A Empirical Research on Movement Grasp in City used of Mobile Telecommunications Technology

Abstract

As for the action investigations of the city planning and the transport planning, etc. at the plan stage, there were a lot of investigations by the questionnaire form of the paper base that centered on the persontrip investigation now. In these methods, problems of the load increase and the cost increase, etc. to accuracy and a character and an immediate object person existed. On the other hand, the progress of positional specific technologies such as the pedestrian navigations and GPS (Global Positioning System) by the cellular phone and PHS is remarkable because of a rapid improvement of information and the communication technology in recent years. The purpose of this research is considered the possibility such as the specification of securing and the transportation of accuracy in various places of those who act by the movement in the city from a variety of investigation results by using those positional specific technologies and exists in the examination of the feasibility. As a result, in mobile telecommunications information on which the cellular phone and PHS depend though there is a limit on accuracy. And it turned out that accuracy was able to improve by using GPS and D-GPS together. In addition, it is the one to search for the possibility to the evaluation of the best arrangement of facilities in the city through the analysis of the acquisition data.
