摘要
为确定高等级立体复合通道可变信息标志的安全布设间距,基于狮子洋通道设计方案开展了驾驶模拟试验.试验选取了相邻路段车速差值、运行车速与设计车速差值、车速降低系数为分析指标,共采集30名驾驶员的试验数据.结果显示,不同布设间距会影响驾驶员对行车速度的决策,从而对行车安全性产生影响,其中2 km间距方案对速度影响相对平顺,安全性较高.
Abstract
To establish the safe spatial configuration of VMS within high-class three-dimensional composite passageways,a driving simulation experiment has been designed based on the Shiziyang Link Project.In this experiment,the difference in running speed between adjacent road sections(△V85),the variance between operating and designed speeds of the same road section(△V),and the Speed Reduction Coefficient(SRC)are selected as analytical indices,and the experimental data of 30 drivers are collected.The results show that the △V85 and △V of different layout spacing schemes are significantly different,and the degree of driving safety is different.The results show that the 2 km spacing scheme has a relatively smooth effect on speed and with high safety.
