Computationally efficient model predictive control of freeway networks
An efficient model predictive controller utilizing ramp metering/VSL is presented. The underlying modified LN-CTM models weaving effects and capacity drop. Assumptions/restrictions are introduced to solve the original non-convex problem efficiently. Methodology involves solving a sequence of linear programs. Characteristics of the solution and the role of variable speed limits are investigated.
