The invention discloses a city expressway main and auxiliary road floating vehicle map matching method. An initial weight value is calculated by adopting the floating vehicle map matching method based on the weight; the behavior pattern of a vehicle on the expressway main and auxiliary road segments is analyzed and the pattern weight value is calculated; trust degrees of the two weight values are respectively calculated, and data fusion is performed on the basis of the trust degrees so that an integrate weight value is obtained; and the matching road segment of the vehicle is confirmed according to the integrated weight value. The traffic characteristics of the expressway main and auxiliary road segments and the data characteristics of the floating vehicle are fully excavated and utilized so that enhancement of floating vehicle map matching precision of the city expressway main and auxiliary road segments is facilitated and thus support is provided to a road condition information issuing system.
