ANALYSIS OF LIGHT RAIL VEHICLE CLEARANCE TIME AT INTERSECTIONS

The intent of this study is to determine the amount of intersection disruption created by the implementation of light rail transit (LRT) through intersections with automobile traffic. The measure for determining intersection disruption is the LRT clearance time, which is the sum of time consumed by the actual presence of an LRT vehicle in the intersection and the time required before and after LRT arrival to prepare the intersection. Clearance time is affected by several factors that have been categorized as LRT vehicle operating characteristics, geometric layout of the intersection, and the traffic control method implemented. Several equations have been developed, with these factors as variables, to determine the LRT clearance time created by various operating conditions. In addition, several graphs show the ranges of clearance time that might be experienced under specific operating characteristics.
