基于人流动线的大型公建导向标识内容自动生成与更新

Study on the Automatic Generation and Upgrading of Signboard Contents in Large Public Building Driven by Passenger Paths

大型公共建筑设计中的导向标识设计关乎使用者的寻路效率与切身体验,其一般基于事先确定的人流动线来进行标识牌的布局设计与内容设计。传统的设计流程中,人流动线的调整会引发后续工作的全部推倒重来;随着建筑规模不断增大、人流动线日趋复杂,人流动线的调整使得导向标识设计成为了1个费时而又易出错的环节,也反向制约了对人流动线、布局设计的变更优化。本文提出的1套导向标识内容设计的自动化方法,它基于Grasshopper编程,可根据设计人员的动线描述、布局定点,瞬间生成或更新近3 000余块的导向标识牌内容。它以上海浦东国际机场卫星厅导向标识系统优化工作为例进行验证,整个过程通过人机互动流程的设计,无缝对接了设计师的工作流程,兼有了人类设计的灵活性与机器算法的效率,为动线与布局设计的优化迭代提供了可能。

The signboard system design for large-scale public buildings is vital to the users’ wayfinding efficiency and experience.Generally,the layout and content of signboards are based on passengers’ paths deliberated by the designers.In the traditional design process,any adjustment of the passengers’ paths will lead to the reworking of all the follow-up procedures.Such design is time-consuming and error-prone due to the growing building scale,path complexity,and sporadic adjustments by designers,which restrains the adjustment and optimization of the path and layout design.This study proposed an automatic signboard content design method,which,based on Grasshopper programming,can generate and update more than 3,000 signboards instantly according to the passengers’ paths and signboard layout set by the designer.Taking the optimization of the signboard generation system in the satellite terminal project of PVG Airport as the case for verification,this paper finds that,through the human-computer hybrid design for the whole process,this system can be seamlessly integrated into designer’s workflow,featuring both the flexibility of human design and the efficiency of the algorithm,and providing insights for the optimization of passengers’ paths and signboards layout design.
