OPTIMAL COORDINATION OF RAMP METERING AND VARIABLE SPEED CONTROL : AN MPC APPROACH

In this paper, the authors present a model predictive control (MPC) approach for optimally coordinating variable speed limits and ramp metering for highway traffic. Working with the premise that speed limits can increase the range in which ramp metering is useful, the objective is to minimize the total amount of time that vehicles spend in the network. An adapted version of the METANET model, which takes into account the variable speed limits, is used to predict the evolution of the traffic flows in the network. The coordinated control results in a network with less congestion, a higher outflow, and a lower total time spent. In addition, the receding horizon approach of MPC leads to an adaptive, online control strategy that automatically takes into account changes in the system parameters.
