The guide provides detailed discussions of three important, generap 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 t…
Guide to Road Design Part 1 provides practitioners with a detailed description of the critical aspects of road design. This Part includes the design objectives that apply to a road design project, design philosophy, context-sensitive design and the factors that influence the road design, including road design in the context of the Safe System approach, the design domain concept, design phase…
Part 10: Traffic Control and Communication Devices is concerned with the tools that are required for traffic management and traffic control within a network. It covers the various control devices used to regulate and guide traffic, including signs, traffic signals, pavement markings, delineators, and traffic islands. Other devices and technologies that convey information and guidance to road us…
Guide to Traffic Management Part 12: Traffic Impacts of Developmentsidentifies and manages the impacts on the road system arising from land use developments. It provides guidance for planners and engineers associated with the design, development and management of a variety of land use developments. The aim is to ensure consistency in the assessment and treatment of traffic impacts, including ad…
The Guide to Road Design Part 6A: Pedestrian and Cyclist Paths provides guidance for road designers and other practitioners on the design of paths for safe and efficient walking and cycling. The main focus of Part 6A is the geometric design of paths and related facilities such as intersections between paths, and terminal treatments. Detailed guidance is provided on path location, alignment, …
Guide to Road Design Part 4A: Unsignalised and Signalised Intersections provides road designers and other practitioners with guidance on the detailed geometric design of all at-grade intersections (excluding roundabouts). This Part contains information for the design of signalised and unsignalised intersections. Guidance is provided on intersection sight distances, including approach sight dis…
Guide to Road Design Part 6: Roadside Design, Safety and Barriers provides guidance on roadside design and in particular guidance on evaluating the risk of a roadside and the selection and use of road safety barrier systems. Roadsides have to accommodate many features that support the road and the safe and efficient operation of traffic, and have to be designed with regard to environmental req…
Guide to Road Design Part 4: Intersections and Crossings: General contains guidance that provides road designers and other practitioners with information that is common to the geometric design of all at-grade intersections. It contains information on the types of intersections, the road design considerations for intersections and the design process for the development of an intersection layout.…
