The fourteen parts of the Guide to Road Design provides valuable guidance to designers in the production of safe, economical and efficient road designs. The Guide covers specific aspects of the design process and deals with the geometric elements of the road, together with drainage and roadside considerations.

Although local conditions and circumstances may sometimes require unique or innovative approaches to design, the bulk of works can be well accommodated by the approach outlined in the Guide to Road Design. The Guide recognises that the design of roads should be based on the capabilities and behaviour of all road users, including pedestrians and cyclists, and on the performance and characteristics of vehicles.
