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。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(Vss),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 Vss 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.
