Inconsistency in the design of traffic barriers for bridges has been identified as a major issue in current practice throughout Australia and New Zealand. The need for standardised solutions has been recognised by road jurisdictions, consultants, and contractors. Key concerns include the determination of appropriate barrier performance levels, structural design criteria, the lack of standard barrier design details, guidance on retrofitting existing bridge barriers, bridge approach barriers and overpass bridge support protection.

To address this, Austroads commissioned a review of the Austroads Standardised Bridge Barrier Design Report AP-R445-13 1 based on current research, guidance, and standards. The project also aimed to verify compliance of bridge barrier designs and guidelines against the relevant Australian Standards that have been recently updated, and the American Association of Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH). To achieve this a comprehensive literature review was undertaken, full scale crash testing was conducted and Finite Element Modelling created and calibrated.
