Bangkok Metropolitan Administration (BMA) has started upgrading traffic signals at various intersections, incorporating an adaptive system using CCTV and AI technology to adjust in real time. This initiative, detailed in a February 20 Facebook post, aims to transition from fixed-timing to automated adaptive control, improving convenience and reducing time on the roads.

The BMA manages 746 intersections, with 578 having traffic lights. Currently, 433 of these use fixed signals, 71 have adaptive loop detectors, and 74 have been updated to the new adaptive real-time CCTV system. Fixed-time signals often cause inefficiencies, like green lights with no traffic or unnecessary red light waits.
The new adaptive system uses cameras and intelligent processing to react to real-time traffic. By adjusting signal timing based on actual traffic, the system aims to improve traffic flow, reduce gridlock, and minimize wait times.
In 2024 and 2025, the BMA upgraded 74 intersections on major roads like Sukhumvit and Rama IX. Evaluations show this improved traffic flow by 10% to 41%. Plans are set to expand this system to an additional 50 intersections this year, reported The Thaiger.
