Vulnerable road users have a disproportionate share of crash fatalities. And the commonly accepted safety improvements might reduce crash frequencies for drivers, but it doesn’t do it enough (and have enough impact on major injuries death) to overcome their complaints of slower traffic and less parking. If it did, America’s traffic safety numbers would look more like Western European countries. For example pedestrian bulb outs and daylighting reducing on-street parking while making pedestrians more visible. Bike lanes remove travel lanes or parking, making traffic slower. Lower speed limits make crashes more survivable, but slow down traffic. When used for safety (and not cash) speed and red light cameras increase safety, but make driving costlier.
