Abstract:
Despite the success of various engineering, education, and enforcement measures, fatalities and injuries from traffic collisions remain one of the major global problems. It has been advocated that addressing this massive problem requires a fundamental transformation in the traffic safety culture of road users. Measuring and understanding traffic safety culture has gained growing attention in the field of traffic safety. This study, believed to be the first of its kind in Canada, aimed to ( a) measure traffic safety culture related to distracted driving, impaired driving, and speeding; ( b) investigate how perceptions of these major issues are associated with self-reported behavior and support for related enforcement and policy; and ( c) explore the effect of respondents’ sociodemographic characteristics on traffic safety culture. A telephone survey based on a stratified random sample of approximately 1,000 residents in the Edmonton region of Alberta, Canada, was conducted in 2014. Descriptive analysis, multivariate confirmatory factor analysis, and structural equation modeling were performed. The results demonstrate statistically significant correlations among perceived threat to personal safety, acceptability of behaviors, self-reported behaviors, support for enforcement, and support for law and policy. Perceived threat to personal safety has a statistically significant influence on self-reported behavior, support for enforcement, and support for law and policy. Various sociodemographic characteristics have a significant effect on the perceived threat of traffic behaviors to personal safety. The results can be used to guide educational campaigns to transform traffic safety culture from one that is risk receptive to one that is protective.

Abstract:
Fast development of the number of vehicles is closely related not only to large benefit for the public but also to certain undesirable social and economic consequences. Firstly — large numbers of injured and killed people are involved into the accidents. The target to improve traffic safety situation in Lithuania can be reached only after the detailed evaluation of transport system, environment, traffic participants, road and vehicle. Taking into consideration the accident situation in Lithuania and its causes the followings priority trends are suggested: The improvement of the coordination of road traffic safety system, the training and education of road users, the explanation of the importance of traffic safety and its propagation, the improvement of traffic conditions. Recommendations and proposals for differentiated criterion of maximum speed limit selection taking into account different factors are provided in the work.

Abstract:
Motor vehicle crashes (MVCs) have a huge cost to society in terms of death, injury and property damage. The cost of fatal MVCs alone is estimated at US $44 billion per year. Among many confounding factors, traffic citations as an element that may reduce MVC frequency are not well understood, and most research carried out to date has evaluated the effects of the total number of citations on the number of MVCs. However, certain types of citations may be more likely to reduce the number of MVCs, whereas other types are not very effective. This research was set out to examine the impact of different types of traffic citations on MVCs on two hazardous main US highways in Wyoming US-30 and US-26. A negative binomial modeling technique was implemented by exploiting 4 years of crash and citations data to identify the causal impacts of traffic citations on crash frequency by incorporating traffic and geometric features. The modeling results showed that higher numbers of speeding and seat belt citations reduce the number of crashes significantly. These findings are the results of law enforcement efforts along the highways. Traffic count and the number of horizontal curves were found to significantly increase the number of MVCs.

Abstract:

As one of the highest fatalities causes, traffic accidents and collisions always requires a large amounteffort to be reduced or prevented from occur. Traffic safety management routines therefore always needefficient and effective implementation due to the variations of traffic, especially from trafficengineering point of view apart from driver education.Traffic Accident Prediction Model, considered as one of the handy tool of traffic safety management,has become of well followed with interested. Although it is believed that traffic accidents are mostlycaused by human factors, these accident prediction models would help from traffic engineering point ofview to enlarge the traffic safety level of road segments. This thesis is aiming for providing a guidelineof the accident prediction model implementation in traffic safety management, regarding to trafficengineering field. Discussion about how this prediction models should merge into the existing routinesand how well these models would perform would be given. As well, cost benefit analysis of theimplementation would be at the end of this thesis. Meanwhile, a practical field study would bepresented in order to show the procedures of the implementation of traffic accident prediction model.The field study is about this commercial model set SafeNET, from TRL Limited UK, implemented inRoad Safety Audit procedures combined with microscopic simulation tool. Detailed processing andinput and output data will be given accompany with the countermeasures for accident frequencyreduction finalization.

