Legit question (not trying to troll) but is the data for pedestrian/cyclist safety based purely on accidents at lights or specific to red light behavior. I ask because Cambridge has a ton of anti-car intersection where the pedestrian lights are only green when the traffic lights are also green, but the only direction for traffic is a turn (aka you are forcing cars into pedestrians due to lights). I'd be curious what the effects of safety are with these setups as well
