high-density traffic flow 公交调度
high density of traffic flow 交通流高密度
If the traffic density increases much above that, the flow pattern begins to become unstable.
如果车辆密度大幅高于上述数字，则车流模式开始出现不稳定现象。
First is free flow in which the density of traffic is low enough to allow vehicles to travel at the maximum speed allowed.
首先是畅通无阻，交通密度足够低，使得车辆能以最高时速行驶。
Initially set velocity, density of traffic flow, traffic volume of service and the rate of traffic load as the measurement indicators.
对航道服务水平进行定义，并初步确定速度、交通流密度、服务交通量和交通量负荷比等四项度量指标。
