Slide 2 Dr Hans Prem Dr Luan Mai Mechanical System Dynamics Pty Ltd (MSD) Melbourne, Australia

Slide 3 Context NTC funded project; Aimed at increasing PBS take-up; Deliver safe, high-capacity/productivity vehicles; Focus is 20m 6-axle prime mover and semi-trailer; Blueprint design approach; Design flexibility with broad application; Available to everyone at low (no?) cost.

Slide Survey of Motor Vehicle Use (Australian Bureau of Statistics) Number of Vehicles

Slide Survey of Motor Vehicle Use (Australian Bureau of Statistics) Total Kilometres Travelled

Slide Survey of Motor Vehicle Use (Australian Bureau of Statistics) Total Tonne-Kilometres Travelled

Slide 7 Design Goals (6-axle prime mover and semi-trailer) PBS Level 1 Performance/Access; Up to 20m overall length; GML, CML and HML loading and 6.5t on steer; Maximum load space; Based on available equipment; Modularity and interchangeability.

Slide 8 Process Stakeholder consultation; Parameters set to meet industry needs; Define Blueprint envelope; Develop generalised Blueprint design approach; Prepare Formal PBS application.

Slide 9 Outcomes Formal PBS approval; Generalised approach to Blueprint design; Each design is stand alone; One or more designs easy to produce and approve; Support tool (beta version, final testing).

Slide 10 The formal PBS application that underpins this project is complex…
