基于运动空间视觉感知的导向标志布局评价

Motion Space Visual Perceptionbased Evaluation of Navigation Signs’ Distribution

摘要:

采用适用于建筑物内部的凸多边形分割方法对轨道站空间进行分割,提取平均深度值和便捷度2个变量分析行人流线所经过空间的结构系统;根据寻路过程中人的水平和垂直视角构建的立体空间可见视域范围结合寻路流线和流量关系分析运动过程中人的空间感知,建立流线可见度指标,提出轨道站内导向标志布局合理性量化评价分析方法,并结合实例进行应用分析.

关键词:轨道站导向标志; 空间便捷度; 最佳空间视域; 可见空间视域; 流线; 导向标志布局合理性指数

Abstract:

Convex polygon partitioning was adopted to divide the railway station’s space and every divided space was described with depth value and integration value.Finally a quantitative method was given to evaluate the navigation signs’ distribution,which concerned the spatial awareness,the ken of pedestrian,streamlines and their flow.Application of this method with examples was finally given.

Key words:navigation signs; integration value; the best field of vision; the visible field of vision; stream lines; index of navigation signs’ distribution
