In order to research overtaking behavior on two-lane highways,the returnable time headway and the overtakable time headway were defined and their critical gap values were attained according to overtaking experiment.
为了研究双车道公路上的超车行为,定义了可回车车头时距与可超车车头时距,通过超车试验得到了两者的临界间隙值;分析了单向、双向车道的最小通行能力,合理解释了双向车道通行能力值小于2倍单向车道通行能力值的原因;最后确定了中国双车道公路上跟车车头时距值和跟车率。
On the basis of substantive investigation and data collection which includes the data of the highway and traffic and accident,the quantitative influence of the accesses on the safety of two-lane highways is analyzed.
在对大量的双车道公路进行了调研和采集了海量的公路、交通、事故数据基础上,针对接入口对双车道公路交通安全的影响进行了量化分析。
Furthermore,the criterion to evaluate two-lane highway alignment consistency was brought forward,referring to that of foreign countries and that of freeways in China.
针对公路线形连续是保证汽车安全行驶的基本要求,以运行车速为中介,提出了相邻路段运行车速相协调的路线设计理念,并参考国外双车道公路及国内高等级公路线形连续性评价标准,提出了双车道公路线形连续性评价标准。
Based on passing behavior analysis,this paper introduced the concept of a dilemma zone(DZ) road segment,where a(vehicle) could not accomplish overtaking or avoid collision with the oncoming vehicle in two-lane highways.
基于超车行为分析,提出了双车道公路超车行为的两难区域概念,在该区域内超车车辆既无法完成超车动作又不能在避免与对向车辆相撞前安全避让。
Vehicles traveling at headways of less than 6 seconds may be taken to be followers on two-lane highways in China.
跟车时间百分比(延误率)是衡量双车道公路服务水平的一个重要指标。
Finally, survey data of two-lane highways in mountainous areas are fitted.
然后,对山区双车道公路实测的车头时距数据进行了拟合,得出了在小交通流量(小于 500 veh / h)时车头时距符合移位负指数分布;阻车时产生的交通流量(大于 600 veh / h)时车头时距符合对数正态分布,该结果能为进一步研究山区双车道公路通行能力奠定基础。
