In the recent past, numerous Variable Speed Limit (VSL) approaches have been designed to resolve traffic jams on the freeway. In this work, the theory of one such VSL strategy -- COoperative Speed Control ALgorithm (COSCAL v2) -- is analytically extended for integration with Ramp Metering (RM), based on traffic flow theory. COSCAL v2 is a reactive feedback VSL strategy that resolves jam waves using...
This paper proposes an efficient model predictive control strategy that is based on the parameterization of a variable speed limit control scheme. Due to the paramiterization, the solution spaces reduces which leads to improved computation time. The parameterized control scheme consist of a speed-limited area in which a constant speed limit is imposed. By changing the position of the head and tail...
