An Evaluation Analysis on Three-Wheeled Personal Mobility Vehicles

摘要

Personal mobility vehicles are proposed as a new category of transportation device that offers several potential benefits to solve the current problems, such as mobility issues of the elderly, downtown area revitalization, and development of low-carbon transport. This paper aims to explore basic attitude of the general public to understand how people think about three-wheeled personal mobility vehicles. Using the surveys data on i-REAL conducted in Toyota, a discussion is made by employing Quantification Theory and Semantic Differential Method. Moreover, textual data derived from the survey are classified by applying Text Mining. Furthermore, conclusions are drawn and suggestions for further work are made. As a conclusion from the comparative analysis between the unexperienced and experienced groups, the experience brings people to make different evaluations so that the test rides are very important to know the true answers. The analysis on the experienced people shows that the elderly highly evaluated the hobby factors, the male highly evaluated the practice factors and the weather condition seems being a key factor for the current model.
