Extension of Safety Assessment Tool for Construction Work Zone Phasing Plans

The objective of this project is to extend the previously developed safety assessment tool to include other facilities such as arterials, signalized intersections, multi-lane highways, and ramps. The research approach will include the collection and analysis of work zone and crash data from Midwestern states for different construction phasing alternatives. Specifically, data will be obtained from one or more of the Smart Work Zone Deployment Initiative (SWZDI) states- Kansas, Iowa, Wisconsin, Missouri, and Nebraska. The project deliverables will include an enhanced spreadsheet tool to help decision makers evaluate the safety risks of different construction phasing alternatives and lane closure scenarios. The current tool developed in a previous SWZDI project has received accolades from the SWZDI states, including Kansas and Missouri, for its ease of use and accuracy. Thus, enhanced tool will build upon the current tool and add more facility types to it. Attainment of the project objective will help to fill gaps in existing knowledge and provide transportation practitioners with a valuable tool to assist them in the evaluation of the safety impacts of construction work zones for different alternatives.
