Robust Synchronization of Actuated Signals on Arterials

Abstract

A robust approach is presented to synchronize actuated signals on arterials, mainly to address the issue of uncertain (not fixed) starts and ends of green of the sync phases. The robust counterpart of the mixed-integer linear programming model (MILP) for bandwidth maximization is developed to minimize the expected regret with respect to a set of high-consequence scenarios. The robust counterpart, another MILP, can be solved in polynomial time. Macroscopic and microscopic simulations are conducted to corroborate the validity and robustness of the resulting coordination plans.
