The invention relates to a bus departure interval identification method based on bus GPS (Global Positioning System) data, which comprises the following steps of: based on bus GPS positioning data and longitude and latitude of a starting station of each line, screening out GPS records near the starting station, and arranging data of each bus in an ascending order according to GPS positioning time; a DBSCAN (Density-Based Spatial Clustering of Applications with Noise) method is adopted to carry out clustering on the GPS positioning time, and the time period when the vehicle stays at the departure station is identified; the density degree and the dispersion degree of the classes are evaluated by using a silhouette Coeffcient (Silhouette Coeffcient); and selecting the maximum time in each staying time period as the departure time, and calculating the departure interval of each time period. According to the invention, a method reference can be provided for current bus departure interval identification.
本发明涉及一种基于公交GPS数据的发车间隔识别方法,其包括以下步骤:基于公交GPS定位数据与各线路起始站点经纬度,筛选出在起始站附近的GPS记录,并将每辆车的数据按照GPS定位时间升序排列;采用DBSCAN聚类(Density‑Based Spatial Clustering of Applications with Noise)方法对GPS定位时间进行聚类,识别出车辆在发车站点停留的时间段;使用轮廓系数(Silhouette Coefficient)对类的密集与分散程度进行评价;选择每个停留时间段中的最大时间作为发车时刻,计算各时段的发车间隔。本发明可以为现状公交发车间隔识别提供方法参考。
