Road Design

Guide to Road Design Part 3: Geometric Design contains guidance that provides road designers and other practitioners with information that is common to the geometric design of road alignments.

Road designers have to consider many factors and disciplines that may affect, or be affected by, the design of roads and intersections. Therefore, reference should also be made to the other parts of the Austroads Guide to Road Design are shown in Section 1 of this guide.

Part 3 covers topics that are common to geometric design such as operating speed, sight distance, horizontal and vertical geometry, including the coordination of those two elements and consideration of cross-section element. It also provides relevant information relating to the design of on-road cyclist and parking facilities.

The information in this guide generally replaces that which was previously provided in the Austroads Urban and Rural Road Design Guides
