Embodiment Construction

[0055] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0056] like figure 1 As shown in the specific embodiments of the present invention, the following steps:

[0057] (1) obtain the user travel information, including the number of users travel, the earliest expected travel time, the latest planned arrival time, destination location information. Construction and binding shortest path algorithm to optimize the network.

[0058] Select a large service area residents gathered near the bus station point as the initial station, using an index 0 and n + 1 as the initial site two virtual points. The company has a total of K 1 Vehicles owned vehicles, when their own vehicle is insufficient to meet the needs of all users, third-party vehicles were leased to increase customer service capacity. The main difference is that the two types of vehicles: the company's own vehicle from the initial site 0, end-user r...

Abstract

The invention discloses a demand response type bus route optimization method considering heterogeneous vehicles, and the method comprises the steps: obtaining the user travel information, which mainly comprises the user travel number, the earliest expected travel time, the latest planned arrival time, and the destination position information; according to the obtained information, constructing a demand response type bus route optimization model considering third-party heterogeneous vehicles, and determining a target function according to actual demands; solving the path optimization model by adopting a column generation algorithm, and finding a lower bound of the demand response type bus path optimization model by continuously adding new feasible paths to a to-be-selected path set; and carrying out branch operation on the obtained lower bound through a branch and bound algorithm to obtain a feasible solution of the demand response type bus route optimization model, namely a group of demand response type bus optimal routes meeting the travel demand of the user. The method can guarantee the quality of the obtained solution, can effectively reduce the daily operation cost of the demand response type bus, and has a practical value.

Description

Technical field [0001] The present invention belongs to the area of ​​urban public transport, and in particular, the present invention relates to a method of reducing the need for heterogeneous vehicles to reduce operational costs in the operation costs of heterogeneous vehicles. Background technique [0002] Urban public transport is an important means of solving urban traffic problems such as urban congestion, parking issues. In the remote area of ​​urban suburbs, public transportations usually have problems such as low site coverage and sending spaces, which seriously affects the travel of residents in urban suburbs. In order to adapt to regional and residents that have difficulty fully covered by traditional bus systems, the demand response of flexible and convenient features, demand response bus can be supplemented as a traditional bus network, is to solve the "last kilometer" problem of residents. Effective means. Since residents' travel needs typically have fluctuating fea...
