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 give full play to the linear induction of the protruding road sign on the circular curve section, the visual range of the driver during the daytime and the illumination range of the night lamp is analyzed to determine the driver's gaze length at night and the nighttime apparent arc length with the curve Radius of the change, and based on the curvature of the time and Weber's law, the circular curve and the curve of the bump on the road signs to set the interval for calculation and correction. The results show that the radius of the critical circular curve is 700m and the circular curve is larger than the critical radius. The distance between the circular curves is less than the critical radius, which is determined by the radius of the circle. Protrusion road signs should be on the same diameter line, select the 15m set interval, set the midpoint of the lane dividing line neutral position; easing curve set interval and circular curve set the same interval.
