Design specifications for diagonal van spots
Develop engineering design specifications for diagonal van
accessible parking stalls.
There is no engineering design available for diagonal van accessible parking,
it has been assumed that the same 8 ft. access aisle is sufficient for diagonal
van accessible parking. There are several reasons this assumption is faulty.
The plan profile of a side lift van must be considered as the angle of the
stall is reduced from 90 degrees. At sharper angles the curb will interfere
with the 8ft. clear space required for a wheel chair to move off the platform
and turn. With very sharp angles and a curb-less design the 8ft. access aisle
is not required and may waste valuable parking space since there is no overlap
of vehicle profiles in adjacent parking spots.
We plan to use upper class engineering students in this project. Colleges available to draw upon are Washington State University Vancouver, Clark College, Portland State University, Oregon Health and Science University, University of Portland, Oregon State University, or University of Oregon.
