Research On Reasonablle Information About Road Traffic Signs

With the rapid development of the rapid growth of the city of urbanization and economic, road linear various types of more and more, the driver in marching to the sections of the road condition is difficult to identify, therefore, the amount of information needed to provide traffic signs become more and more, more and more big, start can not meet the existing road. Found through research and analysis the effect of traffic sign information quantity threshold of several factors, and found that the current standards for the use of the definition of Chinese characters fonts signs are general, and for the information of single sign of how much the amount of an unreasonable no clear specification, so these are not specified impact mark variable information rationality as an important parameter of this thesis.This paper makes a detailed analysis of the design and manufacture of the signs in the experiment, were set up, three mark Song,Black and Kai font of cards, and every sign of font size and divided into the speed of 40km/h,60km/h,80km/h and 100km/h of the four, also chose a symbol interval of relatively large amount of information Chinese characters designed 7 sets of Chinese characters words, shared AUTOCAD produced 84 different mark experiment for the brand. Then the road modeling tools and Multigen-Creator software to establish the good experimental scene model using, and the 84 sign model to generate.Ive format file after the import scene, bound for Bluetooth development board reaction time data transmission module, and also organized the simulation experiments of these group of model 20 pilots, after processing the data found the most common font reasonable for blackbody traffic signs, and signs the maximum amount of reasonable information card design speed and road have corresponding relationship. The obtained experimental data processing in the conclusion to design a validation experiment, and set up a group of contrast group, used to test the feasibility of the experimental conclusion.
