    Pareto efficient strategies for regulating public transit operations

    This paper investigates how the local authorities could efficiently regulate the public transit, which is operated by a private firm. Both the waiting time at stops and the in-vehicle congestion costs are take...

    Equilibria and Inefficiency in Traffic Networks with Stochastic Capacity and Information Provision

    In this paper, we study the inefficiencies of various behavior equilibria in traffic networks with stochastic capacity and information provision. Variational inequality models are presented to formulate the tr...

    A Stochastic Model for Combined Activity/Destination/Route Choice Problems

    In travel behavior modeling, an important topic is to investigate what drives people to travel. A systematic analysis should examine why, where and when various activities are engaged in, and how activity enga...

    A Combined Algorithm for Solving and Calibrating the Stochastic Traffic Assignment Model

    This paper studies Fisk's stochastic user equilibrium (SUE) assignment model in which travellers are assumed not to have perfect knowledge of the traffic system. It is shown that the stochastic properties of t...
