SUE Model Based on a Reliability-Admissible Reasonable Route Set

This paper proposes a reliability-admissible filtering mechanism to generate the reasonable route set for the traditional SUE model. This mechanism still takes into account traveler´s cost-susceptivity, which is able to dispel the impact of dimension on the traffic assignment. The filtering formula is presented and further estimated based on the Gumbel distribution assumption for the route disutility. The corresponding Logit-based SUE model and MSA-based algorithms for the multi-class case are presented, and are verified via numerical examples. Numerical results illustrate that the hazardous routing behavior will cause heavy traffic crowding and reduce the utilization efficiency of network. In addition, a reasonable structure of travel demand will contribute to alleviate the urban traffic congestion.
