Study On Coordination Of Rail Transit And Regular Bus Operation

The development of public transport is very important for urban rail transit and regular bus coordination.This article will proceed from the perspective of reasonably setting the departure interval and calculating the departure interval,aiming to use the point of reasonable coordination and coordinated management to coordinate the urban rail transit with the regular public transport,so as to reduce the passenger travel time and reduce the total cost of the system.First of all,the dissertation describes in detail the research background of the development of urban rail transit in China,the research background of operational coordination and the research on the coordination of public transport operations at home and abroad,and proposes the purpose and significance of the operation coordination of this paper,as well as the research content and technology roadmap of this paper.At the same time,this paper analyzes the coordination of urban rail transit and conventional bus operations from the two modes of traffic classification and basic characteristics,the classification of coordination,the connotation,characteristics,roles,and principles of operation coordination,and proposes the coordination of urban rail transit and conventional bus operations in this paper.The specific method.Then,an operation coordination model was established with the minimum total cost of the system as the objective function.The model mainly uses the matching of rational transport capacity and the arrival of passengers,the uniform distribution of public transport vehicles to the station,the satisfaction of passenger flow requirements that public transport vehicles can meet,and the fact that passenger flow remains unchanged during the study period.The coordination of public transport operations can be achieved by optimizing the departure intervals within the peak hours of each line.Among them,the total cost function of the system established in this paper mainly includes the operating cost of public transport companies and the cost of passenger travel.The operating costs include the operating costs of urban rail transit companies and the operating costs of conventional bus companies;passenger travel costs include passenger walking costs,passenger in-car costs,passenger waiting costs,and passenger transfer costs.Finally,the genetic algorithm was used to solve the operational coordination model.The model and application of operational coordination were analyzed with a single urban rail transit route and public transportation network.This paper selects the public transportation network for model application research and uses Guangzhou Metro Line 3 and some important transfer bus lines for case analysis.The genetic algorithm is used to obtain the optimized rail transit and departure interval results of each transfer bus line.At the same time,the total operating cost function is used to calculate the minimum total operating cost,and the total cost of the total operating cost,transfer cost,and waiting time.Cost and cost in the car.
