The aim of the project is to review and report on the issue of front, rear and side underrun crashes. In particular this was defined as to:
- Review and collate the findings from major Australian studies examining underrun crashes involving heavy vehicles, including those that were carried out for VicRoads and FORS during the 1990s.
- Carry out a literature review to identify any relevant overseas findings and developments subsequent to these studies including any existing or proposed design standards for underrun protection.
- Produce an updated report on front rear and side underrun that could be used as the basis of a submission to the Federal Government, seeking the introduction of appropriate Australian Design Rules to address the issue of underrun.
Based on the work detailed above, it is recommended that design standards be as follows.
Force application point
|FRONT underrun||Rear underrun||Side underrun|
|outer edges||400 kN||200 kN||1 kN|
|Allowed deflection||as far as possible
and up to 600 mm energy absorbing
|300-400 energy absorbing||30 in front of wheels, 300 elsewhere|
|Style||smooth or flat panels only|
Given consideration of levels of deceleration and the road users under threat, it is recommended that the requirements apply to all heavy vehicles and possibly as low as vehicles of 3 tonne GVM.
