... For example, uniform distribution (see Fig. 1(a)) or random formation (see Fig. 1(b)) of AVs could be possible options, besides the prevailing platoon formation (see Fig. 1(c)). A closely relevant concept is spatial distribution, and the influence of the spatial distribution of AVs has been recently investigated via theoretical analysis [15] and traffic simulation [16]. However, most existing research considered noncooperative controllers for AVs, e.g., adopting a typical Adaptive Cruise Control (ACC) strategy [17] that is locally designed with no cooperation. ...

... A considerable variety of traffic flow models have been constructed and developed in order to reveal the properties of traffic jams. Generally, these models can be categorized into the microscopic models (e.g., cellular automaton models [2][3][4] and car-following models [5][6][7][8][9][10][11][12][13][14]) and the macroscopic models (e.g., hydrodynamic models [15][16][17][18], lattice hydrodynamic models [19][20][21][22][23][24][25][26][27][28][29]). The macroscopic models describe traffic flow similar to the motion of liquid or gas, while the microscopic models represent individual vehicle's movement. ...
