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.
