Detecting Motorcyclists and Bicyclists at Intersections

摘要

According to the National Highway Traffic Safety Administration (NHTSA), the number of U.S. traffic fatalities in 2008 reached its lowest level since 1961. Despite an overall improvement in safety, however, motorcyclist deaths continued their 11-year increase, reaching 5,290 in 2008, accounting for 14 percent of all highway fatalities. Bicyclists, too, face disproportionate dangers on the Nation's roadways. Although bicycle trips accounted for less than 1 percent of all trips in 2008, bicycle riders represented 2 percent of all traffic fatalities.
