• Abstract:
  Rail lines present two major challenges to the ; roadways they intersect: potential for collisions ; and increased congestion. In addition, congestion ; can contribute collision hazards when drivers are ; impatient or vehicles are prevented from clearing ; the tracks in a timely manner. Congestion has ; other consequences, as well, including impacts on ; emergency services and increased pollution from ; hundreds of idling automobiles. ; To improve safety and mobility of railroad ; crossings, the Manual on Uniform Traffic Control ; Devices (Federal Highway Administration) suggests ; implementing a preemption plan for signalized ; intersections within 200 feet of the crossing, ; which can help clear vehicles from the tracks ; before a train’s arrival. Preemption introduces ; new elements into the overall management of a ; roadway network, especially during peak traffic ; periods. Therefore, it is necessary to utilize ; modern traffic control systems and develop ; effective traffic control strategies.
