This is the case here - many pedestrian crossings aren't guarded by lights but by stripes on the road. There is one beside my work which is incredibly poorly timed. It turns green for pedestrians about 10 seconds after a traffic light goes green for cars further down the road - where it takes about 9 seconds for cars to accelerate to ~40kph and reach the crossing. I've personally seen one person get hit (driver sped off, obviously) and countless near-misses because of this, and I've no doubt it will get someone killed one day.
