Simulation effort shows that connected vehicle-enabled proactive signal control systems can reduce fuel consumption by 18 percent with full market penetration.

University research evaluates connected vehicles at intersections.

January 2018

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.


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.


With proactive signal timing control, fuel consumption decreased by 18 percent.
