Chennai Intelligent Transport System (AI-Adaptive Traffic Signals)
Chennai's Intelligent Transport System equips 165 core-city junctions with camera-fed adaptive signal control, plus incident detection at 58 locations, variable message signs at 17 sites and red-light violation cameras at 50 junctions. It is built under a roughly ₹530-crore contract with Larsen & Toubro, signed 31 March 2023 with Japan International Cooperation Agency financing, and grew out of a 17-junction pilot running since January 2024. By March 2026, civil works for junction improvements were complete at only 104 of the 165 junctions, with the Greater Chennai Corporation targeting full operation in August 2026 — meaning most of the network was still under construction, not yet adjusting signals live, as of that date.
