Traffic congestion poses significant challenges for rapidly growing cities. Traditional traffic lights rely on fixed schedules and are slow to respond to changing conditions.
Ho Chi Minh City’s new adaptive traffic light system leverages advanced sensors and analytics to enhance traffic flow on major roads.
Project Overview: Adaptive Traffic Control in Ho Chi Minh City
By late 2024, approximately 80 radar sensors had been installed along several of Ho Chi Minh City’s busiest corridors:
- Vo Van Kiet
- Mai Chi Tho
- Pham Van Dong
- Tan Son Nhat airport area
These corridors experience heavy, unpredictable traffic and complex intersections, making them well suited for adaptive signals. The radar sensors deliver reliable traffic data, even during adverse weather or nighttime conditions.
Why radar matters in urban traffic management
Radar sensors offer several key advantages for urban traffic management:
- Operate effectively in all weather and low-light conditions.
- Accurately detect vehicles
- Provide consistent speed and flow data
This enables a dependable, real-time view of intersection traffic, which is essential for AI-based optimization.
How the system works: Detect, Predict, Adapt
Unlike previous systems, this project uses both real and simulated data to predict traffic and adjust signals proactively, preventing congestion before it develops.
- Radar sensors continuously collect data on traffic counts, density, speed, and lane usage. This real-time information is sent to the traffic management center.
- AI models and simulations use this data to forecast congestion 15 to 30 minutes in advance and recommend signal adjustments, such as cycle length and green time. This approach helps reduce queues and maintain steady traffic flow.
Measurable results
The systemreduced vehicle density by approximately 20 percent during peak hours andincreased the number of vehicles passing through intersections by 18 percent. This results in shorter wait times and smoother traffic flow.
Why this matters: efficiency, experience, sustainability
In addition to saving time, the project benefits commuters, reduces idling and emissions, and improves road network efficiency without requiring maintenance Ho Chi Minh City is advancing toward smarter, data-driven traffic management through scalable technology
By integrating radar sensors and predictive AI, Ho Chi Minh City enables adaptive traffic lights that respond to real-time conditions, anticipate congestion, and improve overall traffic. We congratulate LK ENGINEERING on the successful rollout and are proud to support this smart city initiative with robust sensing technology and proven ITS expertise.
