Diffusion model plans traffic for signal-free intersections

Researchers have developed DSIP, a novel multi-agent motion planning framework that utilizes a generative diffusion process for managing traffic at signal-free intersections. This approach shifts from traditional timed traffic signals to continuous trajectory optimization for multiple vehicles. Evaluations using the SUMO platform indicate that DSIP significantly reduces average delay and increases average speed, particularly in medium to high traffic densities, outperforming both fixed-time signals and existing reinforcement learning controllers. AI

IMPACT This research suggests diffusion models can enhance urban traffic flow efficiency by optimizing vehicle trajectories at intersections.

    DSIP: A Dynamic Coordination Planner for Signal-Free Intersections using Diffusion-Model-Based Multi-Agent Motion Planning

    arXiv:2606.30694v1 Announce Type: cross Abstract: Traffic signal control at urban intersections inherently introduces stop-and-go behavior, resulting in increased delays and reduced traffic efficiency, especially under high traffic demand. With the emergence of connected and auto…
