The mutual impact of the vehicles gradually increases with the decrease of the freedom of the vehicles operation in high-density traffic flow.

在高密度交通流状态下，车辆行驶的自由度下降，相互影响逐渐增大，主要以跟驰行驶和换车道行驶为主。

For a high density, when the distance between the intersections is greater than a certain value, the traffic flow maintains constant.

在车辆密度较高的情况下，交叉口间距大于某一值后，交通流量保持恒定值。
