Warning! Traffic Lights Can Be Bad for Pedestrians
On low volume streets, traffic lights can actually make dangerous conditions even worse by encouraging speeding and increasing traffic. Philadelphia removed 400 traffic lights after an official study found that traffic lights increase the frequency and severity of crashes. Unfortunately, many community groups, uninformed and groping for any answer to their traffic problems, latch on to lights as their only hope. In many places, stop signs, speed humps and other traffic calming devices offer a better solution.
