Study On Sensitive Information Reaction Degree Of Drivers Of Different Driving Ages

At present,in the daily travel of drivers,the role of the Internet is becoming more and more obvious.More and more drivers will access relevant traffic information through the Internet to determine their own travel path.It is very important to study and determine the sensitive information of drivers of different driving ages and to analyze the response degree of drivers of different driving ages to sensitive information.According to the driver's driving age,reasonable release of different sensitive information and induce drivers to choose their travel routes will play an important role in improving the capacity and service level of road network and alleviating traffic congestion.Scholars mainly study driver's cognitive behavior of traffic information,that is,driver's cognitive model under the influence of multi-source travel information.However,there are few studies on driver's response to different sensitive information under different driving ages and the interaction between driver and road network,especially on the determination of driver's sensitive information under different driving ages.Hardly ever touched upon.Summarizing the existing work,three shortcomings are found: 1.The existing research mainly focuses on the driver's path selection,ignoring the research of information content and the interaction between information and driver;2.There are many kinds of information,but different research groups need to define and classify information reasonably;3.Drivers have different sensitive information because of different driving ages.There are different degrees of response.We should study the degree of information sensitivity of different driver groups according to different driving age.Therefore,in view of the drivers of different driving ages,this paper reasonably distinguishes the types of information,studies the driver's sensitive information and the response degree of driver's sensitive information.The main work is as follows:In this paper,traffic information is summarized,and information screening is carried out according to the research subjects.Then,11 specific contents are determined by clustering method and psychological knowledge,and the content of traffic travel information is clarified.This paper chooses SP method and designs questionnaires according to information content and types.The total number of questionnaires is 200 and 186 valid questionnaires.At the same time,exploratory factor analysis of traffic travel information and correlation test between different driving ages and traffic travel information are analyzed according to thecollected data.That is to say,correlation test is carried out through cross-tabulation and chi-square test,so as to construct structural equation accurately.Determine the key sensitive information of drivers of different driving ages to lay the groundwork.According to the content of Chapter 3,11 candidate factors of traffic travel information sensitivity response are extracted from sample data,and exploratory factor analysis is carried out to determine the principal components.Pearson chi-square test analysis of driver's driving age and ownership information under each principal component category is carried out.However,the determination of key principal components of traffic travel information is not carried out.Therefore,on the basis of the above research,Chapter 4 needs to establish the structural equation model of driver's information sensitive response,determine the key principal components,and determine the key sensitive information of drivers of different driving ages according to the Pearson Chi-square test results of driver and traffic information of different driving ages.Taking the sensitive response of key sensitive information as dependent variable,this paper constructs an analysis model of driver's response degree to sensitive information for different driving age.Then,according to the conclusion of the previous paper,according to different driver's response degree to different sensitive information,in order to improve the efficiency of road network operation,the information release strategy is put forward.
