Demystifying Extended Design Domain Applications
There are situations where the application of higher order road design principals become impractical or even unachievable due to a combination of constraints.
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.
Content
Trying to understand how EDD should be applied can be a daunting task.
This program offers a solid base for understanding issues such as:
In what situations should EDD be applied
How and why are design parameters chosen
(eg Object Height, Stopping Sight Distance)
Do other factors need to be considered
How do combinations of parameters combine
Are there any ‘show stoppers’ that may preclude the use of EDD
What are the requirements for documentation and legal implications
How is this maze of calculations navigated and what do they all mean
Who should attend?
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
Summary
“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)
