time headway meaning in English
车头时距 ，间程
两车相距时差
前后两车相隔时间
Examples
- 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。 - And the deficiencies are pointed out in present researches , such as highway capacity , level - of - service , influence factor of road alignments , etc . from these , it has confirmed that the thesis should be studied from rational analysis , quantitative analysis of level - of - service , impact on capacity of road alignments , setting - up simulation model , etc . the high - accuracy gps dynamic data acquisition appearance is proposed to be used for the first time to carry on the experiment of overtaking on two - lane highways , and experiment scheme is designed according to the driver ' s perceive to judge each overtaking course . based on the experiment data , it can get two important parameters of acceptant gap ? the critical gap of overtakable time headway and returnable time headway through data processing , which can offer the strong support to the research of two - lane highway capacity with qualitative and quantitative analysis . besides , the experiment methods is provided to observe overtaking ratio and to measure the
研究中首次提出了运用高精度gps动态数据采集仪对双车道公路上的超车行为进行观测,设计了根据驾驶员感受度来衡量超车过程的实验方案,并通过后期数据处理得到了超车过程中两个重要的可接受间隙参数-可超车车头时距和可回车车头时距的临界间隙值,为定性和定量分析双车道公路通行能力提供有力的数据支持;同时,还提出了观测超车率的实验方法以及测量加速度干扰的实验方案,统一了计算加速度干扰的时间统计间隔,为双车道公路的服务水平量化研究奠定基础;最后还简单介绍了驾驶员问卷调查法和仿真程序中模型参数标定和验证的数据采集方法。
