Key Accomplishments

  • Increased the number and quality of local safety projects.
  • Developed local agency analysis capabilities on safety trends including development of charts and maps.
  • Aligned local safety efforts with the SHSP.

Because the fatal crash rate on non-State highways was higher than on State highways, Michigan recognized that additional tools were needed to support local safety planning and programming. The Local Technical Assistance Program (LTAP) developed a GIS-based integrated roadway management system to analyze and report on local roadway inventory, safety, and condition. The software’s safety module helps local practitioners conduct several analyses, including identifying trends in crash frequency and severity, determining segments eligible for the High-Risk Rural Roads funding program, and identifying intersections of concern in their jurisdictions. Crash report data are embedded in the software so users can easily access crash reports when conducting safety analysis. These new analysis capabilities result in projects targeted to locations with high rates of fatal and serious injury crashes. Previously, it was common for projects to be targeted at locations based on resident complaints. Development of standard data queries aligned with SHSP emphasis areas is underway.

The software also includes diagnostic tools to analyze crash patterns to identify locations where infrastructure improvements can reduce crash frequency and severity. Once problem areas are defined, users can follow built-in links to National Cooperative Highway Research Program safety documentation to identify promising countermeasures. MDOT-funded enhancements to the safety module and provides funding for the LTAP to offer the software and training at no cost to local agencies.

Since the establishment of the MDOT Local Safety Initiative in 2004, three dedicated staff have provided engineering support to local agencies by conducting local crash analysis using the software. Additionally, MDOT conducts field reviews of locations of interest with the local agency and provides suggestions for safety countermeasures. When staff conducts outreach to local agencies they provide information on the State’s SHSP to increase alignment of local activities with Statewide safety goals and strategies.

Results

More than one-half of counties have voluntarily sought support on safety data analysis, countermeasure development, and training from the local safety initiative. The local capacity for safety analysis has improved, and the number and quality of local safety projects has increased.
