These are outlined in the Austroads Guide to Traffic Management, Part 6, Intersections, Interchanges and Crossings (2017). A range of factors should be taken into consideration when deciding the most appropriate traffic management treatment at any given intersection or crossing. It is important for Road Planners and Designers to be aware of the effects that different types of intersection control may have on delays to traffic (under various traffic demand situations) and the resultant emissions. Figures and tables in this Supplement replace those with the same figure or table number in the equivalent Austroads Guide. This Supplement has the same structure as the equivalent Austroads Guide and only additional requirements, clarifications, or practices different from Austroads appear. Where appropriate, this Supplement may also contain additional sections and figures not covered by Austroads, but the numbering sequence found in the Austroads Guide remains. In Western Australia, Main Roads' policies, guidelines and standards take precedence over Austroads Guides and Standards Australia Standards. National Guides and Standards take precedence over International Guides and Standards, unless specifically stated otherwise. This Supplement has been developed to be read as a supplement to the Austroads Guide to Road Design (GRD) Part 4: Intersections and Crossings - General (2017), a copy of which can be obtained via the Austroads website.
