Search: Shoulder Treatments: Crash Modification Factors Clearinghouse

A crash modification factor (CMF) is a multiplicative factor used to compute the expected number of crashes after implementing a given countermeasure at a specific site. The Crash Modification Factors Clearinghouse houses a Web-based database of CMFs along with supporting documentation to help transportation engineers identify the most appropriate countermeasure for their safety needs. Using this site, you can search to find CMFs or submit your own CMFs to be included in the clearinghouse.

n/a: Making Local and Rural Roads Safer for Pedestrians and Bicycles

There are several enhancements that can be introduced to improve safety for pedestrians and bicyclists. The safety treatments shown in the table below can be employed to improve pedestrian and bicycle safety at intersections in particular. The table also shows the associated crash modification factor (CMF) or crash reduction, the safety issue addressed, and the typical cost of implementation.

Pg 29-61: PedSafe Countermeasures San FransicoPhase 2 Final Report

This report presents the methods and key findings from San Francisco PedSafe, a comprehensive pedestrian safety planning and engineering project. It is one of three such projects in the nation funded by the Federal Highway Administration (FHWA) to evaluate:
In Phase I: The effectiveness of a pedestrian safety plan targeted to higher-injury areas;
In Phase II: The implementation of a range of mostly low-to-moderate-cost, innovative safety improvements.
