Table 3.11.3.3.2.A—Road safety barrier end terminal types and applications Barrier Type Application Benefits Design considerations QTMR MELT Approach end terminal on guardrail. Effective at preventing egress through the guardrail end. Standard end terminal. A flared gating terminal that may requires large clear space; Generally will not fit in an environment QTMR Standard Departure Terminal Used on the departure end of the guardrail with minimal flare from the straight and is ‘tied down’ using a tensioned steel cable. Effective at preventing egress through the guardrail end. Standard end terminal type Requires large clear space; Only a departure terminal. Gating Re-directive Guardrail End Terminals Approach and departure end terminal on guardrail. Tangential guardrail end treatment where there is insufficient space for a flared terminal; Designed for installation on a straight alignment; Available in TL-2 and TL-3 (<100kph) design speeds. Proprietary products; Gating terminal that may require large clear space; Expensive when compared to MELT Non-gating end terminals Approach and departure end terminal on guardrail. A non-gating guardrail end terminal in an environment, Suitable for short lengths of guardrail; May be used back-to-back in medians; Suited to sites where available space for conventional barriers is limited. Proprietary products; Only suitable for roads with a maximum 60kph speed limit Crash Attenuation Terminals Approach and departure end terminal on barriers such as concrete barriers. Are a end terminal; Systems are tested to both Proprietary products; Expensive to install and maintain;
either TL-2 (<70km/h) or (100km/h) design speeds Require large amount of space. Thrie-beam Bullnose A wide arc type terminal made from Thrie-beam barrier Suitable for high environments Require a large amount of space 3.11.3.4 Other barriers 3.11.3.4.A—Other barriers types and applications Barrier Type Application Benefits Design considerations Frangible Timber Bollards Typically in LATM and WSUD schemes, delineation of landscaped areas Decorative Can provide good delineation Will not restrain errant vehicle; Can become hazard itself if struck. Removable and Fixed Steel Post Bollards As for Timber Bollards, Removable Bollard used for access restriction. Removable bollard useful a access point in place of gate; Can be decorative Will not restrain errant vehicle Concrete Bollards Typically in LATM and WSUD schemes, delineation of landscaped areas Decorative; Can provide good delineation. Will not restrain errant vehicle; Can become hazard itself if struck. Log Barrier Fence Park boundary delineation Decorative; Provides good delineation Will not restrain errant vehicle; Easily damaged Guide Posts Road edge or hazard delineation Low cost solution; Easily replaced; Low impact on visual amenity.
