AI traffic lights to improve Subang Jaya roundabout flow

SUBANG JAYA residents can look forward to relief from daily traffic gridlock at Bulatan Kewajipan once traffic upgrades are completed in the first quarter of 2027.

Subang Jaya mayor Datuk Amirul Azizan Abd Rahim said three artificial intelligence- (AI)powered traffic lights would be installed to control traffic flow at the roundabout.

The plan will also involve the reorganisation of traffic from SS15 towards Bandar Sunway through a U-turn after the Sri Kuala Lumpur School, he said when chairing the Subang Jaya City Council (MBSJ) full board meeting at its headquarters in USJ5, Subang Jaya, yesterday.

“Motorists will also see improvements at various road intersections,” he said, adding that the cost for upgrade works would be borne by Sunway Property.

The project, scheduled to start in July and expected to take six months to be completed, is reported to cost over RM100mil.

Last month, StarMetro reported that the roundabout, located at the intersection of Persiaran Kewajipan and New Pantai Expressway (NPE), served as a key gateway for motorists travelling in and out of Subang Jaya and Bandar Sunway.

The three sets of smart traffic lights are expected to help control traffic flow from SS12, SS13, SS14 and SS15.

Separately, during a site visit to the roundabout with the media, Subang Jaya assemblyman Michelle Ng proposed that closed-circuit TV (CCTV) cameras powered by AI be included as an additional security measure in the upgrade of Bulatan Kewajipan.

She said her office submitted the request to both MBSJ and Sunway Property as the approving authority and developer of the project, respectively.

This, she said, was to address the issue of motorists parking and waiting at the roundabout to pick up students of the international school.

Ng said the line of waiting vehicles stretched from the school entrance until the SS15 post office.

This, she said, contributed to the narrowing of roads and traffic congestion during school pick-up hours.

“The police consistently station personnel during school pick-up hours to monitor and take action against offenders.

“However, they are hampered by situations such as staff constraints,” she told reporters.

Also present were MBSJ councillor Chia Yew Ken and representatives from MBSJ, NPE, Sunway Property and the police.

“The site visit is to determine the number of CCTV cameras required and the matter of jurisdiction,” said Ng.

“Although Persiaran Kewajipan is under MBSJ’s jurisdiction, certain stretches of the roundabout come under NPE’s purview.

“My suggestion is for the CCTV network to be linked to MBSJ’s command centre so that footage can be transmitted directly from MBSJ to the police.

“The CCTV should include AI systems to detect vehicles that are waiting for a longer than normal duration at the roundabout,” she added.

Ng said several trees would be felled to make way for the project’s physical structures.

“We understand the importance of trees in providing oxygen, filtering carbon, reducing the urban heat island effect and enhancing local landscapes.

“As such, MBSJ has imposed a condition on the developer that for every tree felled, 10 new trees must be planted as replacements,” she highlighted.
