Medium-Speed
Weigh-in-Motion (MSWIM)

Measures vehicle weight while vehicles move at controlled speeds.
They offer high efficiency, accuracy, and reliability for
modern traffic environments.

What is a Medium-Speed Weigh-in-Motion System?

An intelligent weighing solution that measures vehicle weight without stopping the vehicle. Unlike traditional weighbridges, trucks do not need to halt completely. Instead, they move smoothly over embedded sensors.

As a result, this system removes the common “stop-and-go” problem. Hence improves traffic flow and increases operational efficiency.

Therefore such systems are widely used on highways, toll plazas, and industrial sites,  because provide real-time data, which is essential for monitoring and enforcement.

Typically, automated vehicle weighing systems operate between 10 km/h and 60 km/h. As a result, they offer a strong balance between speed and accuracy. In addition, they meet the standards recommended by the National Highways Authority of India.

How Does MSWIM Work?

MSWIM systems use high-precision sensors installed beneath the road surface which detect weight as vehicles pass over them.

Because vehicles do not stop, the process remains smooth and continuous.

Step-by-Step Process:

  • Initial Detection:
    As soon as the tires pass over the sensors, the system captures axle loads in real time.
  • Data Transmission:
    Next, the sensors send signals to a controller and the controller calculates the total vehicle weight.
  • Data Recording:
    At the same time, the system records speed, axle count, and vehicle type.
  • Final Processing:
    Finally, the software processes the data and displays instant results. As a result, delays are reduced and traffic congestion is minimized.

Key Features of MSWIM System

MSWIM systems offer several important features for modern logistics:

Features

  • Dynamic Accuracy: Delivers reliable measurements even at varying moderate speeds.

  • Instant Reporting: Real-time data processing allows for immediate monitoring.

  • Robust Build: The durable, weather-resistant design is built to withstand harsh environmental conditions.

  • Seamless Integration: It easily connects with existing traffic management systems to improve overall oversight.

Benefits of MSWIM System

Improved Traffic Flow

Vehicles continue moving without stopping. Therefore, congestion is significantly reduced.

Cost Savings

The system requires less manpower and maintenance. As a result, operational costs decrease over time.

Better Road Safety

MSWIM detects overloaded vehicles early. This helps prevent road damage and accidents.

Smart Traffic Management

Additionally, it supports modern traffic systems and improves overall efficiency.
