Development of Crash Modification Factors for Speed Management of Traffic Signal Progression
| 项目名称： | Development of Crash Modification Factors for Speed Management of Traffic Signal Progression |
| 摘要： | The proposed research project aims to investigate the function and impacts of traffic signal progression on pedestrian crash frequencies and severities on Florida urban arterials, develop Crash Modification Factors/Functions (CMFs) for speed management via traffic signal progression, and provide guidelines on implementation of effective and adequate traffic signal progression strategies to manage vehicle speeds to reduce pedestrian crashes. Research objectives include: (1) Address traffic signal progression-related factors contributing to or alleviating pedestrian crashes and injuries, such as signal timing parameters (cycle length, phases, offset, etc.), roadway characteristics (type, lane configuration, speed limit, etc.), and others. (2) Investigate the influence of traffic signal progression on vehicle speed, which is a surrogate safety measure related to pedestrian crash and injuries, on urban arterials. (3) Develop CMFs to quantify the impacts of traffic signal progression on pedestrian crash frequency by injury severity. (4) Develop guidelines and recommendations to apply traffic signal control strategies on urban arterials for improving pedestrian safety and keeping vehicle mobility. The research will investigate the influence of traffic signal progression on vehicle speed and develop CMFs to quantify impacts of traffic signal progression on pedestrian injuries and fatalities on Florida urban arterials. The guideline developed under this research can provide Florida Department of Transportation (FDOT) and local transportation agencies the tool to effectively and adequately implement traffic signal progression strategies to reduce pedestrian crashes and injuries and also maintain vehicle mobility. |
