Iterative procedure for equilibrium network traffic signal setting
Abstract The Equilibrium Network Traffic Signal Setting problem is an open research area. It can be approached using global optimization models or iterative procedures. In this paper, after a brief review of the state of the art, the main characteristics of the iterative procedure ENETS are described. In this procedure, traffic signal setting is performed in two successive steps: green timing and scheduling at each junction, and signal coordination on the network. Green timing and scheduling at a single junction is based on a mixed-binary linear program with capacity factor maximization. Signal coordination for the whole network is performed by solving a discrete programming model with total delay minimization. The flow assignment stage refers to the separable user equilibrium model with fixed demand, and uses a feasible direction algorithm, which can also be adopted to cover the cases of elastic demand and/or asymmetric equilibrium. An experimental test of ENETS on a small network and a graphical explanation of the procedure are described and discussed.
