指示牌的正确放置对公共空间的寻路和信息提供有很大的影响。清晰的可视性，易于理解和有效的放置对于成功的标识都很重要。我们提出了一个标牌可见性分析和优化系统，利用更新的建筑信息模型（BIM）和游戏引擎软件应用程序来模拟行人的运动。BIM可以提供建筑物及其资产的最新数字表示，而计算机模拟环境有可能模拟行人的运动。结合这两种技术提供了一个机会，可以创建一个工具来分析安装的标牌的效率，并在VR环境中将其可视化。该工具包含算法、功能和预定义的场景，用于计算建筑物标识系统的覆盖范围和可见性。该系统帮助建筑管理人员分析（视觉或使用统计）招牌的可见性，评估其适当的放置位置，并优化其放置位置。该方法的适用性已在日本地铁车站的案例研究中得到验证。
The proper placement of signage greatly influences pathfinding and information provision in public spaces. Clear visibility, easy comprehension, and efficient placement are all important for successful signage. We propose a signage visibility analysis and optimization system, utilizing an updated Building Information Model (BIM) and a game engine software application to simulate the movement of pedestrians. BIM can provide an up-to-date digital representation of a building and its assets, while computer simulation environments have the potential to simulate the movement of pedestrians. Combining these two technologies provides an opportunity to create a tool that analyzes the efficiency of installed signage and visualizes them in VR environments. The proposed tool contains algorithms, functions and predefined scenarios to calculate the coverage and the visibility of a building’s signage system. This system assists building managers to analyze (visually or by using statistics) the visibility of signboards, to assess their proper placement, and to optimize their placement. The applicability of the method has been validated in case studies performed in subway stations in Japan.
