基于现场眼动实测及虚拟场景的地铁站路径选择实验——以三个广州地铁站为例

An Experimental Study on Route Choice of Metro Station Based on Field Measurement of Eye Movement and Virtual Scene:Case Studies of Three Metro Stations in Guangzhou

文章以三个广州地铁站为研究对象,探讨地铁站内的乘客路径选择模式与环境要素的相互关系。通过在真实与虚拟环境下的寻路实验,采集乘客在地铁站内的空间行为路径数据,并以同步采集的乘客眼动数据作为寻路视觉感知线索的分析依据,基于定性与定量的分析方法,初步构建了地铁站内乘客寻路眼动实验的操作框架及虚拟环境下的寻路实验方法。利用实验数据探析地铁站内标识、亮面、行人特性、交通设施、墙面洞口等因素影响乘客路径选择的基本特征,并分析乘客对目的地的认知与熟悉程度对于路径选择行为的影响。

This paper studies three metro stations in Guangzhou,and discusses the relationship between the mode of passenger route choice and environmental factors. Through the wayfinding experiment in real and virtual environments, the spatial route data of passengers in metro stations are collected, and the eye-movement data of passengers collected synchronously serves as the basis for the analysis of visual perception.Based on the qualitative and quantitative analysis, the operation framework of wayfinding in eye movement experiment and the wayfinding experiment method in virtual environment are preliminarily constructed. By using the experimental data, this paper analyzes the basic characteristics of passenger route choice which are affected by the factors such as signs, lighting elements, pedestrian characteristics, traffic facilities, wall openings, and so on. It also analyzes the impact of passenger’ s awareness and familiarity of destination on route choice behavior.
