Research on Design of the Sign System Facilities Design in Urban Public Space—Centered on ‘Micro Design’

As the link of communication between people and environment in urban public space, sign facilities are the ‘eye’ of a city, providing people with the functions of guiding direction, locating .The goal of the sign facilities is to establish a perfect city-guide information system, which is based on the city public space to form the whole city's information identifiability. To give a city a friendly, vivid expression. It can promote urban owners to obtain lifestyle shortcuts and spiritual enjoyment. In this paper, the Sign system facilities of urban public space is taken as the research object. It is found that most of the Sign system designs are homogeneous. Faced with these problems, this paper adopts the method of field investigation and case analysis to analyze the different types of public facilities in Busan and China.From a microscopic perspective, explore the problems of public space guidance system, divide the complex problems, and then solve them one by one to enhance the value of public space guidance facilities. The research on the facilities design of urban public space guidance system is based on the design strategy of "micro-design", which proposes the two aspects of outward representation and invisible image.From the three dimensions of cultural modeling, cultural color and cultural graphics, the "micro-design" modeling of the guidance system is carried out.In urban public spaces, through the integration of visual guidance systems and culture, to deepen the public memory of urban culture and enhance the public image of urban public spaces,So that the guidance design can exert its greater social and cultural value.
