15:00 could be the switch to rush-hour signalling. I know where I live it screws up turn-lights and pedestrian crossing lights. I've seen turn lanes getting a single car through at every light change, it's gotten so bad that it clogs up one of the through-lanes. Similarly there's rarely a single pedestrian at a crossing, and I've been forced to J-walk because the pedestrian crossing hasn't come on for several light changes.
