英文摘要：

Mobile sensing technology based on smartphones is an emerging direction and a hot spot in the field of urban traffic information detection, and it is also an important part of the big traffic data. Relying on the powerful mobile communication technology of smartphones and the environmental perception ability of various embedded sensors, we can obtain microcosmic information,such as real-time position, attitude dynamics of traffic participants, and even traffic scene. In this paper, we reviewed the advances in smartphones based on traffic information acquisition, parameter detection, and information service. We Also discussed the challenges and solutions that the smartphones faced in this field, like energy dissipation, detection data deviation, as well as user＇s personal privacy and security. We also elaborated several future research directions in this field.
