Report on strategies to reduce pedestrian and bicycle injuries
The California Department of Transportation (CalTrans) has released a report that explores the development of methods for identifying sites where there is potential for significant reductions in pedestrian and bicyclist injuries. The report, titled “Strategies for Reducing Pedestrian and Bicyclist Injury at the Corridor Level,” uses data from 1998 to 2007 along a16.5-mile section of San Pablo Avenue (SR 123) in the San Francisco East Bay area. The report includes a framework for conducting benefit-cost analyses and a prototype training protocol for conducting analyses of pedestrian and bicyclist safety in a corridor or network. The guiding principle is that sites with the most potential for reducing injury are those where the most injuries can be prevented per dollar spent. Everything else being equal, these sites are also the ones with the highest expected number of injuries if nothing is done. Prior history is typically used to make this estimate, but this may not be sufficient, especially if the underlying rates are low.
