While research and empirical evidence have shown positive safety and operational benefits associated with good access management practices, it can be challenging for transportation agencies to implement access management strategies on the basis of safety performance without methods and tools to quantify the safety performance of alternatives.
The TRB National Cooperative Highway Research Program's pre-publication draft of NCHRP Research Report 974: Application of Crash Modification Factors for Access Management, Volume 1: Practitioner’s Guide presents methods to help transportation planners, designers, and traffic engineers quantify the safety impacts of access management strategies and make more informed access-related decisions on urban and suburban arterials.
Supplementary to the report is the pre-publication draft of NCHRP Research Report 974: Application of Crash Modification Factors for Access Management, Volume 2: Research Overview and a summary presentation for the two volumes.
