Wrong-Way Driving Detection System

Publication Year:

From 2004-2014, 91 people were killed in wrong-way crashes across Arizona. In the two years 2015 and 2016, the number of serious injuries and fatalities due to wrong-way drivers more than doubled, from 16 to 37, and amplified media attention brought new public concern to the issue. The crashes were following patterns—75 percent were occurring at night, most collisions occurred in left lanes between the hours of 10 P.M. and 3 A.M., and about 75 percent of the drivers were impaired. Highway safety officials realized more had to be done to reduce the risk associated with wrong-way drivers.
