There are situations where the application of higher order road design principals become impractical or even unachievable due to a combination of constraints.
“All road design is a compromise between the ideal and what is a reasonable outcome eg in terms of cost, safety, driver expectation, economic drivers, environmental impacts and social issues”
(Transport Association of Canada – adopted by Queensland TMR)
Austroads has provided guiding principles for designers and engineers to enable them to investigate a safe alternative for situations that do not fully fit within the normal design domain guidelines. Extended Design Domain (EDD) offers a robust process with reasonable capability still afforded to the travelling public.
This program has been designed for those involved in the planning and design of roads infrastructure, particularly restoration works and brownfield projects. Attendees are expected to have an in-depth knowledge and practical experience in road design principles.
This workshop is primarily aimed at, but not limited to:Design Engineers, Planners, Technicians, Consultants
The following learning strategies will aim to assist attendees with the implementation of investigative processes, provide guidance for design requirements for what minima can confidently be applied and where additional capability should be provided in order to provide a safe environment to road users.
Lectures, Case studies, Group discussion, In-class activities, Worked examples
Trying to understand how EDD should be applied can be a daunting task.
This program offers a solid base for understanding issues such as:
