1. Community and School Traffic Safety PartnershipCity of Portland and Portland State University Mission The mission of the CSTSP is to improve traffic safety for all modes; to create a conducive environment that supports increased walking, biking, taking transit, and responsible motorist behavior; and to enhance neighborhood livability by implementing strategic, collaborative, and sustainable traffic safety improvements. About the CSTSP Traffic safety strongly impacts the overall health, livability and mobility in our urban areas. In the United States, there were approximately 42,000 highway-related fatalities a year - nearly forty percent occurring in cities. In early 2003, the City of Portland Office of Transportation (PDOT) launched the Community and School Traffic Safety Partnership (CSTSP). The CSTSP is a response to the strong public demand for services that protect neighborhoods from the negative impacts of traffic and provide a safe environment for all modes of travel. It is a community-based, coalition-led effort to improve Portland’s traffic safety. Early in the development of the program, PDOT asked faculty experts in the ITS Lab to be involved on the CSTSP team. This unique partnership helps support Dr. Monsere’s faculty position. Portland State’s Role PSU, through the ITS Lab faculty and staff, provides leadership, expertise, research evaluation design, data collection, and statistical expertise to the program. Portland State’s role in this project includes: 1) Serving as technical advisor to each of the CSTSP’s three focus areas (reducing driver error, pedestrian and bicycle safety, and safe routes to school); 2) Developing the strategic action plan for reducing DUII crashes and more effective enforcement via the Strategic and Focused Enforcement and 3) Developing and recommending performance measures for the program.

Photo Radar and Red Light Enforcement Safe Routes to School Empirical Comparison of German and U.S. Traffic Sensor Data and Impact on Driver Assistance Systems Steven Hansen and Dr. Robert L. Bertini, Portland State University Research Example: Photo Radar Using advanced spatial analysis techniques, we have studied a number of safety issues for the CSTSP. The figure shows the relationship of mobile photo radar deployments and speed-related crashes. The color shades in A) are the exposure of vehicles at the neighborhood level to the photo radar and B) shows the number of speed-related crashes, while in C) represents the combination of these with the height being the number of speed-related crashes. It is clear from the figure some neighborhoods have experienced high levels of speed-related crashes even though the amount of exposure was high, perhaps indicating resources are being deployed correctly. In the lower figure, the number of alcohol-involved crash density was mapped over establishments that serve alcohol, showing a strong correlation.
