The invention belongs to the technical field of bus route planning, and particularly relates to a bus route and road binding method based on polar coordinate transformation. According to the method, data to be matched with a bus route are obtained, a surface map layer buffer area is obtained through calculation based on the bus route, the surface map layer buffer area and a road network are superposed to select alternative roads and bus routes corresponding to the alternative roads, feature codes of the alternative roads and the bus routes corresponding to the alternative roads are extracted, and the similarity of the two parties to obtain a road which can be bound with the bus route so as to complete the binding of the bus route and the road. According to the method, an annular or arc road can be processed more accurately through polar coordinate conversion, and the influence of sudden change of the angle caused by fluctuation of data near a coordinate axis is reduced. 本发明属于公交线路规划技术领域，具体涉及一种基于极坐标变换的公交线路与道路绑定
