Design of "Feature Traffic Sign" and Its Information Measurement

To improve the accuracy and timeliness of information transmission of traffic sign,a design method for "feature traffic sign" and its information quantification way are deeply studied based on the analysis of information transmission principle of traffic sign.The design concept for "feature traffic sign" that was better identified is put forward based on people-oriented sense;Humanized traffic sign that has Tibetan regional characteristic is designed for the highway of Qinghai-Tibet.Then,a theoretical model for feature traffic sign information transmission is established by introducing the traditional theory of visual selection into the information transfer process,a mathematical method for traffic sign information quantification measurement is put forward by using the information measurement method in formation theory.The quantity of information transmitted by ordinary traffic sign and "feature traffic sign" is compared.The results show that the quantity of information transmitted by "feature traffic sign" is larger than that by ordinary traffic sign;the function of information transmission by "feature traffic sign" is stronger and the way of information transmission by "feature traffic sign" is more acceptable within the quantity of 286.3 bit
