Research On The Route Planning Method Of Urban Commuter Bus Special Line

In recent years,cities in China have successively opened bus commuting dedicated lines,which have been widely recognized for their convenient and comfortable characteristics.Regarding the planning of commuting dedicated lines,due to the lack of mature theoretical support,the route design mainly relies on experience and lacks quantitative analysis and theoretical basis.Therefore,this article studies the planning method of commuting bus dedicated lines.Firstly,a systematic analysis was conducted on the connotation and operating mode characteristics of commuter bus routes,as well as the influencing factors of commuting mode selection and the basic characteristics of commuting travel.On this basis,the article developed site selection based on demand distribution,and then determined the principles and planning ideas for commuting route planning methods.Then,in terms of site selection for commuting bus dedicated lines,this article establishes a site selection method based on DBSCAN clustering algorithm,which is based on starting and ending point data such as ride hailing and mobile signaling,with variable clustering range,clustering center selection and clustering result evaluation functions.The method for determining the clustering radius,selecting the clustering center,and evaluating the clustering results is proposed.In terms of route planning,this article comprehensively considers the benefits of passengers,enterprises,and society,and establishes a multi-point to multi-point commuter bus dedicated line route planning model.Taking into account the characteristics of commuter bus dedicated lines,the maximum and minimum ant colony algorithm is designed as the model solving method.Finally,a certain area is used as the research object for example validation.The results show that the "multi-point to multi-point" operation mode adopted in this article improves passenger service rate and reduces the total system cost compared to the "multi-point to single point" operation mode;Compared with the basic ant colony algorithm,the designed maximum and minimum ant colony algorithm has faster convergence speed and better solution results;The commuting bus routes generated using the planning method in this article have a more comprehensive exploration scope in the starting and ending regions compared to the actual routes,verifying the rationality of the proposed route planning method and the effectiveness of the solving algorithm.
