The invention relates to a method for generating a road network map based on bus GPS data. The method comprises the steps that 1, an urban region which needs to generate the road network map is selected, and GPS data of each bus are collected; 2, preprocessing is conducted on the stored GPS data of each bus, and separation is conducted on the GPS data of upstream buses and the GPS data of downstream buses on each route; 3, a road route is extracted; 4, superposition is conducted on the road route through a supplementary mode; 5, repeatability between road sections of the road route is judged, overlap road sections are combined, and an integrated road network map is generated. According to the method for generating the road network map based on the bus GPS data, the more accurate road network map with a clear direction is obtained, and the application of route guidance is facilitated; compared with a traditional map making method, the cost of obtaining data is low, the speed of obtaining is fast; the method for generating the road network map based on the bus GPS data has the advantages of being concise in steps and strong in practicability; the road network map can be rapidly generated through a software program, and a road network structure is updated in real time.
