Abstract:
We present a model predictive control (MPC) approach to optimally
coordinate variable speed limits for freeway traffic. In particular,
we consider discrete-valued variable speed limits. Moreover, we also
impose a safety constraint that prevents drivers from encountering
speed limit drops larger than, say, 10 km/h. The control objective is
to minimize the total time that vehicles spend in the network. This
approach results in dynamic speed limits that reduce or even eliminate
shock waves.
