Embodiment Construction
[0029] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0030] The invention provides a method for extracting a shared bicycle skeleton network, the process of which is as follows figure 1 shown, including the following steps:
[0031] S1 builds a shared bicycle network, with bicycle rental points as network nodes, and riding records between two bicycle rental points as edges. The constructed shared bicycle network can be constructed based on existing bicycle riding data, for example, the bicycle riding records in the metroBike bicycle data set or the Niceride bicycle data set can be used. Among them, the bicycle riding record includes the address of the rental point for renting and returning the car, and the time of renting and returning the car.
[0032] S2 calculates the salience of all edges in the shared bicycle network, and keeps the edges with salience greater than zero as the edges of the backbone net...
