IssueApplication of the Highway Safety Manual (HSM) and related safety data tools. Key Accomplishments“The advantage of employing IHSDM on this project was the opportunity to perform a detailed and simultaneous review within the corridor on a variety of critical elements (that is, traffic operations, geometry, safety) to isolate potential problem areas and allow development of strategic mitigation strategies.” – Bob Beckman, Project Manager
ResultsThe development of a more advanced safety analysis for the Corridor Study that was data-driven and integrated into the Statewide Transportation Improvement Program (STIP). Benefits
