"Presence Sensors" Save Bicyclists By Controlling Traffic Lights
The system, called "The Interceptor", is currently being tested in Pleasanton, California.
Jessica Mulholland of Governing Magazine talked with Pleasanton Senior Transportation Engineer Joshua Pack:
"When the sensor detects a bicycle, it triggers the timing of traffic lights one way, and when it detects only cars, it triggers a different timing scheme. The better pacing of green lights provides a safer crossing," Pack explained.
Pack likes the system, but is concerned about increasing delays when his city's traffic is primarily automobiles.
