Design requirements for 1-level automatic fixed weigh stations in Vietnam from September 10, 2024

Design requirements for 1-level automatic fixed weigh stations in Vietnam from September 10, 2024

The design requirements for the 1-level automatic fixed weigh stations (weigh stations) according to QCVN 66:2024/BGTVT issued with Circular 28/2024/TT-BGTVT are as follows:

- When designing, it is necessary to base on the actual situation on the route to select the appropriate scale location; they should be arranged on major road networks, highways, major road transport corridors, traffic gateways, large cargo origin points, toll stations, branches connected to highways, locations before entering highways, locations where existing infrastructure can be maximized (if any), and other suitable locations that need axle load checking following the actual traffic situation.

- The design location of the weigh stations must ensure safe traffic, have measures to prevent overloaded vehicles from entering the highways (such as arranging branch roads for violating vehicles to move out of the highways, such as arranging camera systems to monitor violating vehicles moving out of the highways); it should be able to control most of the vehicles on the road (including those from neighboring areas, cargo origin points, border gates, ports...), minimizing the phenomenon of overloaded vehicles bypassing via other routes to evade inspection and control by the weigh stations.

- Installation location must ensure appropriate elevation, non-flooding, and minimize situations where subject vehicles evade the scale. There must be design solutions to prevent overloaded vehicles from entering highways, branch roads for violating vehicles to move out of the highways to remedy violations and handle according to regulations.

- There should be solutions to maintain the distance between vehicles to ensure that only one vehicle enters the weighing equipment area per lane to avoid vehicles blocking each other's license plates and skewing weight results.

- Automatic weighing equipment can automatically check parameters such as temperature (if needed), the operational status of each weighing sensor, and detect accurately the position of any damaged sensors (if any).

- The system must be designed with a comprehensive monitoring camera system to ensure the security, orderliness, and safety of the weighing system and installed equipment, as well as the traffic order in the weighing area. The system should also have software to process weighing data with capabilities to automatically generate, send, and store information through the software of the Automated Fixed Single-Level Axle Load Check System and the camera system.

More details can be found in Circular 28/2024/TT-BGTVT which comes into force in Vietnam from September 10, 2024.
