自动驾驶汽车（AV）可能作为一种道路运输技术在世界各地广泛传播。然而，成功采用自动驾驶汽车的两个条件是，它们必须同步共享，以避免对交通网络和环境造成负面影响，并且公众对该技术的接受程度必须很高。这两个条件的含义是，旅行者必须接受与不熟悉的其他人共享共享自动驾驶车辆（SAV）。被认为对接受有积极影响的两个因素是舒适和信任。本文对现实世界中全自动共享车辆的乘坐体验的特定属性如何影响舒适度和信任度评级进行了新颖的研究。为此，55 名参与者在测试设施的实验条件下体验了 SAV 穿梭车的乘坐体验。每次实验都涉及两名不相关的参与者，由一名安全操作员和一名研究人员陪同，在 SAV 中进行四次旅行，在此期间，为“面部方向”（向前/向后）和“最大车辆速度”（8/16 km/h）这两个自变量提出两个条件。参与者之间的演示顺序有所不同。每次运行后，参与者对因变量“信任”和“舒适”进行评分（后者由六个舒适因素组成）。在实验前的指导和汇报会议期间还获得了预期和评估评级。在信任和每个自变量之间发现了统计上显着的关系 (p < .001)，但在感知舒适度的情况下，这两个变量都没有关系。舒适度和信任度之间存在很强的相关性，这表明对 SAV 的信任度是感知舒适度的重要预测指标。这两个变量的实验前和实验后评分均显示出统计上显着的增加，特别是对于日常汽车驾驶员而言。
Autonomous Vehicles (AV) may become widely diffused as a road transport technology around the world. However, two conditions of successful adoption of AVs are that they must be synchronously shared, to avoid negative transport network and environmental consequences, and that high levels of public acceptance of the technology must exist. The implications of these two conditions are that travellers must accept sharing rides with unfamiliar others in Shared Autonomous Vehicles (SAV). Two factors that have been identified as being positive influencers of acceptance are comfort and trust. The present paper undertakes a novel examination as to how comfort and trust ratings are affected by specific attributes of the ride experience of travelling in a fully-automated real-world, shared vehicle. To this end, 55 participants experienced riding in an SAV shuttle under experimental conditions at a test facility. Each experimental run involved two unrelated participants, accompanied by a safety operative and a researcher, undertaking four trips in the SAV, during which two conditions were presented for each of the independent variables of 'direction of face' (forwards/backwards) and 'maximum vehicle speed' (8/16 km/h). Order of presentation was varied between pairs of participants. After each run, participants rated the dependent variables 'trust' and 'comfort' (the latter variable comprised by six comfort factors). Expected and evaluative ratings were also obtained during pre-experimental orientation and debriefing sessions. Statistically significant relationships (p < .001) were found between trust and each of the independent variables, but for neither variable in the case of perceived comfort. A strong correlation was found between comfort and trust, interpreted as indicating trust in the SAV as an important predictor of perceived comfort. The before and after-experiment ratings for both variables showed statistically significant increases, and particularly for daily car drivers.
