Other identified contributing factors were the high local population density that leads to more pedestrian and vehicular traffic around the tracks, diverse varied socio-economic community around the line that creates literacy and language difficulties for public education campaigns, driver frustration due to the slow traffic speeds around the line that leads to more risk taking behavior, and the shared right-of-way with freight traffic in the fastest running section from Washington station to Willow station, where trains operate at a maximum of 55 mph between stations.
