Pedestrians at most of the downtown intersections in Dallas are finding the push-to-walk buttons don't do anything.
The Dallas Morning News reports that nearly all of the city's 200 traffic signals function on a pre-timed system. The push-to-walk buttons don't work how pedestrians expect them to because the signals change based on set time increments.
The assistant director of the Department of Street Services says the city doesn't need the buttons. He says the pre-timed signals are safer for pedestrians.
Dallas switched to the pre-timed system when the vehicle detectors of its old signals stopped working. The old system slowed traffic and prevented lights from changing regularly.
