1Influence of roadway geometric elements on driver behavior when overtaking bicycles on rural roads显示文摘The objective of this research was to determine what influence geometric design elements of roadway may have on driver behavior during the overtaking maneuver.This was part of a larger research effort to eliminate crashes(and the resulting fatalities and injuries) between bicycles and motorized vehicles.The data collection process produced 1151 observations with approximately 40 different independent variables for each data point through direct observation,sensor logging,or derivation from other independent variables.Prior research by the authors developed a means to collect real-time field data through the use of a bicycle-mounted data collection system.The collected data was then used to model lateral clearance distance between vehicles and bicycles.The developed model confirmed field observations that the lateral clearance distance provided by drivers changes with vehicle speed and oncoming vehicle presence.These observations were presented by the authors previously.The model shows that driver behavior can be adjusted by the inclusion,or exclusion,of geometric elements.Evaluating roadways(or roadway designs) based on this model will enable stakeholders to identify those roadway segments where a paved shoulder would prove an effective safety countermeasure.This research will also enable roadway designers to better identify during the design phase those roadway segments that should be constructed with a paved shoulder.Jeremy R.Chapman David A.Noyce 2014Journal of Traffic and Transportation Engineering(English Edition)2014,1,1:10

5166Yb的高自旋态研究显示文摘166Yb高自旋态研究是利用能量为201MeV的重离子熔合蒸发反应124Sn(48Ca,6n)166Yb完成的。通过测量γ—γ符合数据,建立了166Yb的能级纲图。166Yb的转晕带(yrast band)的自旋推到34h,两个负字称带的自旋分别推到33h和34h,并发现了一个新的边带。实验结果表明,在hω=0.37—0.50MeV区间。张兰宽 李广生 杨春祥 J.N.Mo R.Chapman J.C.Lisle 1987中国原子能科学研究院年报1987,,1:0
6奇质子核169Ta高自旋态的研究显示文摘1986年在我院HI-13串列加器上用155Gd(19F,5n)169Ta反应研究了169Ta在束γ谱,建立了三个转动带。在此项工作的基础上我们与英国曼彻斯特大学物理系合作在Daresbury实验室利用122Sn(51V,4n)169Ta反应对169Ta的高自旋态进行了进一步的研究。李生岗 温书贤 杨春祥 R.Chapman D.Clarke F.Khazaie J.C.Lisle J.N.MO J.D.Garrett G.B.Hagemann B.Herskin H.Ryde 1987中国原子能科学研究院年报1987,,1:0
