Pedestrians are the second largest category of motor vehicle deaths, after occupants. Although the number of pedestrian deaths has decreased dramatically, these still account for 12 percent of motor vehicle deaths. The problem is worst among the elderly.
Pedestrian deaths are principally an urban problem.
Many pedestrians are killed at crosswalks, sidewalks, median strips, and traffic islands. Physical separations like overpasses, underpasses, and barriers can reduce the problem. Warning signs and pavement markings at intersections also can be effective. And because there's a higher ratio of pedestrian deaths to injuries where speed limits are higher, lowering the limits could reduce pedestrian deaths. Vehicle factors count, too, because the most serious injuries often result from pedestrians being thrown onto the hoods, windshields, or tops of vehicles.
