Analysis of Key Commuting Routes Based on Spatiotemporal Trip Chain

Figure 7

Visualization results of the first four clusters during the evening peak hours on June 15 based on the DBSCAN algorithm; the green point denotes the origin point, the blue point denotes the destination point, and the orange line denotes the trajectory. The darker the color of the line, the more the vehicles passing through the trajectory. Clusters are arranged in the descending order of the number of vehicles in them. (a) Cluster 0. (b) Cluster 1. (c) Cluster 2. (d) Cluster 3.
