Abstract
A model is described which reproduces traffic counts on individual links of a rural highway network in response to knowledge of the vehicle registrations and spatial separation of the districts in the region. It was applied to Natal Province to assess its ability to reproduce the traffic counts measured at ten selected points throughout the region. Subsequently the model was used for forecasting traffic flows on twelve roads. Because of its extremely low cost and fast execution time, it is thought that it may usefully be applied in situations where a rapid tentative estimate of future highway flows is needed.
