Bike Injury Patterns

Bicycle injuries and fatalities are an increasing problem. The Pedestrian and Bicycle Information Center is a program of The University of North Carolina Highway Safety Research Center in cooperation with the Association of Pedestrian and Bicycle Professionals. It is funded by the U.S. Dept. of Transportation.
Statistics published by the Center reveal patterns of biking fatalities and injuries. Using 1999 data, there were 750 bicycling fatalities and 51,000 bicycling injuries resulting from traffic crashes in the United States. Bicyclist fatalities accounted for 2 percent of all traffic fatalities as well as 2 percent of all traffic injuries. The patterns were as follows:
Motorist turning or merging into the path of a bicyclist (12.1 percent of all crashes). Almost half (48.8 percent) of these crashes involved a motorist making a left turn in front of a bicyclist approaching from the opposite direction.
Motorist overtaking a bicyclist (8.6 percent of all crashes). Of these crashes, 23 percent appeared to involve a motorist who misjudged the space required to safely pass the bicyclist.
Bicyclist turning or merging into the path of a motorist (7.3 percent of all crashes). Within this category, 60 percent involved a bicyclist making a left turn in front of a motorist traveling in the same direction.
When the motorist and bicyclist were on initial crossing paths, the three most frequent categories of crashes were:
Motorist failed to yield right-of-way at a junction (21.7 percent of all crashes). Of these crashes, more than a third (37.3 percent) involved a motorist violating the sign or signal and drove into the crosswalk or intersection and struck the bicyclist.
Bicyclist failed to yield right-of-way at an intersection (16.8 percent of all crashes). Within this category, 38 percent involved a bicyclist who had stopped for a sign or flashing signal and then drove into the intersection and was struck by the motor vehicle.
Bicyclist failed to yield right-of-way at a midblock location (11.7 percent of all crashes). Almost half of these crashes (43.4 percent) involved a bicyclist riding out into the roadway from a residential driveway.
