| With the rapid development of science and technology and the improvement of people’s living standards,people’s requirements for bus service level are getting higher and higher.Especially in the bus transportation scheduling,passengers hope to get more punctual,efficient and fit the changing rules of passenger flow.Bus service.This paper studies the existing bus dispatching modes at home and abroad,and finds that the existing bus dispatching mode is relatively simple,and it fails to effectively fit the distribution law of the passenger flow to the station.At the same time,the passenger flow direction is not available to the existing tide line.The separation of the characteristics of the balance,as a starting point,this paper has done the following work:(1)Explain the basic theory of bus dispatching,and study the classification of bus dispatching and the problems existing in the current bus dispatching optimization process.Through the analysis of the influencing factors in the bus dispatching process,the content and scope of the passenger flow data survey are determined.The time,space and periodic variation characteristics of the passenger flow distribution are analyzed according to the survey data,and the flexible characteristics are proposed according to different passenger flow characteristics.Sexual bus scheduling.(2)Analyze the cost consumed during the travel process from the perspective of passenger interests and the interests of the bus companies,and construct passenger travel costs under the constraints of bus full load rate,departure interval and adjacent vehicle departure interval.And the public transportation start timetable optimization model with the weighted operation cost of the bus enterprise and the minimum objective function.(3)Select Dalian Bus 1117 as an example analysis object,determine the number of unbalanced vehicles by analyzing and processing the survey data,and then use the MATLAB genetic algorithm toolbox to implement the algorithm for the bus departure timetable optimization model.The optimization results are compared with the 1117 road status table,and the median value is taken in the optimization solution.The results show that the total cost and passenger travel cost are significantly reduced after the optimization,which indicates that the model has certain optimization for the bus interval.The actual reference value. |
