3.1 Mobile Road Overload Control System
The Mobile Road Overload Control System is an important component of the Smart Overload Control Management Information System. It focuses on mobile, temporary, and flexible enforcement scenarios, forming an effective supplement to source-based control and fixed road overload control stations.
Through the deployment of portable weighing equipment, mobile enforcement units, and real-time data transmission technologies, the system enables on-site vehicle weighing, immediate enforcement decision-making, and synchronized data integration with the central management platform. It ensures that overload control measures can be rapidly deployed according to actual road conditions and regulatory requirements.
3.1.1 Application Scope and Objectives
The mobile road overload control system is designed for operating vehicles that are not controlled at the source and fall outside the supervision range of fixed overload control stations. It is mainly deployed at road sections where overloading is likely to occur, providing flexible, targeted, and real-time enforcement capabilities. The system effectively supplements fixed stations and eliminates regulatory blind spots.
3.1.2 System Composition
The mobile road overload control system mainly consists of the following components:
·Portable axle load scales for on-site vehicle weighing
·Law enforcement recording devices for process documentation
·Enforcement vehicles for mobile deployment
·Wireless communication equipment for real-time data transmission
3.1.3 Mobile Enforcement Workflow
Based on alerts issued by the overload control management system or actual road transport conditions, when a vehicle is suspected of overloading on a specific road section, local enforcement personnel establish a temporary inspection checkpoint.
At the checkpoint, portable axle load scales are deployed to conduct on-site weighing. During the inspection process, vehicle-related data—including gross vehicle weight, axle load, axle configuration, license plate information, vehicle photographs, and driver credentials—are collected in accordance with system-defined procedures and transmitted to the management platform in real time.
3.1.4 Enforcement Handling and Disposal
Based on the weighing results:
·Vehicles that comply with regulations are released immediately;
·Vehicles with disputed weighing results are directed to the nearest fixed overload control station for reinspection;
·Vehicles confirmed to be overloaded are required to unload excess cargo in accordance with regulations.
The system automatically generates enforcement records and penalty documents. Drivers or operating entities must complete payment within the prescribed time limit. Vehicles that fail to pay within the required period are entered into the system blacklist and may be subject to further measures such as on-site detention or coordinated enforcement actions.
3.1.5 Portable Axle Load Scale
Equipment Characteristics
The portable axle load scale features a compact structure, lightweight design, and high mechanical strength, making it suitable for frequent mobile deployment and outdoor enforcement environments.
Measurement Performance
The single-platform weighing capacity ranges from 1 t to 30 t, depending on specifications.
·Static weighing accuracy reaches 0.1%–0.3% F.S.
·Low-speed dynamic weighing accuracy, when used with transition plates, is within 3% F.S.
The equipment operates reliably within an ambient temperature range of –20°C to +80°C.
Data and System Integration
The weighing equipment supports wireless data transmission with strong anti-interference capability. Multiple weighing platforms can be flexibly combined to meet different axle configurations. The instrument supports software customization, online upgrades, multiple axle-type selections, and multilingual interfaces, ensuring seamless integration with the overload control information platform.
3.2 Toll Collection System
The Toll Collection System is a key supporting subsystem of the Smart Overload Control Management Information System. It provides standardized and automated tolling services for different road operation scenarios, and supports the coordinated management of vehicle passage, fee collection, and operational supervision.
By integrating multiple tolling modes with electronic identification and backend management platforms, the system improves toll collection efficiency, reduces manual intervention, and ensures the accuracy and transparency of toll calculation and fee settlement. It also provides reliable data support for traffic management, vehicle regulation, and operational decision-making.
3.2.1 Tolling Modes
The toll collection system supports multiple tolling modes to accommodate different road operation requirements:
·Manual toll collection, requiring vehicles to stop and complete payment through cash, bank cards, or mobile payment;
·Semi-automatic toll collection, combining manual card handling with electronic billing;
·Fully automatic Electronic Toll Collection (ETC), enabling non-stop tolling for vehicles equipped with onboard units.
Toll calculation can be configured based on distance, vehicle type, time period, and vehicle weight.
3.2.2 ETC System Operation
Entry Stage
When a vehicle enters an ETC lane, the onboard unit establishes short-range communication with roadside equipment. Vehicle identity information, technical parameters, and account data are securely verified, and entry records are generated.
En-Route Stage
As the vehicle passes ETC gantries, passage time and location information are automatically collected and transmitted to the backend system. The system calculates segment-based tolls according to predefined charging rules.
Exit Stage
At the exit, the system calculates the total toll based on entry data and travel path. The toll is automatically deducted from the bound payment account. Upon successful deduction, exit information is recorded and the vehicle is released without stopping.
3.3 Integrated Application Value
By integrating mobile overload control enforcement with the toll collection system, the platform enables unified vehicle identification, data sharing, and coordinated management. This integration improves enforcement accuracy, operational efficiency, and road infrastructure protection, supporting the construction of a smart and efficient road management system.
