Investigation and development of bridge formulae for inclusion in the performance-based standards

The May 2018 National Transport Commission review of the Australian Performance-Based Standards (PBS) scheme revealed the need to improve the efficiency of heavy vehicle access via the PBS scheme to access substantial national freight productivity, safety and environmental outcomes. The review has found three key elements that are needed to improve the take-up and effectiveness of the scheme. These include providing more certain access, faster access decisions and developing nationally consistent guidelines for bridge assessment. This project is the first step in addressing the proposed reforms and has focused on reviewing the current PBS Tier 1 bridge formulae and identifying issues through analytical review of possible PBS vehicle load effects that can be achieved and through consultation with various road agencies. A review of current infrastructure assessment practices has also been undertaken as part of the project. Three options for future bridge assessment in Australia are presented and discussed in relation to the key Ministerial objectives for the future of PBS access assessment. Gazettal of routes to the current bridge formulae was not supported by the project reference group. The project reference group resolved to recommend that a line model comparison methodology be implemented to drive a nationally consistent vehicle assessment framework. Gazettal of routes to the current bridge formulae was not initially supported by several members of the project reference group. As a compromise a number of state road agencies have agreed to gazette routes for key PBS configurations in the interim, while the line model comparison framework is fully tested and implemented.
