Abstract: The characteristics of mixing traffic of vehicle, bicycle and pedestrian make intersections an accident-prone area. The study of drivers gaze behavior is an important way to guide drivers to turn right safely and reduce conflicts. Based on the psychological test of driving tendency, the questionnaire data of 109 drivers were collected and drivers were classified into radical type and cautious type. Six different types of drivers were selected to carry out eye movement experiment in real car, and the gaze behavior of drivers with different inclinations during right turn was studied. The research results show that: cautious drivers are composed mainly of women and people with higher driving experience, and radical drivers are composed mainly of people with lower driving experience and the ones who are about 30 years old. The drivers viewpoint path is linear in the right turn of the motor vehicle. Cautious drivers have higher fixation density and intensity than radical drivers when turning right. Radical drivers neglect the right side of the road when turning right, which results in more blind spots and dangerous spots in the conflict with pedestrians. The study provides a theoretical basis for solving the core issues of the conflict between right-turning vehicles and pedestrians, which trains the drivers visual search and risk awareness, improves drivers driving technology and reduces traffic accidents of right-turning vehicles and crossing pedestrians.

摘要： 机非混行的特征使交叉口是交通事故多发区域，驾驶员的注视行为研究是指导驾驶员安全右转、减少冲突的重要手段。依托驾驶员倾向性实验，采集了109 名驾驶员的问卷数据，将驾驶员分为保守型和激进型两类，并选择6名不同类别的驾驶员进行了实车眼动实验，对不同倾向驾驶员在右转过程中的注视行为进行研 究。研究结果表明：保守型驾驶员主要分布于大部分女性和高驾龄人群，激进型驾驶员主要分布于大部分驾龄较短和年龄在30岁左右的人群；机动车右转过程中 驾驶员视点路径呈线性分布，保守型驾驶员在右转时注视点密度和注视强度明显高于激进型驾驶员，激进型驾驶员在右转时忽视右侧区域，导致与行人冲突中存 在更多的盲区和危险点。研究为解决右转车辆与过街行人冲突的核心问题提供理论基础，训练驾驶人的视觉搜索和危险感知能力，提高驾驶员驾驶技术，减少机 动车右转与过街行人交通事故。
