AI optimizes traffic signals, cutting delays and emissions

Researchers have developed a reinforcement learning (RL) system to optimize traffic signal control in urban intersections, particularly for IoT-enabled environments. The system, utilizing Proximal Policy Optimization (PPO), dynamically adjusts green light durations based on local traffic conditions without needing future demand predictions. Simulations in Kuwait demonstrated significant reductions in average vehicle delay (46% compared to fixed-time control) and CO2 emissions (23%), showing promise for smart-city transportation. AI

IMPACT This AI approach could significantly reduce urban traffic congestion, fuel consumption, and emissions in smart cities.
