Roads and Maritime Services of NSW (RMS) design, accept and manage barriers for use on classified roads and bridges. Crash testing of a system of barrier units is infrequently performed due to high costs and a myriad of impact conditions that needs…

When adopting the European Standard for road restraint systems EN1317, France faced the need to adapt its National Guidelines in order to allow anti-falling load systems to be qualified and used on its territory. The original French bridge parapets…

The need for higher performance bridge barriers has been reflected in changes in barrier

Vehicular barriers are essential for highway bridges, and are often under the risks of vehicular impact. However, the current highway codes of practice use the force-based design which ignores the inertial resistance arising from the mass of the…

The AS 5100 Standard provides requirements for multiple-performance-level barriers. Historical barriers constructed before 1970 generally do not meet modern requirements for safety. This paper builds on ongoing previous research projects within…

Consistency 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 standard solutions was recognised by road jurisdictions, consultants and…

This paper considers how several recent pedestrian-oriented bridges, all on Auckland’s Western Ring Route, provide new connections or re-establish severed connections between communities. As the architect involved in these bridges, I will also…

Priorities in bridge engineering are changing. The imperative has shifted subtly from minimum cost to “more for less”, requiring a more holistic approach to sustainable delivery which offers best value to the economy and society as a whole over the…

At the 6th Austroads Bridge Conference held in Perth in 2006 a work-shop was convened on bridge barriers. A recommendation from the workshop was to develop a set of guidelines for bridge barrier design. This recommendation was strongly endorsed by…
