Guide to Road Design Part 6A: Paths for Walking and Cycling provides guidance for designers and other practitioners on the design of paths for safe and efficient walking and cycling, both within the road corridor and outside the road corridor. The guide provides information on considerations that should be given in providing a path, describes the types of paths and covers the requirements of path users, e.g. operating spaces, factors that influence path locations, and geometric design criteria for a path and related facilities such as intersections between paths, and terminal treatments. Detailed guidance is provided on path location, alignment, width, clearances, crossfall, drainage and sight distance requirements.
The location and design of paths may be influenced by a range of aspects that need to be considered and facilities that need to be accommodated within roadsides. In particular, designers should refer to the Guide to Road Design Part 6: Roadside Design, Safety and Barriers and Part 6B: Roadside Environment.
The design of pedestrian and cyclist paths may also be influenced by design considerations and requirements covered in other parts of the Guide to Road Design. In addition, road designers should also refer to relevant parts of the Guide to Traffic Management in relation to traffic management devices and requirements that may need to be accommodated within a roadside or may otherwise influence the design.
Edition 2.1 has minor editorial and technical changes to Figure 1.1, and Section 2.2 and 5.10.
