ABSTRACT
The estimation of future demand for travel under a specific set of forecasted land-use developments and an anticipated transportation plan is considered the backbone of the transportation planning process. In formulating travel demand forecasting techniques, transportation planners had to base their theories on some assumptions or hypotheses. One component of the trip vector that necessitates immediate discussion is the variation of tripmaking over time, that is, peaking characteristics. Early transportation planners recognized the large task of modeling the trip actions of individuals in an urban area and resorted to a variety of methods. Trip generation is concerned with the number of trips produced and attracted to a parcel of land or a zone. The determinants of trips from residences have received considerable attention in transportation studies. Cross classification, referred to as category analysis, is also used for trip-generation analysis.
