WEP Traffic projections for 2015
from 1997 Supplemental Draft EIS
note that as gasoline prices increased, traffic levels in Oregon plateaued. Now that we are passing Peak Oil, traffic levels can only go down since you cannot burn fuel that does not exist. After Peak Oil, the economy based on fossil fuel is going to have severe economic problems, if not worse, which will impede the projections of millions of electric cars supposedly replacing our "dependence on foreign oil" (although in Oregon, oil consumption comes from Alaska, which peaked in 1988).
The exaggerated projections in the SDEIS is a reason that local, state and federal governments need to rewrite their assumptions about future traffic levels in order to prepare for an energy constrained future.
