Traffic incidents remain all-too-common events on Kentucky’s roadways. They negatively impact the safety of the traveling public and emergency responders and cause significant traffic delays. Congestion associated with incidents can instigate secondary crashes, exacerbating safety risks and economic costs. Traffic incident management (TIM) provides an effective approach for managing highway incidents and reducing their occurrence and impacts. This report discusses the establishment of and methods of calculation for five TIM performance measures that can be used by the Kentucky Transportation Cabinet (KYTC) to improve incident response. The measures are: Roadway Clearance Time, Incident Clearance Time, Secondary Crashes, First Responder Vehicle Crashes, and Commercial Vehicle Crashes. Ongoing tracking and analysis of these metrics will aid the Cabinet in its efforts to comprehensively evaluate its TIM program and make necessary improvements. As part of this project, a fully interactive TIM dashboard was developed using the Microsoft Power BI platform. Dashboard users can apply spatial and temporal filters to identify trends at the state, district, and county level. The dashboard also supports dynamic visualization tools such as cards, charts, and maps. With the TIM dashboard in place, KYTC personnel, as well as staff at other transportation agencies, can identify the strengths and weakness of their incident management strategies and revise practices accordingly.
