At noon on November 8, information from the Traffic Police Department (CSGT) - Hanoi City Police said that the unit is coordinating with specialized units to upgrade the traffic light control system in the area, applying modern technology, artificial intelligence (AI) and real-time data, to improve command, control and reduce traffic congestion.
During the implementation period, the rear light system at some intersections will temporarily not work to serve the upgrading and replacement of control equipment.
The Hanoi Traffic Police Department recommends that traffic participants strictly follow traffic light signals and instructions from the traffic police force to ensure safety, order and smooth traffic during construction.
According to the Hanoi Traffic Police Department, currently, the traffic light system at 563 intersections in Hanoi is directly managed and operated by the City Police. This is one of the key infrastructure in traffic organization and operation, ensuring traffic order and safety in the capital.
However, most of this system was invested in many years ago, old technology, only suitable for low traffic conditions.
Meanwhile, Hanoi's transportation is increasingly complex, with private vehicles accounting for a high proportion, the average travel coefficient reaching 2.73-3.1 trips/person/day, and there has been no breakthrough in public transport, leading to increased congestion.
The Hanoi Traffic Police Department has reviewed and evaluated the entire traffic light system and identified the key task of upgrading and modernizing the control system, aiming for flexible control capability, adapting to real-time traffic data.
The key solution deployed is collecting traffic data using specialized cameras, analyzing using artificial intelligence (AI) with an accuracy of up to 95%, connected to a smart traffic light controller.
The system allows automatic adjustment of green light and red light times according to actual flow, helping to reduce waiting time and increase traffic at intersections.
The system has been tested in 2024 at two intersections on the Vo Chi Cong route (Xuan La and Nguyen Hoang Ton) and has shown clear efficiency (waiting time has been reduced by 20-30%, traffic flow is moving smoothly, limiting congestion during rush hour).
The new system is also capable of synchronously controlling many intersections on the same route and corridor, optimizing traffic volume for the entire route.
"When deployed synchronously, the system not only contributes to reducing congestion, improving command and control efficiency but also reduces pressure on the traffic police force in directly regulating at the switch," informed the Hanoi Traffic Police Department.
