This page contains information about research projects that are currently underway. Monthly reports are in PDF format.

  • Project Description:
  • This project will calibrate the crash prediction models in 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 objectives of this project are:
  1. Calibrating the safety performance functions (SPFs) for three facility types based on their safety performance in Idaho using the state's crash data. These facility types include two-lane roads, rural multi-lane roads, and urban and suburban arterials.
  2. Evaluating crash severity distribution methods.
  3. Preparing a report summarizing findings and recommendations.
