Practical Applications

Project site selection is outside the scope of this
study; however, access to public transportation is
given specific emphasis in GSA projects. The Site
Circulation Design section of GSA's P100 notes
that "GSA encourages the use of public
transportation among employees and visitors. The
potential need for a bus stop should be considered
early in the design of a GSA building in an urban
setting and should be discussed with planners of
the mass transit system."
