The performance of arterial corridors is significantly determined by the signal control systems at intersections. Currently, most research effort has been spent to investigate adaptive signal control systems with advanced technologies, such as connected vehicles. However, these systems cannot be easily realized due to the limitation of the technologies. This paper aims to develop an innovative platoon-based signal control using the existing platform of actuated signal controller to improve the performance of intersections. The system utilizes existing road facilities, such as loop detectors and cameras, to monitor the arrivals of vehicle platoons from different approaches of intersections, and to search for the optimal signal phasing and timing plan. The specialty of this system is that it applies the conventional signal control equipment making the application in real world less expensive and sustainable. A VISSIM simulation is applied to realize the application and evaluate its effectiveness on reducing traffic congestion at intersection. The system is further applied at one intersection in Houston, Texas to illustrate its real-world benefits. The field experiment indicates that the system reduces vehicle delay about 11% and the average queue length up to 60%.
