The correct reaction is to fix the root cause of the problem.
Have the various GPS navigation services generate flow-through rate reports for every intersection at different times of the day and use those as a sample to actually program light cycles for traffic volume.
Also while we're at it, make it so that the lights actually sync up and so that out of flow merges (lefts/rights/etc) only need to speed up a little to hit the next light wave.

Don't the traffic lights already know the flow rate through their intersections?
- Piskvorrr 7y agoNo. For the most part, they're programmed in a fixed cycle from static estimates (usually made once and unchanged since who-knows-when); the more advanced types allow for skipping through phases if there's no (car) traffic detected for them. Actual traffic measuring and dynamic control is rare.
- Johnny555 7y agoThen those lights aren't going to take a feed from Waze to adjust themselves anyway. My point is that if analyzing traffic flows would let cities adjust light cycles to manage traffic, they could already do it -- they don't need a data feed from Waze.
