The Performance Based Standards scheme enables innovative, designed for purpose vehicles to deliver productivity solutions with the added benefit of setting safety benchmarks.
Performance Based Standards (PBS) scheme applies an alternative regulatory system for heavy vehicles, that limit a vehicle’s mass and dimensions by its performance characteristics and the capability of the road it is to travel on, rather than by fixed mass and dimension limits.
It essentially allows larger or heavier vehicles to get access to parts of the road network which otherwise would not be allowed
PBS achieves higher mass by adding more axles not by gaining more mass on individual axles
The PBS system categorises vehicles into four PBS levels:
The PBS scheme defines:
Some PBS vehicles may require individual assessment against bridge infrastructure before they can be given access to some bridges.
It is important that operators investigate the access issues related to the proposed task before they commence building the vehicle
Once a PBS design has been approved the manufacturer must build the PBS vehicle/combination to the specifications outlined in the design documents.
If the vehicle/combination deviates from the design documents, the variation to the design may need to be re-assessed to ensure it continues to comply with the standards.
The re-assessment process may lead to additional costs and delays in getting the combination on the road.
