Problems solved by technology

[0004] 1) High labor cost
[0005] 2) It takes a long time. Usually, the data collection of a medium-sized city takes a month, so the timeliness of information acquisition cannot be well guaranteed
[0006] 3) The correctness of collection depends on human factors and cannot be effectively verified

Embodiment 1

[0116] figure 1 The flow chart of the method for updating bus line data provided by Embodiment 1 of the present invention mainly includes two stages in the method provided by this embodiment: one is the data collection stage, that is, the bus line data is collected through the bus query service client ; The other is the data analysis stage, that is, the server side calculates and analyzes the collected bus line data to obtain the standard bus line. Such as figure 1 As shown, the method may include the following steps:

[0117] Step 101: When the bus query service client is in the guidance mode, detect the stop point and record the user's running track.

[0118] When the user uses the bus query service client to obtain the bus transfer plan, the bus query service client will be in the guidance mode. Then the user can obtain the bus transfer plan by inputting the origin and destination. Most of these users will take the bus. The bus query service client here may be a mobile ...

Embodiment 2

[0157] Figure 5 The flow chart of the method for updating bus route data provided by Embodiment 2 of the present invention, the difference between this embodiment and Embodiment 1 is that the work of the stop point detection is completed by the server, which reduces the calculation amount of the mobile terminal and has This is beneficial to the battery life of the mobile terminal and reduces the performance requirements on the mobile terminal. Such as Figure 5 As shown, the method includes the following steps:

[0158] Step 501: When the bus query service client is in the guidance mode, record the running track of the user.

[0159] Similarly, the user's running trajectory can be recorded when the bus query service client is in the guidance mode, and the running trajectory of the bus where the user is located can be analyzed. The specific analysis method is the same as that in Embodiment 1, and will not be repeated here.

[0160] Of course, the bus query service client c...

Embodiment 3

[0167] Figure 6 The device structure diagram provided for the third embodiment of the present invention is set on the bus query service client. Here, the bus query service client can be a mobile version of the bus service application, or a bus service application used by users through a browser. Such as Figure 6 As shown, the device includes: a mode determination unit 601 , a track recording unit 602 and a track return unit 603 .

[0168] The mode determination unit 601 is used to determine the mode of the bus query service client.

[0169] The trajectory recording unit 602 is used to record the running trajectory of the user when the bus query service client is in the guidance mode. When users use the bus query service client to obtain the bus transfer plan, the bus query service client will be in the guidance mode, and then the user can obtain the bus transfer plan by inputting the departure and destination. Therefore, the running track of this part of users is recorded...

Abstract

The invention provides a method, a device and a system for updating bus route data, wherein the method comprises the steps of: in a data acquiring stage: when a bus inquiring service client end is in a guide mode, recording a moving trajectory of a user; when a navigation mode is ended or the user arrives at a destination, re-transmitting the moving trajectory to a server end; in a data analyzing stage: classifying the collected moving trajectory by the server end, determining moving trajectories belonging to the same bus route; homogenizing the moving trajectories belonging to the same bus route to obtain a standard bus route; and updating the bus route data by using the standard bus route. According to the invention, data is acquired in real time without using an unprofessional person so that the updating cost is lowered, and the timeliness of updating the bus route data is ensured.

Description

【Technical field】 [0001] The invention relates to the field of Internet application technology, in particular to a method, device and system for updating bus line data. 【Background technique】 [0002] With the continuous popularization of Internet applications and the continuous expansion of information service fields, people's travel is increasingly dependent on navigation systems, such as navigation applications installed on mobile phones, tablet computers and other mobile devices for line inquiries, among which bus Public transportation such as subways and subways is the most common way for the public to travel, so the public transportation query system has become the best choice for users to travel and navigate. It can not only provide users with multiple strategies of bus routes, such as the bus route at the nearest stop, the bus route with the fastest arrival, and the bus route with the least walking, etc. Or provide navigation on how to reach the destination after ar...
