Embodiment 1

[0051] figure 1 A schematic flowchart of a bus scheduling method provided by the first embodiment of the present invention is shown. The bus scheduling method includes:

[0052] In step S110, a passenger satisfaction model is constructed according to the relationship between passenger waiting time at a station and passenger satisfaction.

[0053] In this embodiment, the relationship between the passenger waiting time at the station and the passenger satisfaction includes a peak hour satisfaction relationship and a general time satisfaction relationship. In some other embodiments, the relationship between the waiting time of passengers at a station and passenger satisfaction may also include a relationship of satisfaction during periods of low traffic with fewer passengers, and the like.

[0054] Passenger satisfaction needs to take into account factors such as the waiting time at the platform, the degree of congestion in the vehicle, and the inability to board the vehicle ca...

Embodiment 2

[0084] figure 2 A schematic flowchart of a bus scheduling method provided by the second embodiment of the present invention is shown. The bus scheduling method includes:

[0085] In step S210, a passenger satisfaction model is constructed according to the relationship between passenger waiting time at a station and passenger satisfaction.

[0086] In step S220, a cost constraint model is constructed according to vehicle occupancy rate and departure time.

[0087] In step S230, an evaluation function is determined according to the passenger satisfaction model and the cost constraint model.

[0088] In step S240, within the interval of the waiting time, an initialization waiting time is randomly selected, an initial evaluation function value corresponding to the initialization waiting time is obtained, and the initial evaluation function value is used as the target evaluation function value .

[0089] Such as image 3 As shown, within the waiting time interval [t1, t2], an...

Embodiment 3

[0122] Figure 4 A schematic structural diagram of a bus dispatching device provided by an embodiment of the present invention is shown. The bus dispatching device 400 corresponds to the bus dispatching method in Embodiment 1, and any optional items in Embodiment 1 are also applicable to this embodiment, and will not be described in detail here.

[0123] The bus dispatching device 400 includes a first construction module 410 , a second construction module 420 , a determination module 430 and a calculation module 440 .

[0124] The first construction module 410 is used to construct a passenger satisfaction degree model according to the relationship between passenger waiting time at a station and passenger satisfaction.

[0125] The second construction module 420 is used to construct a cost constraint model according to the vehicle occupancy rate and departure time.

[0126] A determining module 430, configured to determine an evaluation function according to the passenger sat...

Abstract

The invention discloses a bus dispatching method, which includes: constructing a passenger satisfaction degree model according to the relationship between passenger waiting time at a station and passenger satisfaction; constructing a cost constraint model according to vehicle load rate and departure time; The degree model and the cost constraint model determine the evaluation function; find the global optimal value of the evaluation function, and determine the optimal departure time interval according to the global optimal value. The invention establishes a quantitative model for passenger satisfaction and cost constraint conditions, adopts an iterative method, and realizes the optimization of passenger satisfaction under the condition that the cost of a bus operation unit meets the limited requirements.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular, to a bus dispatching method. Background technique [0002] In the context of rapid economic development, the scale of cities continues to expand, the travel distance and time of people have increased significantly, urban traffic congestion is serious, and land resources for road construction are in short supply. Therefore, it is of great significance to promote public transportation travel and improve the operation efficiency and service level of public transportation. [0003] During the operation of public transport vehicles, the vehicle operating units hope to meet the operation requirements of the corresponding lines with a larger departure interval and fewer operating shifts; the passengers hope that the waiting time will be shorter and the space inside the vehicle will be more comfortable. For vehicle dispatching, there is a certain contradiction between t...
