How Pleasanton Traffic Signals Make the City Green
Original post made by Stacey on Nov 13, 2009
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 Wavesa 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 vehiclefrom 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."
