Public transport bus exact stop method based on standard line matching

The invention discloses an accurate public traffic positioning method based on standard line matching, which pertains to the filed of dynamic public traffic information collection and is applied to dynamic information release and dynamic scheduling. The traditional method adopts the method of difference, inertial navigation or adding road test equipment to improve the positioning precision, and the equipment cost is increased due to the adding of additional hardware modules. According to the deviation or loss rule of the urban public traffic vehicle-bone GPS collected data, by being combined with the public traffic operation characters and on the basis of not increasing the equipment cost, the invention effectively improves the accuracy of the GPS positioning by being matched with the GIS public traffic line map data with the shape points of high density. The method firstly generates the GIS public traffic line map data with the shape points of high density and accurate stop positions so that the map data is taken as a reference to be used as the foundation for correcting the deviation and filling up the lost data, and matches the real-time collected data with the map data to obtain the precise position information, thus meeting the requirement of public traffic positioning. The method can also be applied to the problem of correcting other positioning information with fixed lines.
