1·When it comes to traffic flow — harmony and the highway — they take longer to go through intersections.
每当这种车出现在车流中——它们平和的行驶在公路上——它总是要花更多的时间穿越十字路口。
2·Over the past 50 years researchers have made little progress in developing a general theory of traffic flow.
在过去的半个世纪里，研究人员在形成车流宏观理论方面鲜有进步。
3·It is proved that the fundamental diagram of the average traffic flow speed as the function of the car density for the new model is exactly the same as for fi model.
证明新模型的基本图，即车流渐近稳态的平均速度与道路上的车辆密度之间的函数关系与FI模型的完全相同。
4·With the increase in the Numbers of vehicles, the density of traffic flow is also increased which results that vehicles move with non-uniform velocity on road such as accelerating and braking.
随着汽车的保有量迅速增加，车流密度也在不断提高，汽车在运行时经常处于加速超车、减速制动等变速运行工况。
5·A traffic flow wave theory is used to calculate queuing length according to different crowded level, crowded time and variant demand volume.
按照阻塞程度、阻塞时间及变动的需求流量等已知条件，采用车流波动理论推算排队向上游延伸的最远距离。
