Bangkok Uses Google AI to Tackle Gridlock and Clean the Air

Thailand AI News: City-wide AI experiment aims to transform Bangkok’s notorious traffic chaos In a groundbreaking move to revolutionize urban mobility, the Bangkok Metropolitan Administration (BMA) has teamed up with Google to launch a cutting-edge artificial intelligence traffic management project designed to tame the city’s chronic congestion. This collaboration, part of Google’s global “Project Green Light” initiative, uses AI-powered insights and real-time Google Maps data to optimize traffic light timings at critical intersections—improving vehicle flow and significantly reducing roadside air pollution.

Launched as a pilot in February 2025, the project has already been rolled out across multiple key intersections in Bangkok. According to Google Thailand’s Country Marketing Manager, Saranee Boonritthongchai, early data from both local and international deployments of Project Green Light indicate major benefits: up to 30 percent fewer stops at traffic lights and roughly 10 percent reductions in emissions from idling vehicles. This Thailand AI News report reveals that more than 55 million car journeys globally are now being guided by the AI-driven traffic signal system each month.

A Smarter System for a Smarter City

Traditionally, most traffic lights in Bangkok have operated on fixed timing schedules—ignoring real-time congestion and driver behavior. But with Project Green Light, that outdated method is being phased out. The system harnesses AI to analyze daily traffic volumes, patterns, and delays, then offers tailored recommendations on when to extend or shorten green and red light durations based on actual conditions. Traffic engineers from the BMA review each AI-generated suggestion for safety, feasibility, and impact before applying changes.

Bangkok Governor Chadchart Sittipunt has emphasized that AI will now be a core part of the city’s urban planning toolkit. “We are seriously implementing AI to tackle long-standing traffic issues,” he said, noting that an AI steering committee has been formed to ensure technology is effectively used across multiple departments.

Bangkok Among Global Leaders in AI Traffic Innovation

With only 18 cities worldwide chosen to participate in Project Green Light, Bangkok’s inclusion is a significant milestone. BMA Deputy Governor Wisanu Subsompon expressed pride in the city’s involvement, saying, “By applying AI and map data to understand the travel behavior of our citizens, we can better manage congestion and improve commuter experience.”

Over the past three months, AI systems have been continuously monitoring traffic at hundreds of junctions, feeding data into algorithms that determine how to fine-tune light cycles for optimal flow. Once a change is implemented, the system measures its impact and delivers insights to BMA engineers for further optimization.

Google’s Saranee Boonritthongchai added, “We’re thrilled with the initial results and look forward to scaling the program to more intersections across Bangkok.”

The Promise of AI for Bangkok’s Urban Future

With Bangkok’s population surging and vehicle usage showing no signs of slowing, smart traffic solutions are no longer a luxury but a necessity. The integration of Google’s AI-powered traffic technology marks a pivotal shift toward a more intelligent, adaptive, and environmentally conscious city.

This initiative has the potential not only to improve daily life for millions of commuters but also to set an example for how Southeast Asian megacities can embrace digital innovation to solve long-standing infrastructure challenges. As this project expands and evolves, Bangkok could become a leading global model in AI-powered urban mobility.
