The AASHTO Guide for the Planning, Design, and Operation of Pedestrian Facilities, Second Edition (2021), provides guidance on planning, designing, and operating pedestrian facilities along and across streets and highways. An introductory chapter presents the purpose and scope of the guide and its relationship to other design guidance. A chapter on planning for pedestrians discusses pedestrian activity and the factors that shape demand for walkable facilities. The design chapter addresses the elements of pedestrian facility design for accommodating pedestrians on public rights-of-way, with methods that vary among roadway and facility types. A further chapter covers pedestrian facility operations and maintenance over the life of the facilities. The guide is intended for roadway designers, planners, and agency staff responsible for pedestrian accommodation on highway projects.
