The Research On Operating Lines And Scheduling For Responsive Feeder Transit Under The Mixed Operation Mode

It is difficult for residents to finish" The First and Last Kilometer" when they travel by Public Transit,and it's a common phenomenon.To solving the problem above,the Responsive Feeder Transit(RFT)served at the Arterial Bus station was proposed.As an effective supplement of the Arterial Bus,the vehicle routes,departure time,and responsive stop of the RFT are determined by passenger's demands,which has great flexibility and can implement door to door service services.So far,the research on RFT is getting deeper,and its application is gradually popularized.There are two types feeder passenger at the Arterial Bus station,the first one types are these who get to nearby location from the Arterial Bus station,and the second one types are these who get to the Arterial Bus station from nearby location.In order to fulfilling travel demand of the two types passenger,the vehicle operation mode was adopted to pick up passengers to the transfer station separately and deliver passengers to the nearby location separately.This single vehicle operation mode has low load rate and high repetition rate in path,which is not conducive to develop efficiency of the RFT.Therefore,the RFT under mixed operation mode of simultaneous pick-up and delivery was taken as research object,and the routing and scheduling optimization problem of RFT were researched in thesis.The main research contents of this thesis including:The related research of RFT for the past few years were reviewed,and the deficiencies of these research were discussed.Combining the advantages of mix operation mode of vehicles,the RFT routing and scheduling under mix operation mode was studied.First,the vehicle route representation method based on-board passengers rather than demand points was devised,which can reflect the personalization of passenger travel time window.The route representation of this method is simple and can also effectively reduce repeated routes.Then,the system objective function is constructed by combining the costs of vehicle departure and travel,the penalty costs of vehicle early and late arrival,and passenger fares.The optimization and coordination model of departure time,vehicle type and route was constructed,which is aim at minimizing the system cost.At the same time,in this model,the vehicle capacity,passenger time windows,vehicle running time were all taken as the constraints.The algorithm was designed to solve the coordinated optimization model.A method based on the integrated coordination optimization model was put forward to calculating the optimum service scope.The method to determine the service scope was based on the principle of capacity and demand equilibrium.At last,the examples were given to explain the theory.First,an application scene was designed to verify the superiority of the integrated coordination optimization model,and the results show that under the same passenger demand situation,compared to pick-up and delivery separately operation mode,The mixed operation mode can significantly increase the utilization rate of seats,and also significantly reduce system total costs,vehicle population in the parking lot,vehicle departure times,and average vehicle miles required to transport unit passengers.The advantages of the mixed operation mode are obvious.Then,a case study was given to explain the method of best service scope,and the consequence proved that the method proposed for determining service scope is feasible.
