Abstract

The role of initial credit distribution scheme ICDS in managing network mobility has long been overlooked in previous studies of tradable credit scheme TCS, which may make their results disputable in the reality, as the travelers possessing leftover credits can get some subsidy from the credit market and offset part of travel cost. In this paper, the disequilibrium phenomenon of previous user equilibrium UE solution is shown when traveler’s cognitive illusion CI is considered. Then, a new UE condition with TCS is defined with the ICDS and CI explicitly considered. To comprehensively reveal the impacts of ICDS on UE solution, four different types of ICDS are introduced and analyzed in a unified variational inequality VI modeling framework. The uniqueness of the UE link flow and market equilibrium ME credit price is also investigated. Furthermore, the mathematical program with equilibrium constraint MPEC for the optimal ICDS design problem is established, with the optimization objective being maximizing network reserve capacity. A modified relaxation algorithm is adopted to solve the MPEC. The numerical example shows that a properly designed ICDS can not only improve the network reserve capacity, but also decrease the travel cost of all the travelers in the network simultaneously.
