Connected Vehicle-Enabled Proactive Signal Control for Congestion Mitigation on Arterial Corridors

Summary Information

This research developed a proactive signal control system based on connected vehicles to minimize vehicle delay at multiple intersections. The system utilized connected vehicles to accurately predict the volumes entering the intersection through different movements.

METHODOLOGY

Macroscopic simulations of isolated and multiple intersections were used to estimate the effectiveness of the system at reducing vehicle delay. Signal timing was optimized based on a short-term prediction of total vehicle delay at a sample intersection.

In addition, the study used a microscopic traffic simulator (INTEGRATION) to emulate the performance of three consecutive intersections on FM 528 near Houston and the potential impact of implementing connected vehicle enabled proactive signal control. The analysis compared the performance of the proactive signal control system against a well-tuned fully actuated signal control design.

FINDINGS

Compared to well-tuned fully actuated control, proactive signal control systems supported by connected vehicle data can reduce fuel consumption by 18 percent.
