HAWK.

As an almost Traffic Engineer and full blown road geek, I’m a fan of videos by Road Guy Rob. This week Rob talks about HAWK signals. These are yellow/red signals at pedestrian crosswalks that are activated almost immediately when a pedestrian pushes the button. It flashes yellow as a warning to motorists, then solid yellow, then solid red. After a few seconds it switches to flashing red, so if the pedestrian is no longer on your side of the road, a motorist can continue through the flashing red, which is treated like a stop sign.

I’ve been a fan of HAWK installations since I first read about them a number of years ago. They’re pretty neat and they really help keep pedestrians safe. What I didn’t know is they were invented right here in Tucson.

Road Guy Rob explains it quite well.
