Abstract

This paper is intended to provide valuable references and experiences for the road traffic management department and the sector which formulate the traffic regulations and standards. Based on analysis of the relevant research domestic and overseas, this paper uses the quantitative argumentation mainly and the qualitative analysis as a supplement. It puts forward some concepts about information quantity transferred from highway traffic engineering facilities, mutual information and information entropy. According to the basic elements of traffic engineering facilities, it also builds a basic amount of information computational model which serves for the highway traffic engineering facilities from the angle of the eight types of information (Chinese character information, English character information, Arabic numerals information, Geometric shapes information ,Color information ,Guidance information , Graph or characteristic symbol information and linear facilities information ,et al .Minority characters is not considered temporarily here.). Besides, to analyze the theoretical information content which can be obtained by drivers in the unit road space, this paper proposes a concept called transmission information density of highway traffic engineering facilities and does a case analysis for the component model. The research in this paper has a certain theoretical significance and practical value for improving the service capacity, operational efficiency and safety level of the highway traffic system.
