COLLISION TRENDS
There is no one-size-fits all solution to the issue of traffic collisions. However, a study of best practices helped us identify proven solutions to address collision types that often result in death or serious injury. For example, left-turn restrictions may be explored in locations where those turns have caused collisions. A speed-limit reduction may be more appropriate on streets where children walk to school. Warning devices, such as a“ Stop Here for Pedestrians” sign and flashing beacons, can be useful to guide drivers at complex intersections. High-visibility bicycle treatments at major intersections on the bicycle network can help clearly delineate street space and provide organization that avoids conflict between people driving and people bicycling. 8 These pairings, called countermeasures in the transportation field, inform project development by helping us evaluate what will be most effective at different locations with varying conditions.
COLLISION TRENDS
70 percent of fatal or serious pedestrian and bicycle collisions involved male drivers.
Pedestrian collisions on arterial streets are seven times more deadly than collisions on non-arterial streets.
Turning movements at traffic signals account for about one-fifth of fatal or severe pedestrian and bicycle collisions.
Left turns( 12 percent) account for about twice as many collisions as right turns( 6.2 percent).
