因驾驶者受视觉环境的限制和影响,地下停车库在导向标志的可见性不足,无法高效引导驾驶者进行泊车寻路.在分析导向标志可见域的影响因素基础上,将导向标志的可见域转化为视觉感知机能(水平视角、垂直视角和视距),并进行相关的测量实验,计算出基于视觉感知导向标志可见域的三维立体区域,并对垂直视角进行水平距离转化,最终将三维立体区域转变为平面二维区域,提出了在行车流线上导向标志系统化定位的设计思路.
Due to the limitation and influence of the driver’s visual environment, the underground parking garage can not guide the driver effectively in finding the visibility of the guide signs, and based on the analysis of the influencing factors of the visible area of the guide signs, the guide signs can be seen (Horizontal viewing angle, vertical viewing angle and line-of-sight). Then, the related measurement experiments were carried out to calculate the three-dimensional region based on the visible region of the visual perception-oriented marker. The vertical viewing angle was converted into horizontal distance, The three-dimensional area is transformed into a planar two-dimensional area, and a design idea of systematic orientation of the guide signs on the traffic flow line is proposed.
