Four Step Travel Demand Model
Travel demand modeling Travel demand modeling aims to establish the spatial distribution of travel utilizing an appropriate system of zones. Modeling of demand is a procedure for predicting what travel decisions people would like to make taking consideration of the generalized travel cost of each alternative. ( The generalized cost is the sum of the monetary and non-monetary costs of a journey. ) The basic decisions making include the choice of destination, the choice of the mode, and the choice of the route. There are various modeling approaches are adopted, but in this blog, we will discuss only popularly known model “four-stage travel demand model” (FSM). The general form of the four-stage model is as follows, Figure : General form of the four-stage modeling
