Glossary of Terms

The first publication in this series; the ‘Glossary of Terms’ with definitions of terms commonly used in the ISWIM best practices publication series. This document is designed to capture the different practices used around the world including some differences in definitions and terms that represent the rich spectrum of WIM practitioners.

WIM Data for Bridge Engineering

The second publication in this series; the use of ‘WIM Data for Bridge Engineering’, What should I know, What should I do? This guide is developed by ISWIM volunteers to assist bridge engineers and inspectors interested in using truck weight and size data collecting by WIM systems. It describes what is considered a good practice in the use of weigh-in-motion (WIM) data for bridge-related applications and assumes no prior knowledge of WIM. The guide focuses on the use of WIM data rather than on the data collection process itself.

There are many ways in which WIM data can be exploited in the bridge community to protect structures, to assess the loading on structures or to estimate the health of structures. Therefore, the guide provides guidance on use of WIM data for:

  1. Bridge design and assessment loading;
  2. Bridge overload protection and;
  3. Bridge health monitoring
  4. WIM data quality management is another important aspect covered in this guide.
