Specifications include, but are not limited to: CMAP is undertaking a “Speed Data Project” that will look to improve traffic safety through analysis of speed patterns from connected vehicles. This data will be cross-referenced with other pertinent information including crash location, time of day, detailed crash data, land use, road configurations, directional hourly traffic volumes, and weather events. This project will create safety metrics for roads and intersections across the seven county CMAP region which will be shared with our regional partners. The final analysis will identify patterns of speed metrics which are associated with increased crashes or increased crash injury severity. Additionally, the road geometries and configurations with lower crash rates will be identified. Based on the findings, CMAP will develop recommendations for potential improvements for high crash locations with identified speed profile issues. These recommendations include strategies such as traffic calming geometries, speed limit changes, appropriate enforcement, improved traveler information, and education. The techniques to evaluate the waypoint data to create speed profiles is left to the applicant to determine. Innovation is expected for this project as it involves a great deal of exploratory analysis.
