Abstract:
We develop a day-to-day route choice control method that is based on model predictive control (MPC). For the route choice we assume that drivers base their decision on the experienced travel times. These travel times can be influenced via existing control measures, e.g. outflow limits or variable speed limits. This allows us to indirectly influence the route choice of the drivers. In previous work we have developed a route choice control method for networks with simple, non-overlapping routes, single destinations, and constant or piecewise constant flows. In this paper we extend this method to networks with overlapping routes and with restricted link inflow capacities. We illustrate the control approach with a case study for a simple network with four routes.
