《Transportation Research Part A: General》1987,21(1):39-46
This paper deals with driver behavior while travelling on and merging from acceleration lanes. Two possible groups of drivers were identified: drivers who always perform the merging maneuver during the second part of the acceleration lane, regardless of whether an appropriate gap or lag was available to them previously. Three components of the aggregated delay for the merging process were suggested and evaluated. A method of estimating the random delay and travel time on acceleration lane was proposed and evaluated against an aggregated empirical data obtained on three freeway acceleration lanes. An evaluation of the contribution of the ramp volume to the traffic delay was also performed and discussed and a graph which may be of practical use for road and traffic engineers in assessing the expected influence of various ramp and freeway volume combinations is presented. 相似文献

关于新意法隧道设计的几点建议 总被引:1,自引:0,他引:1
在引进国外先进的隧道修建技术(新意法)时,不应生硬地照抄、照搬,而应在引进和消化吸收的基础上,结合我国的实际情况,不断改进、创新,逐步探索并形成具有中国特色的隧道设计、施工理论和先进、适用的隧道施工方法,以进一步提高我国隧道修建技术水平。文章针对新意法特点,就复杂地质条件下隧道选线、衬砌支护参数的选定及施工方案提出了具体的建议,可为新意法在我国的推广应用提供参考。 相似文献
