The HSIP Manual describes the overall Highway Safety Improvement Program and provides a roadway safety management process which focuses on results by emphasizing a data-driven, strategic approach to improving highway safety through infrastructure-related improvements. Current laws and regulations, new and emerging technologies, and noteworthy practices are presented for each of the HSIP’s four basic steps – analyze data, identify potential countermeasures, prioritize and select projects, and determine project or program effectiveness.

This comprehensive highway reference is intended for state and local transportation safety practitioners working on HSIPs and safety projects.
