Deplll'tment ot Commerce - National TechnlcaJ Information Service c Spnngfield, Virginia 22161 FOREWORD Pedestrians and bicyclists comprise more than 14 percent ofall highway fatalities each year. In some large urban areas, pedestrians account for 50 percent oftraffic fatalities. Estimates for 1994 indicate that 150,000 pedestrians and bicyclists were injured in traffic crashes, and many injuries are not reported to recordkeeping authorities. The National Highway Traffic Safety Administration (NHTSA) developed a system of "typing" pedestrian and bicyclists crashes, defined by specific sequences ofevents. Each crash type has precipitating actions, predisposing factors, and characteristic populations and/or locations that can be targeted for intervention. The research documented in this report is the result ofthe application ofNHTSA's crash typology to a sample of5,000 pedestrian and 3,000 bicycle-motor vehicle crashes from five states with the purpose of refining and updating the crash type distributions. Particular attention was given to roadway and locational factors in order to identify situations where engineering and/or educational or regulatory countermeasures might be effectively implemented to reduce the frequency ofthe crashes. The information contained in this report should be of interest to State and local bicycle and pedestrian coordinators, transportation planners, and transportation engineers involved in safety and risk management. Other interested parties include those in education, enforcement, and the .medical profession. ~?@aW . ~~rey F.

Abstract ""'~4'The purpose of this research was to apply the basic NHTSA'pedestrian and bicyclist typologies to a sample of recent crashes and to refine and update the crash type distributions with particular attention to roadway and locational factors. Five thousand pedestrian- and 3,000 bicycle-motor vehicle crashes were coded in a population-based sample drawn from the States of California, Florida, Maryland, Minnesota, North Carolina, and Utah. Nearly a third of the pedes trians were struck at or near (within 16 m (50 ft) of an intersection. Midblock events were the second major pedestrian crash type grouping, representing over a fourth (26 percent) of all crashes« _The bicycle-motor vehicle crash types distributed as: (1) parallel paths - 36 percent, (2) crossing paths - 57' percent, and (3) specific circumstances - 6 percent. Most frequent parallel path crashes were motorist turn/merge into bicyclist's path (34.4 percent) of all parallel path crashes), motorist' over- taking (24.2 percent), and bicyclist tuIn/merge into motorist's path (20.6 percent)...Most frequent crossing path crashes were motorist failed to yield (37.7 percent of crossing path crashes), bicyclist failed to yield at an intersection (29.1 percent), and bicyclist failed to yield midblock (20.5 percent). Future safety considerations should be systemwide and include an examination of .intersections and other junctions, well designed facilities, and increased awareness of pedestrians and bicyclists by motor vehicle drivers. 17.
