Visual Accessibility Design In Guided Signage System

With the continuous advancement of economic globalization,people move in large numbers between countries and cities.In order to meet the needs of urban life and work,it is very important to create a common good travel environment for different groups of people.How to quickly complete the process of pathfinding in public space,the guide marking system is one of the most important links.However,the design of guiding signs in public space in China is not perfect at present.Especially in the aspect of visual guidance system,although the infrastructure can meet the aesthetic needs of the public,it often ignores the use of special groups,especially the visually impaired.How to better integrate into the social environment and use the public space more safely and freely has become the primary issue facing this group of people.People with visual impairments are mainly divided into blind people and people with other visual impairments who can see.Currently,there are many barrier-free passages for the blind in public space,but other types of visual impairments are not considered.Select the most representative "red and green blind people" as the sample,and conduct systematic analysis and design practice on how they find their way in the public space of the subway station normally,solve the problem of color-blind people travel,and truly realize the visual accessibility of the guidance system.Firstly,through literature research,questionnaire survey,case analysis and field investigation,the visual guidance system of Taiyuan subway station is studied as a whole.Secondly,an in-depth analysis was made from two aspects of visual elements and spatial elements.Field tests were conducted in combination with modern people’s travel habits,and data integration was conducted at the same time to conclude the most suitable visual barrier-free guide design for visually impaired people.Finally,the design practice is carried out for the characteristic subway station--Da Nanmen Station,and the visual barrier-free guide design is actively explored and practiced,which provides some reference for further combing out the barrier-free guide design in public environment space.
