Asset Management and Pavement Design

The land transport infrastructure network encompassing road pavements and bridges is being constructed and managed to withstand a variety of conditions imposed on it. One of the most important of these conditions is vehicle loading. The Austroads Guide to Pavement Technology Part 2: Pavement Structural Design contains procedures for determining traffic loading for the design of a broad range of…

Road Safety and Enforcement

To ensure that overloaded vehicles do not cause excessive damage to roads, most countries, including Australia, impose axle load limits on vehicles. Successful detection of overloaded vehicles is expected to lead to a reduction in the overall road network rehabilitation and maintenance costs. Weighbridges have been deemed as being too costly to operate, with their fixed location allowing enforcement avoidance.…

Freight Management

Austroads 2000 reported that in terms of freight tonne-kilometres, Australia has the most transport demanding economy of all OECD countries. Overall the growth in travel by articulated trucks exceeds the growth in travel by passenger cars, so that articulated trucks represent an increasing proportion of total traffic. Luk and Chen 1997 reported that WIM data have been identified as a…

Traffic Management and Network Operations

WIM is a major tool used to collect traffic data. WIM equipment provides highway planners and designers with traffic volume and classification data by time of day and day of week. In addition, WIM equipment also provides planners and designers with ESAL that heavy vehicles place on pavements. Motor vehicle enforcement officers use heavy truck axle load data to plan…

Integration with Other Applications

High-speed WIM systems can be integrated with other systems for a range of applications. Two examples are as follows (Austroads 2013): HSEMU this system automatically classifies, measures dimensions (length, height and width) and weighs each vehicle as it passes a HSEMU site at highway speed. In NSW, the unit is used as a screening system. Every heavy vehicle is diverted…
