MissionThe 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 CSTSPTraffic 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 Portlands 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. Monseres faculty position.

Portland States RolePSU, through the ITS Lab faculty and staff, provides leadership, expertise, research evaluation design, data collection, and statistical expertise to the program. Portland States role in this project includes: 1) Serving as technical advisor to each of the CSTSPs 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.

Empirical Comparison of German and U.S. Traffic Sensor Data and Impact on Driver Assistance SystemsSteven Hansen and Dr. Robert L. Bertini, Portland State Universitywww.its.pdx.eduCommunity and School Traffic Safety PartnershipCity of Portland and Portland State UniversityResearch Example: Photo RadarUsing 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. www.its.pdx.eduCSTSP Program Areas3 Es and RAEPhoto Radar and Red Light EnforcementSeverity Index of Disregard Traffic SignalsPhoto Radar EffectivenessDUII Crash CharacteristicsSafe Routes to SchoolPedestrian/Bicycle Safety18%DUII5%Occupant Protection3%Red Light Running 12%Speeding24%Safe Routes to School34%Research and Evaluation 4% Enforcement38%Engineering38%Education20%Research and Evaluation4%Performance Measure Plan report-A key focus is to evaluate performance measures in SAFE Corridors and in each of Portlands NeighborhoodsPDOT developed the Pedestrian and Bicycle Opportunity Analysis based on crash data, service request history, and input from the pedestrian and bicycle communityPresentation at the ITE Quad Conference and CUPUM PaperSupport PDOT on the Pedestrian and Bicycle Opportunity AnalysisPhoto Radar Pre/PostMinor streetOther arterialPrimary arterialSecondary arterialPortland Crashes Per Mile Per Year2.0811.3115.7927.02