Abstract:

Transportation has expanded the scope of human mobility, increasing the distances we cover on a

regular basis. The large benefits of transportation have resulted in a huge recent increase in the

number of vehicles. This, however, implies an increased number of traffic accidents that cause

many fatalities and injuries every year. It also leads to problems like increased delay for

commuters, and negative effects on the environment. Not to mention, the money spent in the

wasted fuel, as well as the costs of fixing damaged equipment and property.

To help in mitigating these problems the vehicles and the road infrastructure should be equipped

with intelligent devices that allow them to communicate and collaborate with each other and

exchange safety information concerning accidents, road traffic conditions, and weather conditions

as well as non-safety information. Recently, this topic termed telematics has gathered

considerable interest constituting a lot of work and research all included under the title of

Intelligent Transportation System (ITS).

The thesis work defines general communication requirements of future telematics applications

and investigates various wireless carriers that are important to achieve communication inbetween

vehicles and between vehicles and nearby infrastructure. We analyse several future

applications related to the ITS field and describe their communication requirements. Based on the

communication requirements the applications are grouped into different profiles in order to

determine the most suitable carrier for each profile.

Abstract:
National and statewide (California) collision numbers are currently on the decline; however, the U.S. is declining at a much slower rate than most other developed countries, and in some aspects is actually regressing in terms of traffic safety. Although state highway safety is improving, local roadway safety may actually be regressing. Approximately three-quarters of all U.S. public roadways, and approximately 80% of all injury accidents fall under the jurisdiction of cities. However, cities may not be allocating the proper level of resources, or operating under the proper administrative methodologies to adequately address these safety issues. This research finds that on average, California cities are experiencing increasing annual collision rates. In particular, small cities with populations of less than 25,000 are experiencing the largest increases, whereas larger cities are experiencing static or slightly decreasing collision rates. California’s statewide collision statistics and the administration surveys conducted as part of this study indicate that there is a correlation between a city’s administrative analysis/mitigation methodologies and their annual collision rate trends. Specifically, cities with lower traffic engineering staff to population ratios tend to have increasing collision rates, as opposed to cities with high staff to population ratios, which have decreasing collision rates. Also, this research shows that cities that allocate more traffic safety resources to enforcement over engineering tend to have increasing collision rates, as opposed to cities allocating more resources to engineering that have decreasing collision rates. This research also finds that there are predominant and correctable factors that lead to the various collision types. Cities that employ routine system wide traffic safety audits addressing location-specific collision trends based on these predominant factors tend to have decreasing collision rates, as opposed to those that do not. In general, collision rates among U.S. cities are increasing largely due to increasing rates on roadways within the jurisdiction of smaller cities, most commonly with populations under 25,000. Over one-third of cities are not staffed at the proper levels, not allocating the necessary resources to traffic engineering activities, and are not employing an adequate evaluation/mitigation strategy. The findings of this study provide guidance and framework to cities for developing effective traffic safety strategies by identifying the characteristics of those cities that have been successful in reducing collision rates as examples. In particular the value of this research is important for non-engineering administrative staff and political bodies in terms of establishing appropriate staffing levels and resource allocations necessary for an effective traffic safety program. The findings of this study provide guidance and framework to cities for developing effective traffic safety policy preference by identifying the characteristics of those cities that have been successful in reducing collision rates as examples. In particular this research is important for non-engineering administrative staff and political bodies in terms of establishing appropriate staffing levels and resource allocations necessary for a transportation department to be effective in reducing traffic collisions and resulting damages.

