高速公路旁廣告牌對(duì)駕駛安全的影響
[Abstract]:Objective: to explore the influence of different specifications, density and location of billboards on driving safety. Methods: the subjects with driving license were asked to drive the vehicle in the QJ-3B1 driving simulator and memorize the contents of the roadside billboard. The driving simulator recorded the indexes of operating the vehicle. The Smart Eye eye movement meter recorded the eye movement index during the course of watching the billboard. A total of four experiments, independent variables are: billboards of different specifications (large, medium, small), different density (none, low, high) and the different position of the bend (before, in, after the bend); The dependent variables were driving index (real-time speed, distance from car, lateral deviation) and eye movement data (total fixation times, total fixation time, longest gaze time). Each experiment was designed within 3 脳 2 subjects. Each experiment recruited 30 people who had obtained a driver's license. The task was to follow the car and pay attention to the billboards on the side of the road. Results: the results of experiment 1 showed that there was no significant difference (p0.05) in real-time speed and distance between car and car, while there was significant difference in lateral deviation and eye movement data (p0.05). Compared with the straight path, the lateral deviation of the curve is larger than that of the straight (p0.05), and the others are smaller than the straight (p0.05). The results of experiment 2 showed that there were significant differences in the following distance, lateral deviation, total fixation times and total fixation time between different concentration billboards when following the car (p0.05), whether it was curved or straight, the distance from the car, the lateral deviation, the total fixation times and the total fixation time (p0.05). There was no significant difference between real-time speed and maximum fixation time (p0.05). The results of experiment 3 showed that there were significant differences in driving behavior and eye movement behavior between different positions of billboards when following the car (p0.05). When the left and right bends were compared, the lateral offset, the total fixation time, and the longest fixation time were left bend greater than right bend (p0.05), while the others were left bend, and there was no significant difference between right bend and left bend (p0.05). The results of experiment 4 showed that there was no difference in the longest watching time (p0.05) except for the billboards (the billboards were on the left side of the road). All the other indexes were different (p0.05). The results of experiment 4 were as follows: (1) there was no significant difference between the two groups (p > 0.05). Compared with the left and right bends, the lateral offset of left bend was greater than that of right bend (p0.05), the total fixation times of left bend was smaller than that of right bend (p0.05), the others were left bend, and there was no difference between right bend and left bend (p0.05). Conclusion: the billboard on the side of highway has influence on driving safety, including: (1) the effect of billboard specification on driving behavior is influenced by road type, and the bend is larger than the straight road; Driver's eye movement behavior is affected by billboard specifications: large billboard gaze times, long time. (2) the effect of billboard intensity on driving behavior is influenced by road type. When bending, the billboard with high density has a large lateral offset, a small distance from the car, a large influence, a low concentration of billboards, a small lateral offset, a large distance from the car, and is relatively safe. When straight, when no billboard, the distance to the car is large, the lateral offset is small, the density is low and the height is not different. Different road types have an impact on driving behavior, and the bend has a greater impact. The real-time speed is less than straight, distance from car, lateral offset is larger than straight. (3) whether the billboard is on the right side of the road or on the left side of the road, the influence of the right corner is less; The middle position of the bend has the greatest influence on the driving safety, and the position in front of the bend has the least effect on the driving safety.
