Embodiment 1
[0026] A public transportation big data processing system and method involved in this embodiment are realized through the following technical schemes. The public transportation big data processing system is realized through the scheme, constructing a station sub-network, a line transfer sub-network, and a sub-network of the relationship between lines and stations , based on the provided network computing tools, the dynamic loading of the above three networks is realized to form a station-line composite complex network. There are two types of nodes in the site-line composite complex network, namely, stations and lines, and three types of relationship edges, respectively It is the adjacency relationship between stations, the transfer relationship between lines, and the ownership relationship between lines and stations; nodes and edges have attribute vectors, which represent various attributes of nodes and edges, such as the location, type, and distance between stations , the numb...
Embodiment 2
[0093] The construction process of this embodiment is the same as that of Embodiment 1. The data of bus No. 468 in Qingdao is used to construct a site network. The platform numbers corresponding to the sub-lines of the bus are missing, and some of them are discarded. Some sites lack latitude and longitude coordinates. According to the following Rule completion: If there is a station with the same latitude and longitude coordinates as the missing information station in the station information set, the missing information will be supplemented as the coordinates in the table. If it does not exist in the table, query the latitude and longitude coordinates to supplement. Add IS_ADD data, mark the station whose coordinate information has been changed as 1, and vice versa; the station numbers of some lines cannot correspond to the station numbers of dual programs, and have not been processed yet.

Embodiment 3
[0105] The construction process of this embodiment is the same as that of Embodiment 1, and the line transfer network of Qingdao City is constructed. Network establishment needs to define the node set file and edge set file of the network. The node set file contains node ID and node attributes, and the edge set file contains edge ID, source node, destination node and other information and edge attribute data.
[0106] Table 3-4 gives the reference format for building a line transfer network, and the specific storage format is recommended to be csv format. The content format of the file is not fixed. In the node file, you only need to specify the ID of the node. In the edge file, you only need to explicitly specify the Source and Target attributes of the edge, which respectively indicate the source node and the target node pointed to by the edge. type The attribute indicates whether the network is directed or not, the default is undirected, and it is saved as an undirected edge...
