| 目的 针对行人与自动驾驶汽车的交互过程，从行人的角度出发，探索性地提出行人在自动驾驶汽车前的过街行为决策模型。方法 首先，将行人过街情景进行分析定义，针对行人的过街意向和与自动驾驶汽车沟通意愿总结出两个典型场景;然后，利用潜变量分析方法将行人在自动驾驶汽车前过街行为的影响因素进行降维分类，并对车外人机交互界面进行设计定义，构建各潜变量的影响因子与测量量表;最后，运用有序Logistic回归方法分析各影响因素对行人过街意向和沟通意愿的影响，构建行人在自动驾驶汽车前的过街行为决策模型。结果 量化分析行人过街行为影响因素与其过街决策间相关性及内在关系，提出过程中决定性人车交互方式及各影响因素的变化过程。结论 研究提出考虑eHMI的行人过街行为决策模型，将行人过街决策过程分为三个阶段，并总结出车辆行为线索和eHMI线索作用过程的决定性变化曲线及行人与自动驾驶汽车交互流程与关键性节点。 |

| Aiming at the interaction process between pedestrians and autonomous vehicles, the work aims to propose an exploratory decision-making model of pedestrians crossing the road in front of autonomous vehicles from the perspective of pedestrians. Firstly, the pedestrian crossing scene was analyzed and defined. According to the pedestrian crossing intention and traffic intention, two typical pedestrian crossing scenes were summarized. Then, the influencing factors of pedestrians crossing the road in front of autonomous vehicles were classified by latent variable analysis. The external human-machine interface was designed, and the influencing factors and measurement scale were constructed. Finally, the orderly Logistic regression method was used to analyze the influencing factors of pedestrian crossing behavior on pedestrian crossing intention and traffic intention, and a decision-making model of pedestrian crossing the road in front of autonomous vehicles was constructed. The correlation and internal relationship between the influencing factors of pedestrian crossing behavior and their crossing decisions were analyzed quantitatively and the decisive interaction mode between pedestrians and vehicles and the changing process of each influencing factor in the process were put forward. A pedestrian crossing behavior decision-making model considering eHMI is proposed in this work, which divides the pedestrian crossing decision-making process into three stages, and summarizes the decisive change curve of vehicle behavior cues and eHMI cues, as well as the interaction process and key nodes between pedestrians and autonomous vehicles. |
