A Combination Scheduling Method for BRT with Variable Interval Departures

Abstract

The invention belongs to the technical field of public transport dispatching and optimization, and especially relates to a BRT (bus rapid transit) combined dispatching method capable of achieving variable bus departure intervals. The method comprises the steps: determining the total number of stops and the total number of bus departure times, and obtaining the driving time of vehicles among stops, passenger flow information, the get-on time of passengers, the get-off time of passengers, and stopping time of vehicles; obtaining the number of get-on and get-off passengers at each stop, so as to determine the type of the stop as a BRT stop or common stop; taking a combination mode and a departure interval as decision variables; building a bus dispatching model, calculating the stop time and the number of get-on and get-off passengers of each vehicle at each stop, solving a target function expression, i.e., calculating the mean waiting time of passengers, the mean on-bus time of passengers, and the mean seating capacity of the vehicles; solving and obtaining a dispatching scheme through employing a particle swarm optimization algorithm, wherein the mean waiting time of passengers and the mean on-bus time of passengers are as short as possible in the scheme, the mean seating capacity of the vehicles are as large as possible in the scheme, and the scheme comprises a departure interval and a departure type.

Description

technical field [0001] The invention belongs to the technical field of public transportation dispatching optimization, in particular to a method for combined dispatching of express buses with variable departure intervals. Background technique [0002] With the rapid development of my country's economy and urbanization process, the number of urban motor vehicles has increased rapidly, and the supply of transportation resources has been seriously insufficient. However, my country's unique "courtyard-style" land use makes it difficult for many areas to be effectively covered by traditional public transportation systems, and there are phenomena such as residential areas, office locations and other activity areas that are far away from public transportation stations such as buses and subways. It is under the guidance of this demand that the concept of "micro-bus system" came into being. By improving the microcirculation inside the "compound" and seamlessly connecting with the su...

Problems solved by technology

[0004] In order to further optimize the combination of BRT buses and ordinary buses and the departure interval between vehicles, reduce the average waiting time and on-board time of passengers, increase the passenger rate of buses, and overcome the existing BRT bus scheduling model that only focuses on vehicles In order to solve the problem of combination mode, the present invention proposes a combination dispatching method of express buses with variable interval departures, including:
