Overview

Background & Policy context

Weigh-in-Motion (WIM) is the calculation of static axle loads (or gross vehicle weights) of heavy vehicles travelling at highway speeds. Possible application areas include:

  1. Vehicle taxation;
  2. Regulatory enforcement / public safety;
  3. Fleet management;
  4. Vehicle condition monitoring;
  5. Point of delivery weighing and billing.

Existing WIM systems can be divided into road-based and vehicle-based solutions. Road-based systems only offer point measurements on a road network, while current vehicle-based systems are expensive and involve long installation times. An ideal solution would be vehicle-based, utilising inexpensive transducers and simple installation processes to create a Real-Time Weigh-in-Motion (RTWIM) system.

Objectives

The objective of the project is to develop and field test a low-cost, wireless system for Real-Time Weigh-in-Motion (RTWIM) of Heavy Goods Vehicles (HGVs).

The system will be integrated with a commercial 'off-the-shelf' (COTS) unit that provides GPS capability and is interfaced to a Geographical Information System (GIS). Forces will be measured using strain-sensitive Surface Acoustic Wave (SAW) transducers mounted on the vehicle axles; these transducers do not require a power supply and are wirelessly interrogated, ensuring simple and fast installation. The integrated system will provide real-time data on loads transmitted to road surfaces.

Methodology
  1. Specification of measurement system;
  2. Sensor design and manufacture;
  3. Interrogation system design and integration;
  4. Preliminary testing and validation; and
  5. Full-scale testing.
