The Demand for Freight is Increasing
Freight Demand in 2050 will Triple That of 2006

PBS scheme was established in Australia to manage the introduction of non-standard vehicle designs to the fleet, with the aim of increasing the productivity and safety of heavy vehicle operations. Rather than being designed to fit within prescribed length and mass limits applicable to standard vehicles, PBS vehicles are assessed against a number of performance measure to estalblish that they can operate safely and without causing increased damage to road infrastcture.
PBS vehicles must be assessed, approved, built, certified and finally permitted before they can operate on road.

Don’t forget Structures approval in WA required!!!
Explain each
Startability : Ability to commence forward motion on specified upgrade. Level 1 15%, Level 2 12%, Level 3 10%, Level 4 5%
Gradeability: Ability to maintain forward motion on specified grade. Level 1 20%, Level 2 15%, Level 3 12%, Level 4 8%, Level 1 80km/h, Level 2 70km/h, Level 3 70km/h, Level 4 60km/h
Acceleration capability : Ability to accelerate either from rest or to increase speed on road with no grade. Time to travel 100m free rest – level 1 20sec, level 2 23sec, level 3 26sec, level 4 29sec.
Tracking ability on straight path: The total swept width travelling on a straight path. Level 1 2.9m, Level 2 3m, Level 3 3.1m, Level 4 3.3m.
Low Speed Swept path: The maximum width of the swept path in a prescribed 90 degree low speed turn. Level 1 7.4m, level 2 8.7m, level 3 10.6m level 4 13.7m.
Frontal Swing: Maximum width of the frontal swing swept path in a prescribed 90 degree turn. 0.7 and 1.5m
Tail Swing: The maximum outward lateral displacement of the outer rearmost point on a vehicle unit during the initial and final stages of prescribed 90 degree turn.
Steer Tyre Friction Demand: The maximum friction level demanded of the steer tyres of the hauling unit in a prescribed 90 degree turn. 80%
Static rollover threshold: The steady state level of lateral acceleration that a vehicle can sustain without rolling over during turning.
Rearward Amplification: It is the ratio of lateral acceleration of the centre of mass of the sprung mass of the last vehicle unit to the lateral acceleration of the centre of the front axle.
High Speed Transient Offtracking: The lateral distance that the last axle of the rearmost trailer tracks outside the path of the steer axle in a sudden evasive manoeuvre.
Yaw Damping: The rate at which “sway” oscillation decay after a short duration steer input at the hauling unit.
Under PBS scheme, vehicle safety could be improved by assessing dynamic performance of vehicle with safety standard. I am going to cover those safety standards in my next slide.
Better and safer equipment: dedicated combination
Added safety technology: Such as ABS, EBS with rollover prevention technology etc.
Productivity improvements are likely to come from
Number of vehicle to perform the freight task
Fuel used to shift each tonne of freight
Effects on infrastructure – road wear
Reduce traffic delay cost, road construction cost
• increased payloads, by mass and/or volume,
• consequent reductions in the number of vehicle-trips (and driver-trips)
• reductions in the number of vehicles (hence in capital and maintenance costs) and
• more efficient loading and unloading of trucks.
Through PBS scheme Main Roads could promote more innovative vehicles. For example Main Roads has approved 60m roadtrain recently and there are more innovative vehicles in 60m are going to come in near future.
PBS vehicle are eligible to get improved access. For example PBS safety standards of 60m is equivalent to 53.5m. In eastern states PBS 30m has been allowed on 27.5m network and 42m has been allowed on 36.5m network due to their improved performance.
