Bangkok reveals smart traffic signals reduce congestion by up to 41%

13 June 2025

Bangkok celebrates the success of its "smart traffic signals." With 72 intersections already equipped, plans are underway to expand to 200 more by next year.

At the Bangkok City Hall (Sao Chingcha), Governor of Bangkok, Chadchart Sittipunt, chaired the 6th meeting of Bangkok’s executive officials, where one of the key highlights was the successful implementation of the adaptive traffic signal system.

The meeting revealed that the city had completed the installation and activation of intelligent traffic signal systems (Adaptive Signal Control) across 72 key intersections since March 2025. These improvements focus on major road junctions in the central areas, which have long experienced significant traffic congestion.
