Traffic signal optimization is the process of adjusting traffic signals to improve the flow of vehicles and pedestrians at intersections. This involves analyzing traffic patterns, vehicle counts, and pedestrian movements to determine the best timing for each signal. The goal is to reduce wait times, minimize congestion, and enhance safety for all road users. By using advanced technologies like traffic cameras and sensors, cities can gather real-time data to make informed decisions about signal timing. This can lead to more efficient traffic management, reduced emissions, and a better overall experience for commuters.
