BRIDGE APPLICATIONS OF WIM DATA

This paper discusses the application of vehicle weigh-in-motion (WIM) data to bridge design and management. This is illustrated by results obtained from analysis of data collected in Australia and Canada. The paper presents the analysis techniques available to post-process WIM data. The concept of a Bridge Site Index to facilitate the ready comparison of sites and trends is discussed. The index is independent of span. Also presented are methods of ensuring optimum value from WIM data and the appropriate methods of reporting and communicating this to those who use the data.
