Safety Data and Analysis
|Project Description:||To develop reliable crash modification factors (CMFs) for new and innovative low-cost safety improvements that have not been proven. These CMFs are determined by conducting scientifically rigorous before-and-after evaluations at sites in the United States where these strategies are being implemented. This Transportation Pooled Fund (TPF) Study has 38 Department of Transportation State members, and provides a platform for State members to conduct peer exchange and technology transfer related to low-cost safety countermeasures. Also, this TPF determines high priority safety improvement needs through a balloting process in its annual technical advisory committee meeting.|
|Start Date:||January 1, 2005|
|End Date:||December 31, 2017|
|Goals:||The key project objectives are to develop reliable estimates of the effectiveness of the safety improvements that are identified as strategies in the National Cooperative Highway Research Program Report 500 Guides. These evaluations provide crash modification factors (CMFs) and benefit/cost (B/C) ratio for nationwide field applications of proven low-cost safety countermeasures.|
|Background Information:||The goal of this research is to develop reliable estimates of the effectiveness of the safety improvements that are identified as strategies in the National Cooperative Highway Research Program (NCHRP) Report 500 Guides. In 1998, the American Association of State Highway and Transportation Officials (AASHTO) approved its Strategic Highway Safety Plan, which was developed by the AASHTO Standing Committee for Highway Traffic Safety with the assistance of the Federal Highway Administration, the National Highway Traffic Safety Administration, and the Transportation Research Board Committee on Transportation Safety Management. The plan includes strategies in 22 key emphasis areas that affect highway safety. Each of the emphasis areas includes strategies and an outline of what is needed to implement each strategy. There are 22 available volumes of NCHRP Report 500: Guidance for Implementation of the AASHTO Strategic Highway Safety Plan, a series in which relevant information is assembled into single concise volumes, each pertaining to specific types of highway crashes (e.g., run-off-road, head-on) or contributing factors (e.g., aggressive driving). All volumes of the report are published and linked to the AASHTO Safety Plan Web site.|
|Test Methodology:||Empirical Bays statistical analysis for before-after studies.|
|Other Information:||The Federal Highway Administration’s Human Factors Laboratory was used for phase IV. The phase was completed and published.

|Expected Benefits:||The expected benefits are producing crash modification factors (CMFs) and benefit/cost (B/C) ratio analysis for nationwide application of low-cost safety countermeasures, enabling State and local highway agencies to make more cost-effective investment decisions. Also, it benefits the participating States by providing them a vehicle for conducting peer exchange and technology transfer where it concerns highway safety improvement installations. At the same time, 38 State members provide feedback to the Federal Highway Administration for their high- priority safety research needs through balloting process.|
