AT-GRADE CROSSINGS OF LIGHT RAIL TRANSIT. ABRIDGMENT

The purpose of this paper is to provide a methodology for analyzing and estimating the effect of semiexclusive LRT line on motor-vehicle traffic. Four major concerns are identified: The expected level of impact on traffic; the improvements required in terms of added lanes; And, the minimum grade separation requirements. This type of analysis may provide the transportation planner with the tool by which the grade separation requirement could be minimized, or staged to some future year for the cases in which the motor vehicle flow was estimated at the time of the analysis would exceed the capacity, the additional ROW for crossing improvement was unavailable or too costly, or totally grade-separated intersections must be considered. The results of this analysis indicate that the deployment of LRT semiexclusive lines in fringe areas is a feasible alternative to transit lines that are totally grade-separated, fixed guideways. This analysis also indicates that, for LRT systems planned for multicar operations at high service frequencies, locating transit stops at grade crossing is desirable to reduce traffic impact.
