DEMONSTRATION OF A SIMPLIFIED MODEL FOR SMALL URBAN AREAS

A simple and straightforward method for forecasting highway traffic that was applied in Plaistow, Hew Hampshire, is described. The method requires an external origin-destination survey, demographic forecasts, and good ground counts. No home interview survey or demand model calibration is required. The approach combines a Fratar expansion of external trip tables with a factoring of internal travel on a link-by-link basis to produce a forecast of total automobile travel by link. A unique feature is that the link-by-link factoring of internal travel is directly related to the growth of population and employment in internal zones. This is done by means of an artificial trip-generation and gravity model that requires no calibration. The method produced logical results for Plaistow and appears to have promise for other applications. /Author/
