Model predictive control for intersections

At intersections that are controlled by vehicle-actuated controllers the movements receive green in a fixed order. The number of waiting vehicles, the time they are waiting, whether a platoon approaches, etc. are not taken into account. The result is a neatly arranged control plan, but also a way of control that is not capable of minimising the total loss for the complete intersection. Model predictive control (MPC) determines its next control action on predictions of the effect of different combinations of control actions in time. In a Dutch presentation for different groups of traffic engineers Ronald van Katwijk provided the participants with a better insight into the possibilities of MPC for the current practice and for the future.
