Monitoring System for Travel Behavior in Urban Area using Mobile Communication Instruments

本研究的目的是探讨我们如何使用移动通信工具来衡量城市空间中的个人旅行行为。它描述了如何使用内置在蜂窝电话系统中的定位技术来确定旅行者在给定时间的位置。关于旅行行为的数据收集有不同的系统概念。确定了系统的特性。为参加旅行和活动调查的个人提供了一个基于小灵通的具有位置定位功能的移动通信设备。当我们打算将这些数据用于城市地区的交通规划和管理时，需要将通过移动仪器获得的定位数据转换为出行行为数据。在此基础上，对数据传输方法进行了阐述，提出了基于定位信息的出行数据管理方案，与传统的基于出行的数据管理方案有所不同。提出了适用于移动对象的数据管理方案。在日本大阪进行了一项试点调查，开发了一种将个人位置数据转移到活动日记中的方法。它涉及十个人参与两周。小灵通系统的定位、数据精度高，预估的出行行为与报告的出行行为一致，可用于未来出行和活动调查的各种数据收集。

The objective of this research is to investigate how we measure individual travel behavior in urban space using mobile communication instruments. It describes how positioning technology that is built into a cellular phone system can be used to determine the location of a traveller at a given time. There are various system concepts of data collection for travel behavior. The characteristics of the systems are identified. A PHS based mobile communication device with a location positioning function was given to individuals participating in the travel and activity survey. The obtained positioning data through mobile instruments should be transferred to travel behavior data when we intend to use those data for transport planning and management in urban area. Then, the data transfer methods are described The data management scheme of travel data with positioning information can bb different from the conventional trip based data management scheme. The data management scheme suitable for mobile object is proposed. A pilot survey that developed a method of transferring an individual's location data to an activity diary was conducted in Osaka, Japan. It involved the participation of ten individuals for two weeks. The accuracy of the positioning, data was sufficient and the estimated travel behavior was consistent with the reported behavior, PHS supported systems will be useful for collecting various data in travel and activity surveys in the future.
