Adaptive Traffic Signal Control | New Way To Reduce Traffic

1. Introduction Urban areas are increasingly grappling with the problem of traffic congestion, which not only leads to longer travel times but also results in excessive fuel consumption and harmful emissions. With cities growing in both size and population, efficient traffic management has become a priority for city planners. One of the most promising solutions to address this challenge is Adaptive Traffic Signal Control (ATSC). By adjusting traffic light timings based on real-time data, ATSC significantly reduces delays and improves traffic flow, thus offering a smarter way to manage urban mobility. 2. What is Adaptive Traffic Signal Control? Adaptive Traffic Signal Control (ATSC) is an advanced traffic management system designed to optimize traffic light timings in response to real-time traffic conditions. Unlike traditional systems that operate based on fixed schedules, ATSC uses real-time data to dynamically adjust traffic signals. This results in fewer traffic jams, smoother vehic
