I'm going with your definition of "jumping the lights" because that's what I was taught many years ago. I'd also include "people who enter a controlled junction with no clear exit" since they end up beyond the red light without being able to move - that's the situation at our local supermarket. Normally end up with a bus in the bus lane and 3-4 cars sat in the junction across the pedestrian crossing on every light change at peak time.
