To advise on the recommended practice for the nesting of non-proprietary semi-rigid barrier systems (W-Beam and Thrie-Beam). Refer to manufacturer for nesting details for proprietary semi-rigid guardrail systems.
The launches of the Safer Journey’s initiative and the Decade of Action for Road Safety have brought the way we design for safety into focus. The purpose of this document is to define the Safe System philosophy for dual carriageway roads and how this may vary with context. In particular these guidelines are intended for use on all the roads of national significance (RoNS) projects.
This technical memorandum provides advice on the recommended practice for the design and installation of transitions between wire rope safety barriers (WRSB) and semi-rigid and rigid barrier systems. The barrier configurations in the memo are generic. For specific details for proprietary barrier systems, contact the system supplier.
This technical memorandum provides advice on the recommended practice for the mitigation of hazards associated with tubular handrails commonly installed for pedestrian/cyclist protection adjacent to roadways and on structures. This includes older tubular rail barrier systems on bridges with or without an adjacent footpath.
The Transport Agency temporary concrete road safety barrier design (TCB-1) is a metricated variant of the Oregon State Department of Transport (ORDoT) F-shape “Precast Concrete Barrier Pin and Loop Assembly” (RD500). This is an accepted F-shape public domain temporary concrete road safety barrier system that has been tested in accordance with the United States Federal Highways Administration (FHWA) National Cooperative Highways Research Programme Project 350 (NCHRP350) protocol. This design replaces all other public domain designs for temporary traffic management sites on the State highway network (refer TAN 15-08) unless a specific departure has been granted by the National Traffic & Safety Manager.
