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.
