Grade Crossing of LRT at Signalized Intersections

This paper describes how the rapid growth in the level of traffic has led to increasing congestion, particularly in urban areas. Therefore, a growing market has developed for the quality of public transport systems, and light rail transit (LRT) systems. The ability to operate at-grade, interfacing with traffic and pedestrians, is an important characteristic of LRT. It can reduce the cost of construction, improve access to important trip generators, and enable rail development to be justified in corridors where more costly construction may not be warranted. However, engineers and planners designing at-grade LRT typically are faced with the challenge of balancing two conflicting objectives. On the one hand, the transit company expects to receive full priority at all at-grade crossings in order to achieve minimum travel time. On the other hand, the authority having jurisdiction over the arterial on which the LRT runs expects to maintain normal intersection operations so that peak hour vehicle traffic delays are not worsened.
