DYNAMIC ROUTING DECISIONS FOR COMMERCIAL VEHICLE OPERATIONS BASED ON REAL-TIME TRAFFIC CONDITIONS

The application of the ITS (Intelligent Transportation Systems) technologies to facilitate freight mobility requires dynamic routing decisions to reduce operational costs and enhance service levels. While most route planning or scheduling methods studied in the literature assume fixed or static travel times of the networks, this paper attempts to focus on the dynamic routing decisions in response to the real-time information. A microscopic traffic simulation model coupled with a link-to-link shortest path searching with turning penalties is suggested and developed to evaluate the potential benefits of the dynamic routing decisions, which considers both updated link travel times and detected incident conditions. The simulation results are described and discussed in this paper. Some interesting issues for future research needs are recommended. This research will help logistics companies to assess the benefits of the routing advisory systems for their day-to-day operations
