Reproduction of Net Passenger Trips from Gross Traffic Data

Abstract

This paper proposed a method to reproduce net passenger trips from gross traffic data Net passenger trip data give information of passenger's real origin and destination zones, but involve comparatively large sampling errors due to the detailed questionnaire survey with high cost. Gross traffic data have smaller sampling errors and it can be easily aggregated from ticket data including boarding information. The reproduction model consists of route choice model, gravity model based on relationship between net passenger trips and gross traffic data. The reproduction model was applied to the gross traffic data in 1995, and high reproductive performance wes shown. The reproduction model was concluded to be applicable to estimate lmknown net passenger trips. The net passenger trips in 1970 estimated by the reproduction model showed that long distance trips in 1970 were very few.
