Abstract:
In this paper we deal with model predictive control for ramp metering
on motorways. A discussion of the way ramp metering tries to prevent,
or postpone, congestion on a motorway is presented. As an example, a
real-life motorway in Belgium is presented. We discuss a traffic flow
model that is used in a receding horizon framework and we argue that
the quality of the fit of the traffic flow model to the measurement
data has an impact on the quality of the optimised metering signals.
Therefore, we suggest to re-fit the most sensitive parameters of the
traffic flow model on a regular basis. We conclude this paper with
some simulation results.
