Abstract：

Indoor navigation is difficult in large and complex navigation decision points. Helping occupants navigate more easily in these spaces is one of the important means to improve satisfaction. The navigation sign is an effective and one of the most common ways to achieve this goal. This study aims to propose a novel building information modeling based framework for designing navigation sign layout that better spatially matches the navigation cue demanded by occupants and the navigation cue supplied by signs. The demand for and supply of navigation cues are obtained from the crowd simulation and mathematical modeling, respectively. A programming model is applied to maximize the overlap between them by tuning the location of signs, the orientation of signs, and the navigation texts displayed on signs. To validate the effectiveness of the framework, the entrance lobby of a large hospital is used for the case study. An occupant navigation simulation model and a virtual reality based experiment are used for evaluating the sign layouts before and after implementing the proposed framework. The framework is supported to be effective in reducing the difficulty in navigation and navigation time.
