[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] attached figure 1 It is an overall flowchart of the present invention, as can be seen, the invention mainly comprises the following five steps:
[0028] Step 1: collect the basic GPS data of the bus lines, and the data includes the trajectories of the bus vehicles on each bus line, including longitude and latitude. The collected track data of the bus vehicles on the bus line is shown in the following table:
[0029] serial number longitude latitude 1 119.966646 31.791609 2 119.967568 31.79208 3 119.967703 31.792462 … … …
[0030] Step 2: Calculate the distance similarity according to the overlapping factors of the bus lines that affect the calculation of the bus line network density, and remove the repeated sections according to the degree of similarity. The de-duplication problem of bus lines...
