New traffic signals make it safer for pedestrians

A new kind of traffic signal in Delaware, the High-intensity Activated Cross Walk, or HAWK, became active Friday and will make crossing Delaware 72 safer for students beginning this semester, state transportation officials say.

Delaware joins a growing number of states and cities around the country, including Georgia, Minnesota, Virginia and Arizona [but not Maryland], with HAWK signals that allow people to cross a busy road, either at an intersection without a standard traffic signal or in the middle of a long stretch of road.

The solid red light is followed by flashing red lights, allowing drivers to proceed if the crosswalk is clear. The signal then goes dark again and traffic flows freely. Researchers with the Texas Transportation Institute at Texas A&M University last year compared before-and-after accident data at 21 HAWK sites in Tucson and found a 13% to 29% reduction in all crashes and a 50% drop in pedestrian accidents.
