Research On Optimal Method For Combined Dispatching Of ART And Bus

In recent years,ART(Autonomous Rail Rapid Transit),as a new type of medium-traffic road public transport with less investment,shorter construction period,and faster speed,has been gradually introduced into the public transport system of medium-scale cities.On the bus line,it replaces bus to operate independently or co-operates with bus.In the co-line operation mode,how to make a reasonable combined dispatch of ART and bus to protect the common interests of passengers and bus companies has become a technical issue worthy of study.The thesis mainly studies the combination optimization problem of the departure interval and scheduling strategy of ART and bus operating on the same line,aiming to improve the coordination of operation organization of the two modes of transportation and optimize the allocation of transportation resources.The boundary and related elements of the combined dispatching problem of ART and bus are systematically analyzed.In order to solve the optimization problem of the combined dispatch of ART and bus operating on the same line,with the goal of minimizing passenger travel cost and the maximizing operating revenue of public transportation companies,considering the actual factors such as the difference in capacity,travel time,fare difference,first departure time,and passenger congestion costs of these two different vehicles,an optimization model for the combined departure interval of collinear ART and bus under single scheduling strategy and mixed scheduling strategy is established,and an enumeration algorithm based on Monte Carlo stochastic simulation conditions is designed to solve the problem.Through passenger flow sensitivity analysis,the relationship between passenger flow,passenger travel cost,the operating revenue of public transportation companies,and total system cost in different optimization methods is further explored.The case analysis proves that optimizing the combined departure interval and the reasonable arrangement of the first departure time of the two vehicles can reduce the total system cost consisting of the weighted difference between the passenger travel cost and the operating revenue of public transportation companies.The passenger flow sensitivity analysis shows that the greater the passenger flow of the line,the more obvious the optimization effect of the combined scheduling optimization model in optimizing the total system cost.The research methods and conclusions have reference value for the optimization decision-making of the joint operation system of ART and bus.
