| Abstract(E) | This study proposes a novel Virtual Traffic Light (VTL) algorithm designed to improve intersection efficiency by adjusting vehicle approach speeds to enable non-stop passage, unlike conventional VTL that rely on stop instructions. The proposed system utilizes vehicle position and speed data to pre-calculate passing order and command deceleration to avoid collisions, accommodating complex scenarios such as right turns against oncoming traffic. Traffic simulations were conducted using SUMO on both a virtual four-way intersection and a real-world road network model in Saitama, Japan, under various traffic demands. Results indicated that in low-to-medium traffic demand, the proposed VTL reduced travel time compared to physical traffic lights and outperformed conventional VTL. However, in high-demand scenarios, the algorithm caused severe congestion and deadlocks, increasing travel time by over 300% due to extremely low command speeds. The findings demonstrate that while the proposed non-stop control enhances efficiency in lower traffic, conventional cycle-based control remains more robust in high-density environments. |
