Abstract
We now apply the model predictive control (MPC) of speed limits that we have
presented in previous publications - viz., "Shock wave elimination/reduction
by optimal coordination of variable speed limits," (by P. Breton, A. Hegyi, B.
De Schutter, and H. Hellendoorn,
Proceedings of the IEEE 5th
International Conference on Intelligent Transportation Systems
(ITSC'02), Singapore, pp. 225-230, Sept. 2002); and "MPC-based optimal
coordination of variable speed limits to suppress shock waves in freeway
traffic," (by A. Hegyi, B. De Schutter, and J. Hellendoorn,
Proceedings of the 2003 American Control Conference, Denver,
Colorado, pp. 4083-4088, June 2003) - to a calibrated METANET model of a 19 km
stretch of the real-world freeway A1 in The Netherlands. This freeway regularly
suffers from shock waves originating mainly from on-ramps, and speed limits are
now used to suppress these shock waves. First, we calibrate and validate the
extended METANET model with data from the A1 freeway, and we use the Delft OD
method to estimate the origin-destination patterns that are needed for the
simulation of the destination oriented traffic. Next, we verify from data
whether the necessary conditions for applying speed limits against shock waves
are satisfied. We show that the MPC controller performs well even under the
assumption that the traffic demand is not known on the on-ramps and is known
for only a few kilometers upstream and downstream of the controlled stretch.
This approach results in an improvement of the total time spent in the network
with about 15%.
