Full title and description

Manual of uniform traffic control devices, Part 2: Traffic control devices for general use — sets out the design, application and installation requirements for regulatory and warning signs, pavement markings and related devices used on roads (including expressway-type roads), and describes how they are applied at intersections, between intersections and at specific situations such as curves, approaches to structures, changes in carriageway width, climbing/overtaking lanes and water crossings.

Abstract

This Part of the AS 1742 series specifies requirements and application guidance for signs, pavement markings, delineation and other traffic control devices for general use on public roads. It includes performance and siting requirements, guidance on advisory speeds and curve treatments, requirements for guide posts and delineators, and typical arrangement diagrams for common road situations.

General information

• Status: Current.
• Publication date: 26 August 2022.
• Publisher: Standards Australia.
• ICS / categories: 93.080.30 — Road equipment and installations (traffic signs, markings and road devices).
• Edition / version: 5th edition (AS 1742.2:2022).
• Number of pages: 283 pages.

Scope

Specifies the characteristics, application and siting of regulatory and warning signs, pavement markings and other devices for general road use. Covers device design, placement and retroreflectivity, pavement marking layouts, treatments for intersections and between intersections, guidance for substandard horizontal and vertical curves, approaches to structures and obstructions, lane changes and dedicated-lane treatments, and additional provisions for expressway-type roads. The Standard provides diagrams, typical arrangements and criteria for advisory speeds and sign selection.

Key topics and requirements

• Design and application of regulatory signs (shape, colour, legends and mounting).
• Warning sign selection and placement for curves, intersections and special hazards.
• Pavement marking types, layouts and application between and at intersections.
• Delineation devices: guide posts, delineators and their siting/spacing requirements.
• Determination and application of advisory speeds on horizontal and vertical curves.
• Requirements for signing and markings approaching bridges, obstructions and changes in carriageway width.
• Retroreflective material and illumination considerations for sign legibility and night visibility.
• Typical installation diagrams and DWG/PDF figure files (supplementary drawing data available with the publication).
• Consistency and uniformity rules aimed at harmonising traffic control device application across road authorities.

Typical use and users

Used by road and transport authorities, traffic and road safety engineers, traffic signal and signage designers, local governments, consultants, contractors, road asset managers and safety auditors to design, specify and install signs, markings and other traffic control devices in accordance with nationally accepted practice.
