Traffic Light timings

The traffic light times for buses entering Princes Street from David Street are a joke. If a bus misses the lights which only lets 2 through at a time anyway, it's at least another 3 minutes before they change again, and that's if a tram doesn't come through to mess them up again. The traffic lights the full length of Princes Street need their timings adjusted, especially at peak times of the day to let buses and trams pass through quickly and avoiding unnecessary congestion.
