Adaptive system optimises traffic flow

**************************************

The Transport Department trialled the Real-time Adaptive Traffic Signal System, which computes and optimises traffic signal timing by utilising artificial intelligence to analyse pedestrian and vehicular flows. On the back of the successful trial, the department plans to extend the system to about 50 independent signalised junctions in phases from 2026.

News.gov.hk spoke to a Transport Department engineer to learn more about the system and the department's future plans for it.

The story is available at www.news.gov.hk/eng/feature from today (November 23) in text and video format.
