Abstract This report methodology is prepared by the Michigan Department of Transportation (MDOT), to report on all public roads in the state. The methodology is based on the guidance offered in the April 10, 2006 FHWA 5% Reporting Guidance Document and the subsequent HSIP related web conference held June 20, 2006. In Michigan, there are approximately 122,000 miles of public roads, of which 92 percent are under local jurisdiction. MDOT does not have a consistent methodology to conduct statewide surveillance of the road network due to lack of data on locally owned roads. As MDOT does not have jurisdiction over local roads, it has not been our practice to develop a statewide list of hazardous locations due to the availability of resources to address locations of concern, and the competing priorities of local units of government. MDOT is in the process of developing new system surveillance tools which will allow review of the entire statewide network. For the purposes of this report separate methods were developed for MDOT and locally owned roads and makes best use of the available information with the objective to identify intersections and segments with the most severe safety needs. In Michigan a statewide GIS referencing system is utilized on which all crashes, on all roads, are referenced to. We have good crash data, located such that we can conduct a statewide analysis to determine the most hazardous locations. Michigan crash data contains information on the severity of the crash, whether it is a fatal injury (K), incapacitating injury (A), non-incapacitating injury (B), possible injury (C) or property damage only (O) crash.
