摘　　要：为了充分发挥突起路标在圆曲线路段上的线形诱导作用,分析了驾驶人白天视野范围及夜间车灯照射范围内的可视范围,确定驾驶人白天注视弧长和夜间可视弧长随圆曲线半径的变化量,并基于曲率感知和时间韦伯定律,对圆曲线和缓和曲线上突起路标设置间隔进行计算及修正。研究结果表明:突起路标设置间隔的临界圆曲线半径为700m,大于临界半径的圆曲线对应设置间隔为15m,小于临界半径的圆曲线对应设置间隔根据所在半径范围确定;基于速度感知确定车道两侧突起路标应在同一径线上,选取15m设置间隔时,设置在车道分割线的空档中点位置;缓和曲线上的设置间隔与圆曲线上的设置间隔相同。In order to play full use of the linear raised pavement markers＇induction processe on circular curve section,drivers＇visual range during the day and vision field under the vehicle＇s light at night was analyzed.Besides,to determine the change ratio of drivers＇contemplation field＇s arc at daytime and visual field＇s arc at nighttime based on the changing radius length of the curve was determined.Pavement markers＇setting interval on the circular curve and transition curve was calculated and corrected based on the curvature of time perception and Weber＇s law.The results show that the critical curve radius of raised pavement markers＇setting interval is 700 m,setting interval is 15 m when the radius is higher than the critical radius.When less than the critical radius,the setting interval is determined based on the radius range accordingly.Both sides of pavement＇s raised pavement marker should be on the same radius line based on perceptual speed.When setting interval is 15 m,it should be located at the gap＇s midpoint.The setting interval on transition curve is the same as circular curve.6tabs,5figs,12 refs.
