A method for layout of shared bicycle parking area based on clustering algorithm

Abstract

A method for laying out a shared bicycle parking area based on a clustering algorithm, comprising the following steps: S1, obtaining historical location data of a shared bicycle; S2, performing coordinate transformation on the shared bicycle location data; S3, initializing the clustering parameters of the DBSCAN algorithm and performing preliminary clustering ; S4. Use the k-means clustering algorithm to divide too large categories; S5. Calculation of evaluation indicators and inspection of clustering parameter traversal; S6. Propose the optimal location and capacity of the shared bicycle parking area; S7. Determine the stability of the layout effect of the parking area . The method of the invention can effectively alleviate the unreasonable planning of the shared bicycle parking area, arrange the parking area more targetedly, improve the standardized management level of the shared bicycle to a certain extent, and the method of the invention takes into account the location information of different time periods, sharing The service radius of the bicycle parking area and other factors are used to plan the parking area, which can coordinate the parking demand of the whole time and the walking distance of users.

Description

technical field [0001] The invention relates to the field of shared bicycles in urban traffic, and relates to a method for laying out shared bicycle parking areas based on a clustering algorithm. Background technique [0002] As an emerging mode of transportation, shared bicycles are gaining popularity all over the world. Each bike in the shared bike system is equipped with a global positioning system (GPS) and can be rented by scanning a QR code. Users can park rented shared bicycles on bike racks or on the side of the road. This provides residents with an alternative mode of short-distance travel and solves the "last mile" problem of connecting to subway stations. However, these conveniences also bring many problems, such as excess shared bicycles, unreasonable parking and so on. Randomly parked shared bicycles hinder the driving space of pedestrians and motor vehicles. This poses a huge challenge for the government and shared bicycle operators. [0003] Governments a...
