“…Congestion can be dissipated by raising the outflow [17], by limiting the inflow to a traffic jam or shock wave [18,19] or by homogenising the general traffic flow [20,21]. All studies are based on the use of variable speed limit signs and static speed assistance [22,23].…”

“…The first emphasizes the homogenization effect [1], [2], [5], [16], [15], whereas the second is more focused on the prevention of traffic breakdown [9], [10], [4]. The idea of homogenization is that speed limits reduce the speed differences between vehicles by which a higher (and safer) flow can be achieved.…”

Abstract-We present a model predictive control (MPC) approach to optimally coordinate variable speed limits for highway traffic. The basic idea is that dynamic speed limits can create traffic conditions where shock waves can damp out faster. The control objective is to minimize the total time that vehicles spend in the network. For the prediction of the evolution of the traffic flows in the network we use an adapted version of the METANET model that takes the variable speed limits into account. 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 results in an adaptive, on-line control strategy that automatically takes changes in the system parameters into account.
