Description:

This research aims to develop a unified theoretical and simulation framework for analyzing and designing signals for stationary arterial networks. Existing traffic flow models used in design and analysis of signal control strategies are either too simple to be realistic or too detailed to be efficient. In this research we apply the link transmission model to formulate, analyze, and simulate traffic dynamics in a signalized arterial network. We first analytically derive approximate macroscopic fundamental diagrams for stationary traffic patterns with different network topologies, road conditions, driving behaviors, and signal settings. We then analyze congestion mitigation effects of different signal settings, including cycle lengths, green splits, and offsets. We further formulate and solve an optimization problem with the network flow-rate as performance measure to find optimal signal control parameters. We derived simple formulas for the optimal signal cycle length and offset under different traffic conditions to improve arterial network performance.
