State highway planners need to predict traffic generated by oil development and associated activities in North Dakota's oil producing counties, as well as adjacent/associated socio-economic areas including those in Montana and Saskatchewan. Predictions of traffic influences arising from supporting hub "cities" and their associated secondary services are also an inherent need within the process. To aid in this process a forecasting model is being constructed to provide the information necessary to support project selection on both an intermediate and long-range basis.
