Interesting concept. Sequenced lights timed to the speed limits would accomplish the same thing.

They do that plenty here in Texas. I have heard that it is even against state law, but whatever.

Using red lights to regulate, slow down, and even stop traffic is common.

When I was in college, we "discovered" that the lights on the main roads were timed - to about 10mph over the speed limit.

It's almost like the cities were encouraging you to speed. Surely, they'd never do that. It's all about safety, not revenue...

Sequenced lights timed to the speed limits would accomplish the same thing.

I think they work at other speeds too.

Speed sensors cost more. So the companies which manage the revenue enforcement systems push them.

Bad concept, imho. It would be much better to use these detectors to sync up the green lights with the flow of traffic, to keep everything running smoothly. Instead, they are going to do the opposite and clog up their streets even more.
