A SIMULATION BASED EVALUATION OF DYNAMIC ROUTE GUIDANCE FOR TRAFFIC MANAGEMENT AT HIGHWAY RAIL INTERSECTIONS

Highway-rail intersections are unique in the sense that trains always have right of way at these intersections. The increase in travel demand in urban areas with active railway lines makes these grade crossing intersections potential traffic hot spots, where bottlenecks can very easily arise, disrupting traffic operations and spilling back to impede smooth traffic flow in surrounding areas as well. This paper suggests the deployment of a dynamic and preferably real-time route guidance infrastructure, using traveler information systems such as Variable Message Signs (VMS). The proposed system is used to advise travelers of alternate routes to their destinations in the event that their original routes entail excessive delays due to the passage of trains and subsequent closure of grade crossings. Microscopic simulation using CORSIM is used to demonstrate the feasibility of this framework by examining its impact on average system-wide origin to destination travel times. Multiple cases are examined, corresponding to various levels of information that could be used to drive the dynamic route guidance system and an ideal level of information is recommended. An additional case considers a scenario where selected intersections are controlled in real-time using RHODES (Real-time Hierarchical, Optimized, Distributed and Effective System), a traffic adaptive signal control system developed at the University of Arizona. The cases considered are one-time deployments only and a study of traffic equilibrium was not included. Simulation results indicate that the availability of complete information about train crossing times in conjunction with adaptive intersection signal control using RHODES yields maximum reduction in average vehicle O-D travel times
