车头间距 meaning in Chinese

space headway

The time headway distribution of the simulation system based on this model can be tuned by two simple parameters , so it can accord with different time headway distribution rule in condition of practical unsaturated traffic
基于该模型建立的仿真系统，凭借两个简单的参数来调节不同车速的期望车头间距，使车头时距分布规律符合交通未饱和时车头时距的具体分布情况。
The model assumes that every vehicle tends to keep expected time - headway and each vehicle synchronously updates its velocity by estimating the velocity of the head vehicle , the distance headway and the probability of random slowdown
该模型假定行驶车辆都趋向于保持一个期望的车头时距，通过对前车速度和车头间距的估计，并考虑随机减速的影响对车速进行同步更新。
The change rule between headway and space headway of three phases were analysis , and the statistic model of headway and space headway with following car speed were gain . the expectation space headway in different speed under special tr
验证了稳定跟车状态存在期望车头间距，实测数据显示，期望车头间距受车速的影响，并获得了特定交通条件和道路条件下不同速度所对应的期望车头间距。
