The Austroads Guide to Road Design is intended to provide designers with a framework that promotes efficiency in design and construction, economy, and both consistency and safety for road users.
The guide moves away from rigid design limits as the basis for achieving these goals, and promotes the concept of ‘context-sensitive design’.
The intention is to allow designers the flexibility to exercise their critical, engineering judgement, for example, by choosing design values outside of normally accepted limits when prevailing constraints require, provided that they recognise their responsibility to be able to produce strong, defensible evidence in support of that judgement.
The Guide to Road Design comprises:
- Part 1: Introduction to Road Design
- Part 2: Design Considerations
- Part 3: Geometric Design
- Part 4: Intersections and Crossings - General
- Part 4A: Unsignalised and Signalised Intersections

- Part 5B: Drainage – Open Channels, Culverts and Floodways
- Part 6: Roadside Design, Safety and Barriers
- Part 6A: Pedestrian and Cyclist Paths
- Part 6B: Roadside Environment
