The PMD also has a steering unit including a steering axle, a fixation unit that connects one end of the steering axle to the footboard unit, and a grip disposed on the other end of the steering axle. The PMD also has a side guard disposed on each side of the footboard unit and extending along an axial direction of the footboard.

A method, implemented by a computer, for determining a position of a personal mobility device (PMD) comprises: estimating a position of a PMD based on a first wireless signal; determining whether the PMD is within an intermediate area between a first area and a second area, based on an estimated position of the PMD; determining whether the PMD moves to the second area, by using both the first wireless signal and a second wireless signal; and determining position of the PMD by using any one of the first wireless signal and the second wireless signal based on a movement of the PMD to the second area.
