METHOD OF TRAVEL DEMAND FORECASTING IN TRANSPORTATION PLANNING. PROCEEDINGS OF THE SRI LANKA TRANSPORTATION FORUM HELD UNIVERSITY OF MORATUWA, SRI LANKA, JUNE 20-22, 1983

The conventional four-stage modelling process is still the most commonly used technique for estimating travel demand. Trip generation -the initial stage of the process is a significant determinant of the form of the final output or the basis for decisions on investment in the transportation sector. Despite the fact that they have received considerable attention over the two decades, the various techniques of trip generation analysis have only marginally improved their predictive accuracy validity and policy sensitivity. The main trip generation analysis techniques are reviewed with respect to their advantages and disadvantages. A more flexible approach that would provide the decision makers with a density of estimated values rather than a single value is discussed. (TRRL)
