On August 22 , the Ministry of Public Security solicited comments on the draft national standards on the system of command, operation, monitoring, and handling of violations of traffic order and safety .

According to the mechanism mandarin Drafting, in recent years, large provinces and cities such as Hanoi, Ho Chi Minh City, Da Nang, Quang Ninh... have actively installed traffic cameras at many key intersections and transmitted data to the traffic light control center.

However, the implementation of smart transportation is currently facing many difficulties, especially data sharing between different agencies and units in the same locality, between localities, and between localities and ministries and branches due to incompatible technology platforms.

Therefore, the Ministry of Public Security allows that It is necessary to study and perfect the standards in the command, operation, monitoring and handling system of traffic order and safety violations.

Camera clearly identifies driver and violation

According to the proposal, the Ministry of Public Security divides the types of cameras into: surveillance cameras, violation detection surveillance cameras, license plate recognition cameras, and traffic measurement cameras, including:

- The surveillance camera equipment must be able to record images and videos that, when magnified, can clearly see the vehicle, the driver's face, and the license plate at a minimum distance of 30m (daytime) and also car slow moving under 5km

- For surveillance cameras that detect violations , they will be divided into two types.

Type 1 will guarantee Online images, recorded video data when magnified can clearly see the vehicle: overtaking in cases where overtaking is not allowed; stopping and parking in violation of regulations; driving a motorbike or scooter onto the highway; driving in the opposite direction of a one-way street; not obeying traffic light signals and other violations.

Type 2 is required to have the following features: monitor, Detect at least one of the following behaviors: driving in the wrong lane or section of the road; overtaking in cases where overtaking is not allowed; stopping or parking in violation of regulations; driving a motorbike or scooter onto the highway; driving in the opposite direction of a one-way street; not obeying traffic light signals and other violations.

Data from type 2 when transmit to monitoring center will include: clear photos and videos of the vehicle, license plate; location, time, violation, license plate identification data; video recording the violation ensures the time before, during and after the violation occurs is determined.

License plate recognition camera required to identify license plates of vehicles to serve the work of detecting violations and preventing crimes on the route . Data transmitted to monitoring center including : Vehicle images and license plate information are guaranteed to be clear.

Outside In addition, there are standards for traffic measurement cameras .

The above types of cameras are required to be able to operate in temperatures of -5 degrees Celsius to 60 degrees Celsius, ensuring IP66 standards or higher (operating well in dusty environments and still being well protected if flooded - PV).

About Speed ​​measuring devices , the Ministry of Public Security divides into the following types: speed measuring devices automatic speed measuring device with recording; automatic speed measuring device with recording using laser sensor technology; automatic speed measuring device with recording using radar sensor technology .

Notably, the automatic speed measuring device with video recording must ensure that it can measure at a vehicle speed range of 8 - 220km/h.

The ability to recognize license plate accurately is greater than or equal to 95% during the day and greater than or equal to 80% at night. The maximum vehicle speed that can capture clear images is greater than or equal to 180km/h.

Applying AI to handle violations

Also in In the recently published draft, the Ministry of Public Security proposed installing an intermediary device (AI Box) to receive signals from cameras to analyze and process data transmitted to the monitoring center.

AI Box is capable of recognizing and detecting at least one of the violations of the Road Traffic Law, identifying license plates and locations of violations.

According to a representative of the Traffic Police Department, the agency recently piloted the use of AI technology to support patrolling and controlling traffic on the route, in order to improve efficiency and avoid overlap.

In the initial stage, this AI application will analyze and recognize vehicle license plates based on photos taken by the phone's camera.

When transmitting images, the data system automatically checks whether the vehicle has been previously inspected by traffic police teams, limiting multiple inspections on the route.

The application also scans the QR code on the citizen identification card, integrating with VNeID to collect driver information.

Thanks to that, traffic police teams can quickly determine whether a vehicle has been previously inspected or not, limiting the need to stop a vehicle multiple times, causing inconvenience to traffic participants.

The Traffic Police Department assessed that the application of technology will help the authorities handle most issues in the process of ensuring traffic safety and order, including handling administrative violations in some areas. This helps to minimize the need for police to stop vehicles directly to control and handle violations.
