Guide to road design: part 2: design considerations

Part 2 of the Guide to Road Design is the guide's second introductory component, providing detailed discussions of three important, general aspects of design. Firstly, consideration is given to the range of objectives likely to apply to a road design project. These include appropriate recognition of transport demands, safe and efficient traffic operations and achievement of balanced provision for the needs of all road users. Secondly, context sensitive design and the associated concepts of design domain and functional classification of roads are considered, and the vehicular, human and road factors influencing design are discussed. Finally, Part 2 concludes with a comprehensive, tabular presentation of the broad range of considerations affecting road design.
