WebThe four stages (or four steps) transportation/land use model follows a sequential procedure: Trip Generation. For each discrete spatial unit, it is estimated the extent to which it is an origin and destination for movements. The output is usually the number of trips generated and attracted by a given spatial unit. Trip Distribution.
