| The occurrence of traffic accident is mainly because of the driver's obligation. An important reason is that the driver couldn't judge the safety speed correctly. Owing to the fuzziness about the driver's feeling, in this thesis, the calculation model of driver's feeling to safety speed is established by the methods of Fuzzy Interference System in Fuzzy Mathematics.From the angle of the traffic system about "man-vehicle-road", this thesis analyzes and selects the main factors that affect the driver's feeling about safety speed. Through the measurement experiment to the first and third-rated road of the West nation highway and the third-rated road between Chang (an) and Zi (wu), the thesis establishes the database of line type, road, transportation environment construction and three kinds of vehicles speed. Through the drivers' evaluation experiment, the thesis obtains the fuzzy data of road index and the vehicles' speed. Through analysis and handled with these data, the thesis abstains the research about driver's feeling to safety speed with fuzzy model. To visualize the result, the research is verified on the platform of Windows XP utilizing GUI of the fuzzy logic toolbox in MATLAB 5.3,and has a concrete example 210-nation highway calculation. |
