Abstract

The problem of designing real-time traffic signal control strategies for large-scale congested urban road networks is considered. A generic, simple, network-wide problem formulation is presented in the format of a discrete-time optimal control problem whose numerical solution is achieved by use of quadratic-programming algorithms. Some procedures enabling the application of the proposed approach in real- time are outlined. Finally, a simulation-based investigation of the signal control problem for a realistic example is aimed at demonstrating the feasibility and real-time efficiency of the proposed approach when compared with a linear multivariable feedback regulator and a nonlinear optimal control approach that is based on a fairly accurate traffic flow model.
