4.11Devices for delineating and indicating the travelled path#
4.11.1Traffic cones and temporary bollards#
Logos and marking may be used on cones and bollards for identity purposes. When used, it shall be limited to the non-retroreflective surface areas of the device.
4.11.3Temporary hazard markers (T5-4, T5-5, T5-7)#
Replace:
Temporary Hazard markers should be used to show any lateral change of direction of the travelled path through a work site and to delineate hazards and non-trafficable work areas adjacent to the travelled way. They should be erected with their edge about 1 m from the edge of the travelled path and the chevrons should always point to the side to which traffic is required to pass. They should be mounted at about 1 m above the pavement.
with:
Temporary Hazard markers should be used to show any lateral change of direction of the travelled path through a roadworks site and to delineate hazards and non-trafficable work areas adjacent to the travelled way. They should be erected with their edge about one metre from the edge of the travelled path and the chevrons should always point to the side to which traffic is required to pass. Temporary Hazard markers (T5-4 and T5-5) should be mounted at about one metre above the pavement. The T5-7 Temporary Hazard marker is designed to be mounted in 'weighted' temporary plastic or rubber support placed on the ground. The TM5-5A panels are used in a multi-message frame arrangement and mounted at the standard height for a multi-message frame.
The narrow vertical KEEP LEFT sign (R2-3-Q01) may be substituted for the T5-7 Temporary Hazard marker where a regulatory KEEP LEFT sign is more appropriate.
4.11.6Temporary kerbing#
Temporary kerbs may be used at roadworks sites as a means of narrowing traffic lanes. The installation of a kerb changes the environment sufficiently to reduce vehicle speed. Kerbs should be run-over type so that, in the event of an errant vehicle mounting the kerb, the driver is able to control the vehicle. Delineators may be installed with temporary kerbs to guide traffic through the roadwork zone. Where delineators are used, these shall be black and yellow in colour. The bars shall be aligned to point down to the left if vehicles are to pass to the left and shall be aligned to point to the right if vehicles are to pass to the right of the kerb.
