• Abstract:
  This study was concerned with calibrating and testing the gravity model trip distribution using a small sized urban area - Waco, Texas. An analysis of trip purpose stratification was performed, and it was concluded that no practical differences resulted between a seven purpose, a three purpose, and a single purpose model. Upon converting productions and attractions to origins and destinations for purposes of traffic assignment, the single purpose model was seen to differ slightly from the others. The source of this disparity was not definitely ascertainable due to entanglements involving the inappropriate conversion of nonhome-based trips. It was suggested that simply handling the home-based and nonhome-based trips separately as a two-purpose model might be satisfactory.
