Samenvatting
The importance of highway rail grade crossing safety, Intelligent Transport System (ITS), preemption of traffic signals and constant warning time for grade crossing control are reviewed. The requirement for a grade crossing simulation tool was realized and the Traffic Simulation Integrated System-Corridor Microsopic Simulation (TSIS-CORSIM) was extended to the Highway Railroad Grade Crossing (HRGC). This simulation was then applied to safety-related studies, traffic signal preemption requirements, and the identification and collection of measures of effectiveness for different grade crossing safety enhancement options.
