Anticipative model predictive control for ramp metering in freeway networks

Abstract

When implementing ramp metering in the context of freeway networks, traffic can spontaneously re-route due to the applied control actions. Although this re-routing can have an important impact on the resulting traffic situation in the traffic network and on the performance of the traffic network as a whole, re-routing is not automatically included in current model predictive frameworks for freeway traffic control. Therefore, we propose a method to calculate and incorporate the re-routing effects into the model predictive framework. In this way, we realize anticipative model predictive control for ramp metering in freeway networks.
