A pedestrian struck by a motor vehicle at 20 mph has more than an 80% chance of surviving. Conversely, if hit at 32mph or greater, a pedestrian has an 80% or greater chance of dying. Therefore, USDOT should set 2 specific goals:
1.Encouraging/mandating states to establish 20-25mph speed limits on urban or thickly settled streets.
2.Revising AASHTO's design speed criteria downward to create slower streets.
