Looks like the traffic woes of Hyderabad citizens will reduce in the days to come. For better traffic management at junctions in the state capital, the Greater Hyderabad Municipal Corporation (GHMC) has adopted new Adaptive Traffic Signal Control (ATSC) systems that change traffic signal colors based on real-time traffic data.
Developed by the Centre for Development of Advanced Computing (C-DAC), the state-of-the-art adaptive control algorithm known as Composite Signal Control Strategy (CoSiCoSt) adjusts the cycle time, green splits, and offsets to support coordinating with nearby intersections to manage area-wise traffic in real time.
The ATSC systems will automatically and continuously adjust the green times based on the changing approaching patterns of vehicles at an intersection. The idea is to optimize a combination of delay and number of stops.
The system will use camera-based detectors to constantly monitor movements at junctions, and it will create new timing sequences to match them. A centralized system will monitor the data of each junction and optimizes the system at a network level to ensure the synchronization of signals to reduce system delays.
As of now, the ATSC and Pelican Signal System (PSS) projects consist of 122 ATSC signals, 94 pelican signals, and 213 existing HTRIMS signals across Hyderabad. The ATSC system will improve traffic flows along major corridors in the city through a combination of local and network-level optimization.
The 94 Pelican signals equipped with a push button facility provide safe pedestrian crossing, and these signals have been installed at strategic locations such as hospitals, colleges/ schools, and commercial, public places where the pedestrian footfall is high.
