O-D Proportion Flow Graph on Weekdays. (a)–(d) The ODPFGs with 500m × 500m grid cells in four periods, including nighttime, morning, afternoon, and evening. The maximum trip number normalizes all the connecting edges, and the line width is proportional to the FFBS flow fraction. The size of the dot represents the degree of the nodes. The width of the line represents the weight of the link. It is noted that the proportion flow value is more significant than 0.075. (e) The Jaccard index represents the similarity between two ODPEGs. (f) The Jaccard index varies with the minimum weight of the edge, where the edges with less weight are removed from the network.
