The Metropolitan Manila Development Authority (MMDA) installed three sensor-based traffic signal lights amid the ongoing replacement of traffic light timers to improve the flow of vehicles in major thoroughfares, particularly on road intersections.

MMDA chairman Don Artes said the installation of three sensor-based traffic signal lights is part of the shift to adaptive signalling system, adding that they all came from the North Luzon Expressway (NLEX) Corporation.

He said the traffic lights were installed on C3 Road, Caloocan, España Boulevard (corner Antipolo St.), and Magsaysay Boulevard in Manila where around 143,000 motor vehicles pass daily.

“The sensor-based traffic signal lights will help organize vehicle flow and manage pedestrian crossings in the said areas. These newly installed signal lights are not just ordinary traffic signals. They follow MMDA’s updated standards and are equipped with adaptive signaling systems that use sensors instead of traditional timers,” said Artes.

“This technology allows real-time adjustment to traffic conditions, which means better vehicular flow and safer pedestrian crossings,” he added.

Earlier, Artes revealed the MMDA plan to use sensor-based traffic lights, citing observations of erring motorists usually speeding off to beat the red light, especially amid heavy traffic flow.

The sensor-based traffic lights, on the other hand, depend on the volume of vehicles monitored by the traffic light system.

The green light would blink five times before it would switch to yellow light for three seconds, and finally to red.

Metro Pacific Tollways Corporation (MPTC) Chief Regulatory Officer Arrey Perez said the new and modern signal lights will serve to improve traffic management, enhance road safety, and support sustainability.

“This initiative of putting traffic signal lights reflects our commitment to easing congestion and improving the mobility experience for all—whether travelling along expressways or local roads. By working together, we are creating safer roads not only for motorists but also for our community,” Perez said.
