Modelling the effects of multi-modal travler information systems

Abstract

This paper proposes a multi-class probit-based stochastic user equilibrium model for assessing the effects of multi-modal traveler information systems (MTIS) on a multi-modal transport network. It can be formulated as a fixed-point problem and solved by a simulation-based heuristic solution algorithm. It is assumed in this paper that the travelers equipped and unequipped with MTIS would make their travel choices following a probit-based stochastic manner when considering alternative paths or modes according to their perceived utilities. The proposed model and solution algorithm can be used to evaluate explicitly the impacts of MTIS services. Numerical results show that the introduction of MTIS would improve the network performance and promote the utilization of public transit under certain market penetration and congestion levels.
