How Pleasanton Traffic Signals Make the City Green

Original post made by Stacey on Nov 13, 2009

Here's a bit of fancy...

Jerry Brown says Pleasanton contributes to global warming because we have too many jobs compared to places to live and this translates into more cars on the road. Ah, but BMW says our synchronized traffic signals lead to increases in fuel efficiency and that means we're actually combating global warming!

"In its initial research, the group studied so-called Green Waves—a minimum of four signals in sequence that can be synchronized for better traffic flow. Simply by changing the timing of traffic lights on a test stretch of roadway in Munich, the engineers were able to nearly double the fuel efficiency of a BMW 530d test vehicle—from 22 mpg to 42 mpg. That being an idealized situation, the company expects an overall 10 to 15 percent decrease in urban fuel consumption due to smart traffic signaling."

Yeah but lights are also set up here in town to stop traffic flow. It is a weird cat and mouse game where the City wants to promote traffic flow and yet reduce cut through traffic. Synch all the lights = more cut through traffic, more cars, more local pollution. Have all the lights unsyched = cars ideling at lights, more traffic, more local pollution. They have been trying to find the middle ground for years.
