Abstract
At freeway bottlenecks shock waves may appear. These shock waves result in
longer travel times and in sudden, large variations in the speeds of the
vehicles, which could lead to unsafe and dangerous situations. Dynamic speed
limits can be used to eliminate or at least to reduce the effects of shock
waves. However, in order to prevent the occurrence of new shock waves and/or
negative impacts on the traffic flows in other locations, coordination of the
variable speed limits is necessary. In this paper we further extend our results
in connection with a model predictive control (MPC) approach to optimally
coordinate variable speed limits for freeway traffic. First of all, we include
a safety constraint that prevents drivers from encountering speed limit drops
larger than, e.g., 10 km/h. Furthermore, to get a better correspondence between
the computed and the applied control signals, we now consider discrete-valued
speed limits.
