On Measuring Equipment Turning Circles
An interesting article on measuring scooter turning circles from the Centre for Inclusive Design and Environmental Access – http://www.udeworld.com/documents/designresources/pdfs/ScootersintheBuiltEnvironment.pdf. Note the drawings to show the turning space required.
How to measure wheelchair turning space is described in my textbook. We received technical advice regarding these measurements from Mr Rod Hunter, an architect in Australia who has had years experience studying this process.
