Abstract

Dynamic traffic control schemes considering chaotic queue and route choice behavior of drivers are desired for controlling oversaturated road networks. In this research, we formulate a dynamic social optimization problem for oversaturate network in time delay systems, and interrupt the necessary condition. Then we focus on closed-loop structures in road networks and show the constrained conditions to avoid gridlock phenomena. Considering these conditions, we propose a traffic control scheme called Z-control, which minimizes total travel time based on a model predictive scheme. In numerical studies, we consider 2 scenarios for drivers' route choice behavior and show the effectiveness and remained problems of our proposed Z-control.
