New intelligent traffic light system expected to reduce gridlock in KL

A NEW traffic management system called TrafficSens would be implemented early next year to provide a smoother traffic flow in various parts just outside the city centre.

It was developed locally by TrafficSens Systems (M) Sdn Bhd, a company given a government grant of RM1.8mil to research and develop the system.

The TrafficSens system will be up and running after its integration with DBKL’s existing automated traffic management system in 62 locations throughout Kuala Lumpur’s city centre by April next year.

The company’s managing director Datuk Tan Boon Hock said the system has a software that acquires and learn the traffic flow where it is deployed and adjusts the traffic flow accordingly.

It can be likened to having a traffic policeman permanently stationed at each traffic light.

Through the TrafficSens intelligent learning system, the “stationary cop” would also be constantly communicating with other policemen to direct oncoming traffic.


“With the development of smart-traffic management sytem, traffic light timers that are being used presently to control the city’s vehicle flow is a thing of the past.

“The artificial intelligence that we developed for the traffic lights is able to detect the volume of vehicles during peak hours and synchronise with its ‘peers’ to provide smooth flow,” explained Tan.

The TrafficSens system is independent as it has an early warning system that is hooked up to the traffic management centre via 3G mobile network.

“If there is a faulty light in the array of TraffiSens system, it will despatch a warning via SMS to the command centre.

“We can tackle this immediately to prevent disruption in the traffic management system where the TrafficSens is deployed.”

In downtown Toronto, Canada, the system was installed at 59 intersections and the results showed a reduction in the average intersection delay ranging from 27% to 39% and travel-time savings of 15% and 26% along the busiest routes.

A spokesperson from Kuala Lumpur City Hall (DBKL) said they were in the process of finalising the details of the system.

“Currently, the hardware has been installed in stages at certain traffic light junctions, but the system has yet to go online.”

He said TrafficSens would enhance the existing Itaka and Scat traffic light system used in some parts of the city.

One of the reasons why the TrafficSens system was selected by DBKL was the fact that it was locally developed, he added.

“This makes it easier, cheaper and quicker to get support and spare parts.

“Additionally, this system will lessen the load in the traffic control room as it does not need to ‘communicate’ back here.

“We are however still able to control these lights manually which is good news in emergency situations,” the spokesperson said.

Residents of Taman Desa were the first to be able to “test” TrafficSens when it was installed at the Jalan Desa — Jalan Desa Utama cross junction recently.

Edmund Teoh, 27, a personal assistant who has lived in the area all his life said he had noticed smoother journey while passing through.

“The lights are now more often than not green when you need it to be.

“However, DBKL should also look at other means to improve traffic and relief rush hour congestion,” he said.

One such example is the traffic light T-junction of Jalan Desa Utama and Jalan Desa Bakti where cars are parked all along the side of both roads.

“Those turning left from Jalan Desa Bakti onto Jalan Desa Utama especially are at a disadvantage as not only is there a lack of space but the road is on an incline so cars are slower and not many manage to make the turn when the lights are green,” he added.

This problem is worsened during morning rush hour and after school during the day when school buses ply the road.
