  • Patent number: 10573173
    Abstract: A vehicle type identification method and device based on mobile phone data for solving the problem of providing a convenient and low-cost vehicle type identification method. The method includes: obtaining trajectory data recorded by a mobile phone of a user within a period of time; judging mobile phone users who are on the same vehicle according to the data, and obtaining a vehicle trajectory and the number of passengers corresponding to the vehicle trajectory; obtaining a vehicle origin and destination according to the vehicle trajectory, and obtaining an origin-destination type of the vehicle trajectory in combination with geographic data; obtaining vehicle driving data according to the vehicle trajectory; and obtaining service area data of vehicle staying according to the vehicle trajectory. The cost of obtaining data by using mobile phone big data and by using mobile phone signaling data collected and provided by an operator is low.
