摘要
在运动和静止状态下,驾驶员的视觉心理有很大差异。根据驾驶员的动视力、动视野与行驶速度的关系,分析了驾驶过程中驾驶员的动视觉特点。基于驾驶员动视觉的直线长度、平曲线、平面线形组合、平纵组合等公路线形参数,提出了满足动视觉特点的直线长度的合适范围、满足视觉条件的平曲线半径计算公式以及平纵设计中应该注意的问题。
There is a quite difference in the vision psychology of drivers under moving condition and static condition. The relationship of dynamic sight, dynamic field of vision with driving speed was studied, the characteristics of dynamic vision of drivers was analyzed. According to the characteristics, the parameters of highway aligment were researched from the views of line length, horizontal alignment, combination of horizontal alignment, combination of horizontal and vertical alignment. The appropriate length of line was presented, the formula for computing the radius of horizontal curve accord with dynamic sight condition was put forward.
