Abstract
When there are different routes from origin to destination in a network, the
traffic divides itself over these routes. The resulting assignment is often
determined by the travel times on the different routes. When control measures
are implemented the travel times for some routes change, which can lead to a
change in the assignment. This change in assignment can effect the performance
of the whole network, but is often not automatically included in the traffic
control frameworks. In this paper we develop a control method that takes these
re-routing effects into account. A model-based predictive control approach is
used to determine optimal settings for traffic control measures. This control
method stays optimal even when the route choice of the drivers changes. The
method predicts the evolution of the traffic flows and the resulting traffic
assignment, and uses this prediction to obtain the optimal control settings. To
predict the traffic assignment a model is developed that, due to a low
computational complexity, can be used in the controller. As an example we apply
the control method on ramp metering control for a freeway network. With a case
study on a small network we show the effects of the method for ramp metering,
and compare it with ALINEA, an existing ramp metering control method.
