Smart Cars have a lot of your idea (written description) built into them.

The Smart ForTwo manual tells you to shut down the engine if you will sit parked at a traffic light for more than 10 seconds. I coast up to lights when I see them turn red all the time. :o) I was in traffic yesterday on a down hill slope and left the engine off in traffic for a long time. :o)
