Calibrating the Highway Safety Manual Crash Prediction Models for Idaho's Highways
This project will calibrate the crash prediction models in the American Association of State Highway and Transportation's Officials (AASHTO's) Highway Safety Manual (HSM) to Idaho conditions to more accurately assess the expected safety performance of different highway segments in Idaho and to assess the safety impact of different design alternatives. The crash prediction models used are for three highway facility types: rural two-lane two-way roads, rural multilane roads, and urban and suburban arterial roads. This project will calibrate the safety performance functions (SPFs) for all three facility types based on their safety performance in Idaho using the state's crash data.
