The Community Pedestrian Bicycle Safety Training (CPBST) program is a collaborative project between UC Berkeley Safe Transportation Research and Education Center (SafeTREC) and California Walks (Cal Walks) that seeks to assist communities with three goals:

Identifying and better understanding their local transportation safety needs; Developing and strengthening local partnerships between various stakeholders in their community; and Generating a community-specific action plan for improving the safety of active transportation in their area.

These objectives are pursued through...

The Community Pedestrian and Bicycle Safety Training Program (CPBST) is a collaborative effort between the Safe Transportation Research and Education Center (SafeTREC) at the University of California Berkeley and California Walks (Cal Walks), established in 2009, with funding from the California Office of Traffic Safety. Its main objective is to promote pedestrian and bicycle safety by educating...

Pedestrian Crash Risk on Boundary Roadways University Campus Case Study

Schneider, Robert J.
Grembek, Offer
Braughton, Matthew
2013

Prominent pedestrian trip attractors, such as college campuses and major urban parks, are often surrounded by roadways with high volumes of motor vehicle traffic. Although many pedestrians cross busy boundary roadways, relatively little is known about the pedestrian crash risk along these types of facilities. This study quantifies pedestrian crash risk at roadway intersections on the boundary of the University of California, Berkeley, campus during typical spring and fall semester weekdays. Manual pedestrian counts were extrapolated with data from three automated counter locations to...

Pre-hospital Care of Road Traffic Injuries in Chiang Mai, Thailand

In many developing countries, transportation infrastructure development lags behind the tremendous growth in motorization. Road traffic injuries cause enormous morbidity and mortality worldwide, placing heavy burdens on global and national economies. Underdeveloped transportation infrastructures critical to traffic safety include roadway improvement, occupant protection laws, traffic law enforcement, and emergency medical services (EMS). Highlighting one important aspect of lagging infrastructure, this article focuses on emergency medical services. This research study offers a descriptive...

Impact of Pedestrian Presence on Movement of Left-Turning Vehicles: Method, Preliminary Results & Possible Use in Intersection Decision Support

2004

Warning systems are being developed for left-turning vehicles at intersections where protected left-turns are not warranted or cannot be provided, based on limitations of right of way or intersection capacity. These are meant to provide warnings to left-turning vehicles of vehicles approaching from the opposite direction, when the time to turn may be deemed unsafe. To implement these warning systems, it is necessary to estimate in near real time, the probability of conflict between the two approaching vehicles. A study is being conducted with the help of video and radar at various...

Alcohol, Stress-Related Factors, and Short-Term Absenteeism Among Urban Transit Operators

Fisher, June M.
2005

Transit operators, relative to workers in many other occupations, experience high levels of work-related stress, as documented through neuroendocrine elevations on the job vis-à-vis resting states (J Occup Health Psychol. 1998;3:122–129). Previous research suggests that self-reported job stress is associated with higher levels of alcohol consumption among transit operators (Alcohol Clin Exp Res. 2000;24:1011–1019) and with absenteeism (Working Environment for Local...

The overall IDS research plan was constructed to realize, in slightly more than three years, the requirements, tradeoffs assessment, and technology investigations necessary to define an IDS. Toward the end of the project we will combine our understanding of the problem definition, IDS technologies and our integration experience with a standard Caltrans intersection (with advanced controller) and design a deployable IDS demonstration that can be field tested.
