Model to Estimate Origin-Transfer-Destination Route Flows and Origin-Destination Segment Flows Across Continental United States


This paper introduces an Origin-Transfer-Destination (O-T-D) model that predicts the route and segment passenger flows between airport pairs using origin-destination (O-D) passenger demand between airport pairs. The model is developed based on a multinomial logit model and covers 443 nodes (i.e., airports) and about 6000 links (flight segments). To create airline schedules between any airport pair, a network-building module has been developed using the Official Airline Guide (OAG) that provides flight segment information. Flight fares for routes are extracted from Airline Origin and Destination Survey (DB1B). The observed segment passenger flows between airport pairs are also obtained from DB1B. Two different types of logit models are calibrated and then validated by comparing estimated route and segment passengers between airport pairs with the observed route and segment passengers obtained from the DB1B and the Form 41 Segment Data (T-100), respectively.
