Abstract
The main goal of this paper is the proposal and simulation of a SPEed limit
controller for Recurrent Traffic jams (SPERT) that approximates the behavior of
an optimal controller when congestion profiles are similar to the typical one.
In order to achieve this goal, the optimal solution for the typical demand
profile is computed and used as a first estimation for the logic-based
controller. If the real congestion differs from the typical one, the values of
the speed limits are adapted by advancing or delaying their activation and
deactivation. Eleven scenarios have been considered in order to test to
proposed controller under different traffic conditions. The results show that
the proposed controller is able to approach the optimal behavior (with a better
performance that previously proposed easy-to-implement VSL control algorithms)
while eliminating on-line computational cost, and increasing robustness.
