In order to improve railway diagrams, it is necessary to grasp the flow of railway passengers in detail. However, it is impossible to accomplish this goal only by counting the number of on-board passengers. We have developed a method to estimate the passenger flow based on OD (Origin & Destination) matrix data collected from ticket gates in hundreds of stations and timetables of thousands of trains. By analyzing the estimated results, it is possible to obtain the histograms of the number of passengers aboard each train for each destination, the number of passengers boarding and disembarking at each station, the number of transfer passengers at each station and other relevant factors. We have also developed a proto-type system based on this method assuming that all passengers choose shorter time paths. The estimated number of on-board passengers with this prototype system has a strong correlation with the number reported by train conductors. Keywords: passenger flow, ticket gate, OD. 1 Introduction In order to improve railway diagrams or passenger announcement, it is necessary to grasp railway passenger flow in detail including the number of on-down passengers on each train and on-board number per each destination. In Japan, the Ministry of Land, Infrastructure, and Transportation holds the transportation census in order to perceive a passenger flow of public transportation in three major metropolitan areas. Japanese government utilise the census data for planning railway network and public transport operators do for scheduling trains or planning capital investment. The census provides very detailed data of passenger flow because passengers corporate with the survey fill their choice of
