Coordinated Control of Distributed Traffic Signal Based on Multiagent Cooperative Game

Throughput Optimal Distributed Traffic Signal Control

We propose a distributed algorithm for controlling traffic signals, allowing constraints such as periodic switching sequences of phases and minimum and maximum green time to be incorporated. Our algorithm is adapted from backpressure routing, which has been mainly applied to communication and power networks. We formally prove that our algorithm ensures global optimality as it leads to maximum n...

CoSign: A Fictitious Play Algorithm for Coordinated Traffic Signal Control

The problem of finding efficient coordinated signal timing plans for a large number of traffic signals is a challenging problem because of the exponential growth in the number of joint timing plans that need to be explored as the network size grows. In this paper, we employ the game-theoretic paradigm of fictitious play to iteratively converge to a locally optimal coordinated signal timing plan...

Coordinated look-ahead scheduling for real-time traffic signal control

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 observ...

A Game-Theoretic Approach to Distributed Control of Traffic Signals

Game-theoretic techniques have been proved useful in modelling the conflict of interest and the cooperation among agents. This work aims at applying such an approach to model interactions in the domain of decen~alized traffic signal control where either cooperative or noncooperative interactions arise. Case-studies are described in which agents have been assigned either to intersections or to l...
