Fitting a transportation solution into the community and environmental
contexts while at the same time satisfying transportation needs is one
of the key - if not the key - fundamentals of Context Sensitive
Solutions. When thinking of how to accomplish this, most designers and
stakeholders refer to flexible design as a solution. Design elements
such as lane and shoulder widths, horizontal and vertical curvature and
sight distances immediately come to mind when one first begins to
visualize how to fit a roadway into its context. What many overlook is
that decisions to widen roadways or upgrade intersections consistently
have more of an impact on a project's footprint. One of the most
significant factors in such roadway expansion decisions are travel
projection modeling assumptions.
