This report analyzes the problem of pedalcyclist crashes in the United States to support the development and assessment of effective pedalcyclist crash avoidance systems as part of the U.S. Department of Transportation's Intelligent Vehicle Initiative. This study describes pre-crash scenarios most prevalent in pedalcyclist crashes by identifying vehicle maneuvers and pedalcyclist action combinations. This analysis is based on data from the 1995-1998 National Automotive Sampling System/General Estimates System and Fatality Analysis Reporting System databases. In 1998, about 58,000 pedalcyclist crashes, or 0.9%of all police-reported crashes, occurred in the United States, resulting in 760 fatal crashes, or 2.1%of all fatal motor vehicle crashes that year. Pedalcyclist crashes were broken down into 8 pre-crash scenarios. Most pedalcyclist-involved crashes occurred on straight non-hillcrest roadways and on the roadway. Almost 75%of the crashes occurred on roadways with speed limits between 25 mph and 35 mph. Nearly 12%of the drivers and over 50%of the pedalcyclist were under 20 years old. 72%of the pedalcyclist crash population fell into the 5-29 year old age range. |
