Barriers between road and rail: barrier adjacent to rail explained

The current standards for road and bridge barriers AS 3845 and AS 5100 assume the main risk of an errant vehicle is to the occupants of the vehicle. In the majority of cases, this is a valid assumption. However, when a rail corridor is parallel to or crosses the road corridor, the risk profile changes. If an errant vehicle crosses the path of a high speed commuter train, the risk profile resulting from the possible death or injury to hundreds of commuters means that a different approach is required to road and bridge barriers to reduce the likelihood of such an event. This paper presents the rationale for developing a risk matrix and a sensible interaction when road and rail corridors are in close proximity. It also outlines a design method for road and bridge barriers related to vehicle type, vehicle weight, road and rail status, effective height, performance levels and site environment. The method was based on a single risk management analysis for both bridge and road barriers. (a) For the covering entry of this conference, please see IRRD abstract no. E218160.
