自动驾驶汽车外显界面对过街行人的行为影响研究

Research on the Influence of Autonomous Vehicle’s External Display Interface on the Behavior of Crossing Pedestrians

为探究自动驾驶汽车外显界面不同的呈现形式和角度对过街行人行为产生的影响,针对外显界面不同的呈现方式设计实验。对自动驾驶汽车外显界面有一个主观评价,并且将参试者在面对不同的外显界面呈现内容时过街的平均通过时间以及通过率作为客观指标进行分析。结果表明,在客观评价指标中以行人为中心用文字的呈现形式平均通过时间最低5.5s,在主观评价指标中以行人为中心用图文结合的呈现形式评分最高8.3分,得出结论:自动驾驶汽车外显界面以行人为中心用文字或者图文结合的呈现形式效果最优。

In order to explore the influence of different presentation forms and angles of the external display interface of autonomous vehicles on the behavior of pedestrians crossing the street, an experiment was designed for the different presentation methods of the external display interface. There is a subjective evaluation of the external display interface of the self-driving car, And the average pass time and pass rate of the participants when they face different external display interfaces to present content as objective indicators are analyzed.The results show that the average passing time of the presentation form with pedestrians as the center in the objective evaluation index is 5.5 s, and the highest score is 8.3 points in the subjective evaluation index with the presentation of the pedestrian as the center and the combination of graphics and text,It is concluded that the display interface of self-driving cars with pedestrians as the center, using text or a combination of graphics and text, has the best effect.
