Welcome to the Australasian website for weigh-in-motion practitioners.

WIM is the process of measuring the dynamic tyre forces of a moving vehicle and estimating the corresponding tyre loads of the static vehicle. Vehicle mass and relevant information collected from WIM system are crucial for asset management, traffic operations, freight management, safety and enforcement.

This site provides guidance on the management of WIM systems and the data they collect.

It includes reference documents, links to road agency experts, and links to equipment suppliers and overseas websites.


The site is maintained by the Austroads Assets Program on behalf of the Austroads member agencies.
