The management of the increasing demand on the road infrastructure placed by various road users is one of the most significant issues facing road authorities, network owners and road managers throughout Australia. Performance based standards (PBS) is an initiative of the National Transport Commission that provides a framework for the development and operation of safer and more efficient heavy vehicle combinations. The intelligent access program (IAP) is a unique application of intelligent transport systems (ITS) to heavy vehicle operations with the aim of providing tools that allow the better management of the transport task and the better management of the road assets. The IAP remotely monitors the operation of heavy vehicles to ensure that they are complying with their permitted operating conditions. Queensland is leading Australia in the development of innovative (PBS) heavy vehicle combinations and the introduction of practical, IAP type management systems for the operation of these combinations. Prime mover and quad-axle semitrailer combinations are trialed in Queensland. These combinations meet the PBS requirements and fitted with an on-board mass monitoring system, global positioning systems (GPS) and their operation is monitored by a third party service provider. This project clearly illustrates the benefits of IAP and PBS.