Abstract:
The main aim of the study was to determine values and attitudes of primary school learners towards traffic safety and traffic safety education. The role played by parents and teachers in developing positive values and attitudes towards traffic safety and traffic safety education was determined. It was important to find out what can be done by parents and school to teach traffic safety education to learners. Key concepts like values, attitudes, traffic, safety and. education are discussed in details in this study. A group of learners was selected from fifteen primary schools in Potchefstroom to conduct this study. The main aim was to determine their values and attitudes towards traffic safety and traffic safety education. A questionnaire was developed whereby learners, their parents and their teachers had to fill it out in order to reach the objectives of this study. From. the response of learners, it was evident that learners really value their safety and that it is important for them to be safe road users. They even showed interest in including road safety education in their school curriculum. The school and parents also showed interest in traffic safety education being included in their children's school curriculum. They even opted to help teaching their children. The response of the learners, teachers and parents was positive and this indicated how possible it can be to implement/teach traffic safety education in schools. The. study was successful and it is hoped that the teachers can use it to their own benefit and to the benefit of their learners.

Abstract:
Numerous extant studies are dedicated to enhancing the safety of active transportation modes, but very few studies are devoted to safety analysis surrounding transit stations, which serve as an important modal interface for pedestrians and bicyclists. This study bridges the gap by developing joint models based on the multivariate conditionally autoregressive (MCAR) priors with a distance-oriented neighboring weight matrix. For this purpose, transit-station-centered data in Los Angeles County were used for model development. Feature selection relying on both random forest and correlation analyses was employed, which leads to different covariate inputs to each of the two jointed models, resulting in increased model flexibility. Utilizing an Integrated Nested Laplace Approximation (INLA) algorithm and various evaluation criteria, the results demonstrate that models with a correlation effect between pedestrians and bicyclists perform much better than the models without such an effect. The joint models also aid in identifying significant covariates contributing to the safety of each of the two active transportation modes. The research results can furnish transportation professionals with additional insights to create safer access to transit and thus promote active transportation.

Abstract:
The current safety management program in Indiana uses a method based on aggregate crash data for conditions averaged over several-year periods with consideration of only major roadway features. This approach does not analyze the risk of crashes potentially affected by time-dependent conditions such as traffic control, operations, weather and their interaction with road geometry. With the rapid development of data collection techniques, time-dependent data have emerged, some of which have become available for safety management. This project investigated the feasibility of using emerging and existing data sources to supplement the current safety management practices in Indiana and performed a comprehensive evaluation of the quality of the new data sources and their relevance to traffic safety analysis. In two case studies, time-dependent data were acquired and integrated to estimate their effects on the hourly probability of crash and its severity on two selected types of roads: (1) rural freeways and (2) signalized intersections. The results indicate a considerable connection between hourly traffic volume, average speeds, and weather conditions on the hourly probability of crash and its severity. Although some roadway geometric features were found to affect safety, the lack of turning volume data at intersections led to some counterintuitive results. Improvements have been identified to be implemented in the next phase of the project to eliminate these undesirable results.

Abstract:
To improve traffic performance and safety, the ability to measure traffic accurately and effectively, including motorists and other vulnerable road users, at road intersections is needed. A past study conducted by the Center for Road Safety has demonstrated that it is feasible to detect and track various types of road users using a LiDAR-based system called TScan. This project aimed to progress towards a real-world implementation of TScan by building two trailer-based prototypes with full end-user documentation. The previously developed detection and tracking algorithms have been modified and converted from the research code to its implementational version written in the C++ programming language. Two trailer-based TScan units have been built. The design of the prototype was iterated multiple times to account for component placement, ease of maintenance, etc. The expansion of the TScan system from a one single-sensor unit to multiple units with multiple LiDAR sensors necessitated transforming all the measurements into a common spatial and temporal reference frame. Engineering applications for performing traffic counts, analyzing speeds at intersections, and visualizing pedestrian presence data were developed. The limitations of the existing SSAM for traffic conflicts analysis with computer simulation prompted the research team to develop and implement their own traffic conflicts detection and analysis technique that is applicable to real-world data. Efficient use of the development system requires proper training of its end users. An INDOT-CRS collaborative process was developed and its execution planned to gradually transfer the two TScan prototypes to INDOT’s full control. This period will be also an opportunity for collecting feedback from the end user and making limited modifications to the system and documentation as needed.
