Waze doesn’t yet provide public and mass transport routing like through metro or railways. If it happens in the future, we will surely provide those features. However, we have added a lot of metro stations as landmarks, and some railway lines and metro lines to account for a few errors that have shown up on the map. We can’t do much more than that at the moment, I’m afraid.
Traffic lights are not to be added to the map. Each junction incurs a time penalty for the route, and each segment records the average speed of the vehicles going through them so that accounts for traffic slowing down and stopping at traffic lights.
