On May 26 at the Bangkok City Hall, Mr. Ekkwaranyu Amrapal, spokesperson for the Bangkok Metropolitan Administration (BMA), announced a partnership with Google on "Project Green Light," aimed at optimizing traffic signal timing at intersections to improve traffic management and reduce PM2.5 emissions from transportation.
Launched in February, the project uses Big Data and Artificial Intelligence (AI) to analyze real-time driving behavior and adjust traffic light timings to better match current traffic conditions. This has helped reduce vehicle stops by up to 30%, alleviating stop-and-go congestion and enhancing overall travel efficiency.
So far, signal timings have been adjusted at over 50 intersections across Bangkok. The initiative is expected to reduce greenhouse gas emissions by approximately 10%. Additionally, BMA is utilizing probe data from GPS-equipped mobile devices to analyze travel origin-destination (O/D) patterns, which supports further traffic optimization measures—such as signal adjustments and traffic lane management at major junctions. Pilot implementations have begun at Ratchathewi Intersection, Rama IX Intersection, and Taksin Bridge.
Mr. Ekkwaranyu emphasized BMA’s commitment to using technology for smoother daily commutes. He encouraged the public to report ongoing traffic issues via the Traffy Fondue platform to enable targeted solutions.
