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

本研究的目的是探讨如何使用移动的通信工具来测量城市空间中的个人出行行为。它描述了如何将内置于蜂窝电话系统中的定位技术用于确定旅行者在给定时间的位置。有各种各样的系统概念的数据收集的旅行行为。系统的特性被识别。一个基于PHS的移动的通信设备，具有定位功能，提供给参与旅行和活动调查的个人。在城市交通规划和管理中，需要将通过移动的仪器获得的定位数据转化为出行行为数据。然后，描述了数据传输方法。具有定位信息的旅行数据的数据管理方案可以不同于传统的基于行程的数据管理方案。提出了一种适用于移动的对象的数据管理方案。在日本大坂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的方法。它涉及10个人的参与，为期两周。定位的准确性，数据是足够的，估计的旅行行为与报告的行为是一致的，PHS支持的系统将是有用的，在未来的旅行和活动调查收集各种数据。

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.
