Abstract

We propose an alternative approach to route planning where optimality of the routes is primarily defined based on their impact on overall utilization of the transportation network rather than best interests of individual travelers. With this approach, the optimization criteria directly capture the transportation network/system interests, and therefore, route planning becomes a system optimization problem with which we seek a set of routes for the current travelers such that the overall utilization of the transportation network/system in terms of one or more utility functions (e.g., throughput-of/mobility-through of the transportation network, quality of transportation through the transportation network, etc.) is optimal. With such an approach, while we primarily optimize routes for network utilization, when possible and as a secondary objective we can still seek routes that are near-optimal (if not optimal) for individual travelers. Accordingly, with this proposal we will introduce a multi-criteria route planning solution with one or more network utilization criteria as primary optimization objective(s), and one or more measure(s) of best traveler interests as secondary objective(s).
