This paper takes the Visual Wayfinding System of bus stops (diversion guidance system, signage design, bus route map and auxiliary map) in Macao as the research content to analyze inadequacy and improve the design.Taking "semiotics", "cognitive psychology", "wayfinding behavior" and "customer journey" as the theoretical support, as well through the mode of focus groups, in-depth interviews and questionnaire survey, which are qualitative and quantitative methods，this paper focuses on the research of the design about the bus stop wayfinding system. This paper takes the diversion guidance map of the station Praça de Ferreira do Amaral, the bus stop layout of Da Passagem Superior Pedonal Na Rotunda do Istmo, the representative route map of buses, and the auxiliary map as example to optimize the design.The bus stop "Visual Wayfinding System" is a comprehensive spatial information system serving people taking bus. It focuses on the "order design" and "information coding & decoding design" formed by images and symbols, and emphasizes integrity, hierarchy, gradualness and coherence. Based on the five design principles, effective and reasonable design of diversion guidance signs, bus route and bus stop maps will establish a good visual guidance perception for passengers and improve travel efficiency.
