Abstract

In order to provide driver the basis experiment data and the evaluation subordination functions that are needed in speed-controlling model, the driver thinking evaluation procedure and safety perception to road structure and traffic environment were studied by fuzzy set principle and fuzzy statistic experiment analysis method. The road structure parameters of 226 highway sections were obtained from typical second-class highway sections of national roads, 1 785 groups of driver effective perception data of 131 highway sections were obtained from specialists' appraising experiment, the nonzero-sets of perceived comment collection based on 0. 2-cut sets and the certain-sets based on 0. 8-cut sets were set up, the simulation model and fuzzy comment subsets of driver safety perception to second-class highway structure and traffic environment were put forward.
