Use Waze information to Control Traffic Lights
Since I'm a long time user of Waze and Google Maps, I was wondering if Alphabet Inc. has considered designing a smart system that would use the data transmitted by Waze clients to program traffic lights.
From the research I've done, the actual smart systems in advanced cities are based on sensors and cameras placed at the intersections which makes this solution very expensive and thus not attractive to third world country cities. There's even a proposal using RFIDs in vehicles.
I am sure that city governments would promote vigorously the use of these apps and embrace a solution that wouldn't require rewiring of all the traffic lights.
The system can be so intelligent that it could predict the incoming traffic from miles away using the routes suggested by Waze and chosen by the drivers.

Give every stop light an IP address. Install traffic sensors on the underside of each stop light. Along with the traffic sensors & data feeds from Waze and Google Maps, all traffic lights could be handled by Waze. This will reduce wait times and gas consumption way beyond government fuel mandates. Call this Awazing Traffic Lights
