With the popularity of smartphone, user¡¯s location information is of great interest as mobile apps based on the location information are increasing. In this paper, we are interested in analyzing user¡¯s speed data based on the location information. It is not uncommon to observe locations with great measurement errors, removing them is necessary. The distribution of speed can be considered as a mixture model in accordance with transportation means. We identify a tail part as a component of a mixture model and fit a simple parametric model to the tail part of the speed distribution.
