Study On Using Optimization And Evaluation Methods Of Variable Message Signs For Highway

Since the Chinese Economics Reform,China has involved in a rapid economic development,and it also promotes the rapid improvement of urban transportation mechanization.More cars use brought a lot of traffic problems,such as traffic congestion,traffic safety and traffic pollution.Vigorous development of ITS techniques have improved the traffic information supply,auxiliary better driving performs is the effective way to solve the problem of numerous traffic.To set up the highway variable message sign is one of important methods.Variable message sign papers for highway use of optimization and evaluation of research,in order to further promote the highway variable message signs a wider range of applications.First of all,the papers at home and abroad on variable message sign and variable information highway sign paper summarizes research results and practical application case experience,points out the layout and display in variable message signs on international graphic design research is more,but less for running and evaluation research,and in the early stages of exploration.Summarizes the future research of variable message sign to daily management and setting up the evaluation after development,provide a reference for further research.Secondly,the paper analysis the characteristics of variable information highway sign,through the study of category variable information highway signs,set up the principle,composition and function as well as technical features to depict the highway and variable message sign in view of the traditional static traffic sign and marking the difference between other types of transportation information prompt,foreshadowing for papers subsequent chapters.Then,this paper studies the variable information highway sign using optimization method,by analyzing the information of the driver for variable message sign to accept mental process,put forward the readability of variable message sign visibility,details,color,display content,as well as release scheme optimization.On this basis,study the evaluation method of highway variable message sign,variable information from highway signs of social economic evaluation,technology to improve the evaluation and benefits through the analysis of the influence factors,puts forward the evaluation system of highway variable message sign and the corresponding evaluation model is establishedFinally,the paper analysis with Yongjiang highway as an example,summarizes the variable message sign Yongjiang highway operation status and the existing problems,and puts forward the solution to the problem,put forward the application of variable message sign Yongjiang highway optimization to improve the method,and factor of influence on the benefit of the Yongjiang highway made the evaluation and the evaluation results are obtained.
