Available in PDF, EPUB and Kindle. Book excerpt: Previous FHWA research on pedestrian exposure identified four problem areas as promising candidates for accident reduction: intersections without marked pedestrian crosswalks, major arterial streets, local streets, and locations lacking sidewalks or pedestrian pathways. This report describes the results of a project undertaken to examine those four problem areas. The objectives of the project were to: evaluate past research on pedestrian crosswalk markings and develop guidance for when and what type of crosswalk markings should be provided; investigate traffic engineering improvements for major arterial streets to increase pedestrian safety; investigate traffic engineering improvements for local streets to increase pedestrian safety; and examine existing guidance/warrants for the provision of pedestrian pathways and sidewalks and prepare revised guidance/warrants.

This book was released on 2012 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, there is no commonly accepted or adopted measure of pedestrian and bicyclist exposure. This report presents a methodology for measuring a region's pedestrian and bicyclist exposure, which is defined as 100 million pedestrian/bicyclist mi (161 million pedestrian/bicyclist km) of roadway (or other motor vehicle shared facility) traveled. A method for implementing the exposure measure is described for various shared facility types that are characteristic to the urban environment of Washington, DC. These facilities include three types of intersections (signalized, stop-controlled (all-way), and partially stop-controlled) as well as midblock road segments, driveways, alleys, parking lots, parking garages, school areas, and areas with playing/dashing/working in the roadway. A pilot study demonstrated the feasibility of the method at seven sites in Washington, DC, in 2006. In 2007, the methodology was implemented on a larger scale to estimate the annual pedestrian and bicyclist exposure in Washington, DC, which was 0.80 hundred million mi (1.29 hundred million km) for pedestrian exposure and 0.37 hundred million mi (0.59 hundred million km) for bicyclist exposure. As a result of simplifications in the present data aggregation technique, these particular exposure values are overestimated. However, procedural changes are suggested to correct this issue. Within the constraints of this study, both the feasibility and scalability of the methodology were successfully demonstrated for a relatively large urban environment. The results indicate that the methodology has the potential to be used to collect exposure data that are not currently readily available to the pedestrian and bicycle safety community. Although further refinement and validation are still needed, the methodology provides a possible initial foundation to develop a national unit of exposure for pedestrians and bicyclists.

This book was released on 2013 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walking is an indispensable travel mode in the transport system; almost all road users are pedestrians for all or part of their trip. It is also among the most environmentally sustainable transport modes and its promotion has been rigorously advocated since the rise of concern about global warming and environmental degeneration. Moreover, as a form of physical activity, walking has considerable benefit for public and individual health. Notwithstanding the positive aspects of walking, there are a number of barriers preventing people from walking as a mode of travel, with the lack of safety chief amongst these. The focus of this thesis, therefore, was to address the pedestrian safety problem by identifying factors associated with pedestrian crash occurrence and with the severity of injuries sustained.The Central Business District (CBD) of Melbourne was selected as the case study for this research. This site has a high level of pedestrian activities and high pedestrian crash rate. The PhD research aims to address the following questions:1.What is an appropriate design for a pedestrian road safety data system to collect the data necessary for pedestrian safety analysis in the Melbourne CBD?2.Using the tools developed in 1, what are the risk factors for pedestrian crashes in the Melbourne CBD:a)What are the characteristics of the physical and socioeconomic environment and the transport system that influence the occurrence of pedestrian crashes?b)What are the characteristics of the physical and socioeconomic environment, the transport system, road users (drivers/pedestrians) and traffic that influence the severity of injury sustained by pedestrians in traffic crashes?A principal contribution of this research was the development of a conceptual framework for studying pedestrian safety. A review of the available pedestrian data systems revealed that data collection practices are non-systematic and irregular, and the existing data, particularly pedestrian exposure to risk, is not sufficient for pedestrian safety analyses. Thus, a methodology was developed to estimate pedestrian exposure at CBD intersections and midblocks using existing data sources and a set of complimentary data collections. Pedestrian crash risk at CBD intersections and midblocks were evaluated, separately: during daytime hours, or alternatively called working hours, (7-18), and hours of darkness, or alternatively called non-working hours, (0-6 and 19-23). Findings showed that pedestrian crash risk is multi-factorial in nature. Different sets of factors were found to be associated with risk across different space-time frameworks. For intersections, the three most powerful predictors of pedestrian collision rate during daytime hours were the characteristics of land-use, road and public transport, respectively. Similarly, during hours of darkness, the rate was highly correlated with the characteristics of land-use and road. For midblocks, the most powerful predictor of the frequency of pedestrian crashes during daytime hours was public transport, followed by land-use and road characteristics, respectively. In contrast, midblock pedestrian collision rates during hours of darkness were mainly predicted by the length of the midblock, followed by land-use and public transport characteristics, respectively.Another key finding of the pedestrian crash risk analyses was that different measures of pedestrian exposure influence pedestrian crashes at intersections compared with midblocks. While traffic volume (Annual Average Daily Traffic (AADT)) played a significant role in developing pedestrian crash risk models at intersections, the product of "pedestrian road crossing counts" and AADT (PxAADT) was the influential pedestrian exposure measure in the midblocks daytime-hours risk model. Results of the pedestrian injury severity analyses also revealed a diverse set of factors associated with pedestrian injury severity for different space-time frameworks. The correlates of major pedestrian trauma at intersections were time of day, vehicle movement, pedestrian age, vehicle colour, and land-use and public transport characteristics. For midblocks, influential factors were time of day, the characteristics of land-use, and the interaction of day of week and speed zone.The injury severity data reported by the police for pedestrian crashes in the Melbourne CBD (2000-2009) was found to be not consistent with hospital data. Thus, using the police data can lead to misleading conclusions about pedestrian injury risk factors. Findings of this research provide evidence-based insight into the pedestrian safety problem in the Melbourne CBD and have implications for other concentrated urban areas. This knowledge can be applied by road safety researchers and practitioners to modify existing design practices to achieve a safer pedestrian environment and to facilitate the Victorian Government's strategic plan for a Safe System for all road users. In addition, six new Central Activity Districts and 26 principal activity centres are projected to be designed and implemented by 2030 in Melbourne. The outcomes of this research provide critical, new information to enhance the pedestrian safety design guidelines for these new developments.

This book was released on 2019 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, demand for active transportation modes such as walking and cycling has increased. While it is desirable to provide high levels of safety for these eco-friendly modes of travel, unfortunately, the overall percentage of pedestrian and bicycle fatalities, increased from 13% to 18% of total road crash fatalities in the last decade. In San Diego County, although the total number of pedestrian and cyclist fatalities decreased over the same period of time, a similar trend with a more drastic change is observed; the overall percentage of pedestrian and bicycle fatalities increased from 19.5% to 31.8%. Technological advancement in transportation has been creating new opportunities to explore and investigate new sources of data for the purpose of improving safety planning. This study aims to identify signalized intersections with the highest risk for walking and cycling within the City of San Diego, California, USA. Multiple data sources such as permanent pedestrian and bicycle counters, video cameras, and crash data were utilized. Data mining techniques and a new sampling strategy were adopted to demonstrate a holistic approach that can be applied to identify facilities with the highest need for improvement. Cluster analysis coupled with stratification was employed to select a representative sample of intersections for data collection and estimate annual average daily pedestrian and bicyclist (AADP and AADB). Additionally, the study quantified risk incorporating injury severity levels, the frequency of victims, distance crossed, and exposure into a single equation. It was found that not all intersections with the highest number of pedestrian and bicyclist victims were identified as high-risk after exposure and other factors such as crash severity were taken into account.
