The 20th and 21st joint COTA International Conference of Transportation Professionals (CICTP 2020-21)

In order to study the visual characteristics of prairie road drivers, urban roads were used as control group, and vehicle tests were carried out on prairie and urban roads respectively. K-means cluster analysis method was used to divide the fixation area characteristics of drivers. The distribution characteristics of drivers' fixation time were calculated and the goodness of fit test was carried out. Markov theory was used to solve the probability matrix and stationary distribution of driver visial transition, and the high frequency fixation area and visual transfer mode of prairie road were obtained. The results show that, compared with urban roads, the number of fixation areas of prairie road drivers is relatively less. The fixation time of prairie road drivers is generally long, which approximately subject to lognormal distribution. The probability of the driver to stay in the current fixation area is generally higher. Compared with the urban road, the driver pays more attention to the remote fixation area of the road. The research results can provide references for the safety design of prairie roads and the improvement of driving safety.
