Coordinated Look-ahead Scheduling for Real-time Traffic Signal Control

Abstract

We take an agent-based approach to real-time traffic signal control based on coordinated look-ahead scheduling. At each decision point, each agent constructs a schedule that optimizes movement of the currently approaching traffic through its intersection. For strengthening its local view, each agent queries the scheduled outflows from its direct upstream neighbors to obtain an optimistic observation, which is capable of incorporating non-local impacts from indirect neighbors. We summarize results on a road network of tightly-coupled intersections that demonstrate the ability of our approach.
