Ensuring a coordinated response to highway crashes and other incidents is vital to protecting public safety, keeping traffic moving, and reducing environmental impacts. The TRB National Cooperative Highway Research Program's NCHRP Research Report 981: Guidelines for Quantifying Benefits of Traffic Incident Management Strategies aims to offer guidance on Traffic Incident Management (TIM) programs, which can vary widely and may have different goals, guidelines, and methods applicable under a variety of data scenarios. Supplemental to the report is NCHRP Web-Only Document 301: Development of Guidelines on Quantifying Benefits of Traffic Incident Management Strategies, an Implementation Plan, and a Summary Presentation.
