Approximately one out of six highway fatalities in the United States is a bicyclist or pedestrian each year. Estimates for 1995 indicate that 61,000 bicyclists were injured and 830 were killed in traffic crashes. These crashes can be classified or "typed" by their precipitating actions, predisposing factors, and characteristic populations and/or location that can be targeted for intervention.
The objective of this project is to develop revised operational analysis procedures for transportation facilities with pedestrian and bicyclist users. This document describes the effects of pedestrians and bicyclists on the capacity of signalized intersections. These procedures augment the existing Highway Capacity Manual signalized intersection Level of Service procedures for locations with substantial pedestrian and/or bicycle traffic conflicting with vehicular turning movements.

This report is a reference document on safety for use by transportation planners. It serves as a companion to the National Cooperative Highway Research Program’s (NCHRP) Report 500 Guidance for Implementation of the American Association of State Highway and Transportation Officials (AASHTO) Strategic Highway Safety Plan.

In January 2012, FHWA issued a “Guidance Memorandum on Promoting the Implementation of Proven Safety Countermeasures”. This guidance takes into consideration the latest safety research to advance a group of countermeasures that have shown great effectiveness in improving safety. Safety practitioners are encouraged to consider this set of countermeasures that are research-proven, but not widely applied on a national basis.
The Pedestrian Safety Guide and Countermeasure Selection System is intended to provide practitioners with the latest information available for improving the safety and mobility of those who walk. The online tools provide the user with a list of possible engineering, education, or enforcement treatments to improve pedestrian safety and/or mobility based on user input about a specific location.

The proportion of the United States population age 65 and over will increase significantly in the coming decades. The effects of aging on people as drivers and pedestrians are highly individual. Challenges that may impact people as they age include declining vision, decreased flexibility and psychomotor performance, and changes in perceptual and cognitive performance. Design practices that explicitly recognize these changes will better serve this growing segment of the nation's population.
