Real-time traffic control strategies at the network level have been attracting significant research attention, in particular the perimeter control. This paper continues this research direction, but introduces the heterogeneity of drivers into the modelling framework and proposes a novel control strategy with congestion pricing. The heterogeneity is represented by the difference across drivers in their value-of-time (VOT). The proposed pricing scheme prioritizes vehicles (drivers) with high VOT such that they enter the protected network with less delay through dedicated express toll lanes at the perimeter intersections where a fee is charged. These toll lanes receive more favorable signal times than the normal lanes to ensure a fast service. The proposed approach is tested in a simulated network which resembles the main features of the central area of the city of Zurich, Switzerland. By using the proposed strategy, the traffic accumulation inside the network is still stabilized, and the monetary cost due to delay is significantly reduced at the perimeter. The distribution of the combined cost (including cost due to delay and tolls) is more evenly distributed among VOT groups.
