Research On Selection And Setting Method Of Directional Sign Information In The Road Net

With the continuous improvement of China's road network structure,the function of direction sign information have changed from guided by traffic flow on a single path to the induction of interchange and coordination of road network.In order to reduce the occurrence of the wrong driver,road traffic signs become more and more important.From the present situation of the highway road network as a whole and the way of information service function,because the science of direction sign set up the lack of necessary theoretical guidance,at present our country road traffic signs of set has such problems as insufficient information of discontinuity.The existence of these problems cannot be ignored,improper selection of highway traffic safety direction sign information poses a potential danger.In this new situation,the demand of the network information is changed when the driver is driving on different roads,and the information search is closely related to the grade and function of the highway.In this paper,on the basis of summarizing the direction sign information set at home and abroad,we analysis of the information of direction sign and functional attributes,when travel with the pilot,in the form of the psychological process of selection of traffic sign information,through the system analysis method,the characteristics of road network under the condition of traffic signs information and has carried on the induction analysis of driving behavior characteristic under the condition of road network is proposed for the basic requirement of traffic sign information,information classification,and release the principle.From the driver in the process before and after the national highway node information search of information search for the driver in the different needs of different stage in the process,obtained by statistical analysis of the highway of different levels of different network forms in China under the guide sign reflects the information selection rules,and find the existing problems.According to the above analysis,under the condition of road network,combined with its functional properties,information index factors such as the intersection of economic development,network with different attributes category corresponding direction sign information stratification and the setting of direction sign and selection rules.According to the factors,which affect the direction sign information selection and the selection method to determine the front of,through the comparison of old and new experiment the effect of direction sign,evaluation analysis and the results of the experiment,hope that through the study of this paper can for our country the direction sign of information in the network Settings and provide method of certain reference for the establishment of related standards.
