To solve urban area traffic problems, one potential solution is to reduce traffic volumes. In order to do so, a modal shift from conventional passenger vehicles to public transportation and eco-vehicles, including personal vehicles, should be considered. We propose a personal mobility sharing system using the Segway. To evaluate this system, it is necessary to perform experiments under real conditions and gather experimental data for a social pilot study. This study introduces an application for a personal mobility sharing system using the Segway-type vehicle. The main feature of the proposed application is to gather and store experimental data on mobility sharing, and to assist a driver to use the Segway-type personal vehicle safely. Each vehicle is equipped with a tablet, on which the application is installed.
