Development of a Complex Network-Based Integrated Multilayer Urban Growth and Optimisation Model for an Efficient Urban Traffic Network

Figure 5

The initial distribution of population, employment, and travel speeds. Here, for each network, 100 nodes are plotted, and the black edges here stand for the travel speeds. (a) The population, employment, and travel speeds are randomly distributed. (b) The population and employment are randomly distributed, but the travel speeds are unified. (c) The population and employment are unified, but the travel speeds are randomly distributed. (d) All of them are uniformly distributed. The colour bar stands for the population amount, the colour of each node can stand for the population and employment amount, and the same is true for the multilayer network representation.
