Steady-State Traffic Signal Control With Variable Phase Combinations and Sequences

:The space distribution of traffic flows is often unbalanced, resulting in regional congestion, and even oversaturation of the network. In this paper, the steady-state traffic signal control design approach, with consensus-based control objective of network states, is proposed. A traffic flow model is first introduced based on store-and-forward modeling procedures. Furthermore, a link-based distributed signal control law is proposed with the consensus of link occupancies as control objective, and moreover control approach for phase combinations and sequences is introduced, especially in case of higher network demands. At last, simulation investigations for a topological network in Beijing are conducted in VISSIM software, which shows that the proposed approaches can improve performance indices of the network and then reduce local traffic congestion.
