If you’re tired of being stuck in bumper-to-bumper traffic on your way to work or weekend brunch, there’s good news. Bangkok has officially completed a major transport upgrade. At the sixth executive meeting of City Hall, Governor Chadchart Sittipunt revealed results from the city's latest development of the adaptive traffic signal system which is slashing intersection delays by 10-41 percent.
The project was launched in 2024 and fully rolled out by March 2025, covering 72 intersections across the city’s busiest roads. The intersections selected for this system are located in areas known for heavy traffic, including: Rama IX Road, Din Daeng Road, Phaya Thai Road, Sukhumvit Road, Ploenchit Road, Rama I Road, Rama IV Road, Sathorn Road, Silom Road, Surawong Road, Si Phraya Road and Phahonyothin Road.
These are the roads that, until recently, tested your patience and probably your playlist. So, what’s changed?

The traditional fixed-timer system has been replaced with a flexible, intelligent setup. The new technology uses image-processing cameras to detect real-time traffic volume and a central processing unit that uses the AI to optimise traffic light timing and reduce delays. This allows for:
- Counting traffic flow in every direction
- Switching signals when no cars are detected
- Measuring intersection delay to prevent congestion buildup
This means smoother flow, faster commutes, and hopefully fewer honks and headaches. The perfect lifestyle upgrade for everyone who moves through Bangkok and a win for drivers.
So whether you're heading to a rooftop bar in Silom or rushing to a meeting in Asoke, this traffic revolution might just get you there quicker and a little less sweaty.
