Samenvatting
A means of estimating urban travel is proposed to reduce the time and cost of local transportation planning studies. A trip-distribution model, which is a modification of a gravity model developed by J.C. Tanner of the British Road Research Laboratory, is studied. Origin-destination data are used from a 1962 survey in Pueblo, Colorado (population 108, 243). The ability of the model to simulate the actual travel patterns is based on root-mean-square error analysis.
