| Research Abstract |
Travel behaviour models have been highly developed in these years and are able to describe detailed human behaviour. Measurements with high accuracy are now requested to estimate parameters of these modern models, however, traditional survey methods like questionnaire techniques cannot get requested precision because they rely on human capability of memory. Mobile communication tools can be used to collect travel behaviour data with highly accuracy in time and space. These tools, which can measure precise position and record these data automatically, are considered as a new means of travel behaviour surveys.
This study aims to develop and evaluate a methodology of survey of travel behaviour using PHS telecommunication systems, which is a sort of mobile communication instruments. This study consists of three subjects, such as, "Developing and evaluating a position detection method", "Developing methods for obtaining information on travel behaviour from position data", and "Carrying out a

n application of a travel behaviour survey.
A new method of position detection with PHS system has been developed. This method needs no information on position data of base stations, which is needed in previous methods and can be hard to obtain from telephone companies. Precision and other characteristics are examined with a numerical simulation and an empirical study, and good performance has been confirmed.
A method of travel route determination has been also developed. The position data obtained by PHS can have an error which interferes fair route determination with simple methods. This method can estimate a route chosen by a traveller from the position data with poor accuracy.
A concept of "route topology index" has been proposed. This is a tool to find topological characteristics of routes which travellers have taken.
An experiment has been carried out in Kobe Kitano sightseeing area. Numbers of people are hired and asked to get around the area as a normal tourist. PHS terminals are distributed among these subjects and whole trajectories are collected during their wandering. Data are treated with the methods proposed by this study and some interesting knowledge is obtained by this experiment. Less
