Abstract
We present the results of the application of model predictive control (MPC) to
a micro-simulation model with a scenario where shock waves are present, and a
micro-simulation model functions as a substitute for the real-world traffic
system. Shock waves emerge in most cases from traffic jams at bottlenecks,
propagate upstream on the freeway, and can remain existent for a long time and
distance. This increases travel time, is potentially unsafe, and increases
noise and air pollution.
Previously reported results using MPC to eliminate shock waves, showed an
improvement of 20% of the total time that the vehicles spent in the network.
However, they were based on the assumption that the simulation model
(representing the real world) and the prediction model are the same, which may
have lead to overoptimistic results.
In this paper a micro-simulation model (Paramics 5.1 by Quadstone) is used to
represent the real world, which results in a model mismatch between the
simulation model and the prediction model. We show by simulation that even in
the case of a model mismatch the controller is able to suppress or remove shock
waves.
