Research On The Visual Design Of The Freeway Guidance System

Freeway guidance system is an important part of freeway daily traffic flow control and management, to ensure traffic safety and improve the traffic efficiency plays a vital role. When the vehicle driving in an unfamiliar freeway environment, through traffic signs for drivers to exact,clear, reliable transport the information, to be able to quickly and accurately choose the information of the driver necessity for travel, and through the road traffic signs provide warning information that drivers can easily take the necessary measures, easy to cause the traffic safety problem driving conditions, and prompt traffic signs can be stable, safety, faster perform its functions and effect Meet the needs of drivers for road information, the determining factor for divers can safety, faster, comfortable reaches its destination is freeway guidance system visual design of the scientific nature and rationality. But because of our country freeway construction and development of the time is shorter than the United States, Japan and other developed countries and regions, the study of the theory and the lack of relevant experience for freeway construction, lead to our country, in visual design and setting of traffic signs also have many problems, such as the traffic signs in freeway appeared information overload and traffic sign position setting unreasonable phenomenon such as obscured, these question not only cannot play the role of freeways, will affect the normal operation of the freeway, bring some security issues. To solve these problems, to ensure that freeway play its proper role.First of the thesis for the development background of freeway in our country and at present our country freeway guidance system existing problems research summarize, summarizes the at home and abroad for the different aspects of freeway guidance system the research content, analyzes the research significance and innovative points of freeway guidance system visual design, put forward this thesis the research direction and technical route.Based on this, for freeway guidance system in the freeway and traffic guidance system the related concepts in this thesis, for both have a deep understanding of the concept, then through for traffic guidance system in China and In the developed countries of traffic guide system of the development of the national standard research, then for traffic guide system on the freeway in our country and the foreign developed countries traffic guide system of freeway in the design background and the comparative study on the design concept, Sums up the advanced of traffic guide system in the foreign developed countries, and points out the shortage of our country, on this to grasp a gap between China and foreign developed countries, meanwhile, at freeway guidance system visual design analyzes the freeway and general city road guidance system visual design of differences and features, and put forward building the concept of space visual sense of order. secondly, for guiding freeway guidance system visual design’s driver’s visual characteristics, traffic psychology’s perspective the drivers psychological characteristics and based on cognitive psychology the drivers for the cognitive processes of traffic signs such theory presents an analysis. On the basis of earlier in this article,in freeway guidance system visual design elements conducted detailed comparative study, mastered the condition of the freeway guidance system visual design between China and foreign developed countries, Sums up the advanced of freeway guidance system visual design in the foreign developed countries, and then put forward freeway guidance system visual design improvement propose, based on this Sums up freeway guidance system visual design the basic requirements, then for the development of highway guide system visual design for future the research reviewed.Final dissertation use Guilin Ring freeway Liaotian to Ling chuan as an example of design practice, based on the analysis of the general situation of the road sections, road traffic function and the problems of freeway guidance system visual design for the present, to determine the content of the freeway guidance system visual design and select the liaotian interchange as an example of actually show the effect of guidance system visual design...
