separately, and it was therefore chosen as the path planning method. Implementation of the safety zone constraint on multiple surrounding vehicles, spread over multiple lanes in a Model Predictive Control framework, together with the requirements of being able to overtake other vehicles within the prediction horizon, necessitated the development of a novel 3-step algorithm. In this algorithm three Optimal Control Problems are solved consecutively to plan a path which positions the ego-vehicle optimally in the targeted gap without breaching the safety zones. To be able to implement the algorithm in…

▼ This study analyzes car-following and
lane-
change conflicts in car-heavy vehicle mixed traffic flow on freeways using three surrogate safety measures - time-to-collision (TTC), post-encroachment-time (PET) and crash potential index (CPI). The surrogate safety measures were estimated for different types of lead and following vehicles (car or heavy vehicle) using the individual vehicle trajectory data. The data were collected from a segment of the US-101 freeway in Los Angeles, California, U.S.A. For car-following conflicts, the distributions of TTC and PET were significantly different among different types of lead and following vehicles. For
lane-
change conflicts between the
lane-
change vehicle and the trailing vehicle in the target
lane, CPIs were higher for angle conflicts than rear-end conflicts. It was also found that the CPI was generally higher for a given spacing interval when the following vehicle is a heavy vehicle in both car-following and
lane-
change conflicts. This indicates that heavy vehicle’s lower braking capability significantly increases collision risk. This study also validates the CPI using historical crash data and the loop detector data extracted a few minutes before crash time upstream and downstream of crash locations. The data were obtained from a section of the Gardiner Expressway, Ontario, Canada. The result shows that the values of CPI were consistently higher for the crash case than the non-crash case. This shows that CPI can be used to capture the collision risk during car-following and
lane-
change maneuver on freeways. The findings suggest that the differences in collision risk among different vehicle pair types should be considered in the assessment of safety of car-heavy vehicle mixed traffic flow.

▼ Lane changing is one of the most complex tasks during driving. Advances in vehicle technology seek to help drivers during the
lane change maneuver. Researchers have conducted many attempts to address this issue. However, most of these attempts have not focused on actual driver behavior using advanced vehicle technologies. Among those advances is the vehicle-to-vehicle (V2V) communication which promises safer and more efficient driving operations. This research seeks to fill in this gap by conducting an experiment in a driving simulator environment simulating V2V communication during a
lane change maneuver. The experiments allow a better understanding of driver behavior during
lane changing maneuvers. First, a literature review was completed to assess studies that focused on understanding and modeling discretionary
lane changes. Then a pilot study was conducted with a small sample on a driving simulator to obtain a fuzzy logic membership function. Then a large sample was tested for the study. Adjustments were made to the model and performance measures were analyzed. A t-test was conducted to evaluate any significant differences between the two conditions with and without V2V communication. The results showed that drivers were more willing to accept smaller gaps under connected environment conditions than without V2Vcommunication. Also, the implementation of V2V communication was found to help drivers make the
lane changing decision faster. The overall initial speed was reduced under the connected environment.
