Modelling and real-time control of traffic flow on the southern part of Boulevard Peripherique in Paris: Part II: Coordinated on-ramp metering

A coordinated, feedback ramp metering strategy is derived for the southern part of Boulevard Périphérique in Paris. The derivation is based on well-known methods of Automatic Control theory (Linear Quadratic Optimisation) using a linearized version of a nonlinear macroscopic traffic flow model presented in a preceding paper. Efficiency of the presented strategy is tested and compared to no control, fixed-time control, and local feedback control on the basis of simulation investigations. [See previous abstract.]
