This paper carries on the recent work of Yang and Wang (2011) on tradable credit schemes by considering heterogeneous users with different value of time (VOT). Given a tradable credit scheme, the user equilibrium (UE) and market equilibrium (ME) conditions with heterogeneous users are formulated into a variational inequalities (VI) problem. Sufficient conditions for uniqueness of the aggregate UE link flows and then the ME credit price are established. Appropriate tradable credit schemes are developed to decentralize system optimal and Pareto-improving network flow patterns. Extension is made to the elastic demand case.
Highlight► Tradable credit schemes are investigated in networks with heterogeneous users. ► A variational inequality problem is formulated to obtain equilibrium solutions. ► Sufficient conditions for unique equilibrium link flow and credit price are offered. ► Credit schemes for system optimal and Pareto-improving flow patterns are provided.
