In order to enhance the attractiveness of urban public transportation and improve the utilization rate of transportation resources, the optimization analysis of conventional bus routes was carried out. Firstly, points of information (POI) were taken as the basic data to analyze the bus routes, establish the POI bearing strength model of the bus routes and describe the relationship between the configuration of the bus routes and the travel demand of the traffic communities. Then, POI bearing strength of bus routes was clustered to analyze the consistency between POI bearing strength of different kinds of bus routes and the travel demand. Finally, the optimization suggestions were put forward combining with the current operation situation of the bus routes. The research results show that the bus routes can be classified through the established model according to the actural situation. This study provides a new idea and method for the optimization of conventional bus routes.
