| Abstract | The Illinois Department of Transportation (IDOT) published the AASHTO Highway Safety Manual Illinois User Guide with Illinois Calibration Factor and Default Values in 2014. This book provides guidance on incorporating AASHTO Highway Safety Manual methods into Illinois roadway safety management practices. Also in 2014, IDOT published the Systemic Safety Improvements: Analysis, Guidelines and Procedures Guidebook, which enables IDOT to systemically analyze crash, roadway, and facility information, select countermeasures, and prioritize safety-related projects. This case study describes how IDOT staff use these two related guides to improve safety. |
