Abstract
Many transport planning and management tasks require an estimate of the pattern of trip making represented in the form of an Origin-Destination Matrix. This paper describes the practical application of an estimation technique which utilizes only relatively easily obtainable traffic counts. The technique is applied to several practical examples: flights between cities, freeway flows, a commuter rail line, a subway route and two urban streets. In each case, estimates are compared to observed flows in order to afford the reader an impression of the estimation accuracy. (A)
