Reinforcement learning optimizes urban street design and traffic signals

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed DeCoR, a novel reinforcement learning framework designed to optimize urban street design and traffic signal control. The system first learns to generate optimal crosswalk layouts by encoding pedestrian networks as graphs. Subsequently, it develops adaptive signal timings to minimize delays for both pedestrians and vehicles. In simulations on a real-world urban corridor, DeCoR significantly reduced pedestrian wait times and improved traffic flow, demonstrating robustness to varying demand and layout changes. AI

    DeCoR: Design and Control Co-Optimization for Urban Streets Using Reinforcement Learning

    Modern vision systems can detect, track, and forecast urban actors at scale, yet translating perception outputs to urban design remains limited. We introduce DeCoR, a two-stage reinforcement learning framework that leverages flow observations to co-optimize crosswalk layout and n…
