UTILIZING A GATEWAY CONSTRAINED METHODOLOGY TO BETTER FORECAST TRAFFIC VOLUMES

While unconstrained (demand) traffic projections are very useful in identifying potential future bottlenecks, the overassignment of traffic at the gateways makes operational analyses (i.e., intersection levels of service) inaccurate. Although gateway constrained traffic projections do not completely eliminate the problem of over-assignment, it does provide for a more realistic basis for the analysis. Using unconstrained traffic projections may result in overdesigning arterial roadways, since the projected volumes will actually never be reached. Gateway constrained forecasts reduce the likelihood of overdesign and allow for the formulation of meaningful solutions to realistic future traffic problems.
