CN EMPTY FLOW MODEL

Given a forecast of loaded car movements for some future year, this computer program predicts the induced empty car traffic for the many origin/destination pairs of the CN network. In this gravity model, the number of empty trips between an origin and a destination is assumed to be proportional to the cost on arcs, the production at origins, and the attraction at destinations. The Furness procedure is used as a basic tool for the calibration and the prediction phases.
