Hanoi is increasingly using AI and digital data to manage traffic, detect congestion and monitor violations. The city has 23 green wave routes, where traffic signals are coordinated.
The measures are part of the city's efforts to implement Politburo Resolution 57-NQ/TW on breakthroughs in science and technology, innovation and national digital transformation.
At the traffic control team under the capital city police department's Traffic Police Division, images from major roads, intersections and bridges are monitored in real time. The locations include Thanh Tri and Thang Long bridges, Nga Tu So intersection, Dam Quang Trung Street and other major corridors.
The cameras are integrated with AI, the traffic control centre and signal systems. They help officers monitor traffic flows, detect violations and identify possible congestion early.
According to the Traffic Police Division, the system operates around the clock. From September 16 to 29, officers monitored key roads and intersections, coordinated with units on the ground, regulated traffic and responded to incidents.
The division manages traffic signals at 564 intersections and maintains 23 green wave routes along major corridors, including Hang Bong, Ba Trieu, Ngo Quyen, Tran Hung Dao, Vo Chi Cong, Hoang Quoc Viet, Au Co-Duong Vuong, Tran Duy Hung, Co Linh and Pham Van Dong streets.
Lieutenant Colonel Bui Thi Thom said real-time camera feeds allow officers to identify where vehicles are accumulating, assess congestion and determine possible causes. Officers can then adjust signals, reroute vehicles or deploy personnel.
Between September 16 and 29, the system identified 7,813 violations, including 3,659 cases of driving in the wrong direction, 3,205 cases of riding without helmets, 389 cases of stopping or parking where prohibited and 265 cases of failing to obey traffic signals.
During the same period, the Traffic Police Division provided or extracted footage on 34 occasions for other Hanoi Police units. The footage supported investigations into security and public order cases, traffic accidents, and violations involving urban order and environmental sanitation.
Accumulated traffic data can help authorities identify recurring congestion hotspots and adjust traffic organisation plans. According to figures released by the city in mid-2026, 39 of 51 congestion hotspots had been addressed, while solutions are being sought for the remaining 12 locations.
Technology is helping authorities move from reacting to congestion to anticipating it. Real-time monitoring enables earlier detection of traffic build-ups, while system data provides a basis for adjusting signal cycles and traffic flows.
The capital is expanding its smart traffic infrastructure. According to information released by Hanoi Police in late September, the city is deploying more than 21,671 AI cameras along 993 major inner-city roads and at 3,129 locations and intersections without traffic signals.
The city aims to complete the transmission infrastructure, installation and peripheral equipment by December 31, making the system ready for operation.
The growing integration of cameras, traffic signals, control centres and data analysis is gradually creating a data-based model of traffic management in Hanoi.
