本研究洞察了个体选择拥有和使用自动驾驶汽车的动机，并开发了自动驾驶汽车长期选择决策的模型。向居住在以色列和北美的721人分发了一份明确的偏好调查问卷。根据他们目前通勤的特点，向个人展示了不同的情景，并要求他们选择他们将使用的通勤汽车。一个包括三个选项的车辆选择模型被估计：(1)继续使用你拥有的普通汽车通勤。(2)购买并转向使用私人拥有的自动驾驶汽车(PAV)。(3)转向使用共享自动驾驶汽车(SAV)，从按需按需汽车车队。因子分析确定了描述个人态度的五个相关潜在变量：技术兴趣、环境关注、享受驾驶、公共交通态度和支持AV的情绪。通过包括Logit核模型在内的考虑面板效应的随机效用模型，量化了个体和自动驾驶汽车的特性对使用和接受的影响。目前，人们对自动驾驶汽车的采用总体上存在较大的犹豫，44%的选择决策仍然是常规车辆。早期的反病毒采用者可能是年轻、学生、受过更高教育、花更多时间在汽车上的人。即使SAV服务是完全免费的，目前也只有75%的人愿意使用SAV。研究还发现，以色列和北美在个人偏好上存在各种差异，即以色列人总体上更有可能转向自动驾驶汽车。鼓励使用无人驾驶汽车的方法包括增加普通汽车的成本，以及教育公众了解共享自动驾驶汽车的好处。(C)爱思唯尔有限公司发布的2017年。
This study gains insight into individual motivations for choosing to own and use autonomous vehicles and develops a model for autonomous vehicle long-term choice decisions. A stated preference questionnaire is distributed to 721 individuals living across Israel and North America. Based on the characteristics of their current commutes, individuals are presented with various scenarios and asked to choose the car they would use for their commute. A vehicle choice model which includes three options is estimated:(1) Continue to commute using a regular car that you have in your possession.(2) Buy and shift to commuting using a privately-owned autonomous vehicle (PAV).(3) Shift to using a shared-autonomous vehicle (SAV), from a fleet of on-demand cars for your commute.A factor analysis determined five relevant latent variables describing the individuals' attitudes: technology interest, environmental concern, enjoy driving, public transit attitude, and pro-AV sentiments. The effects that the characteristics of the individual and the autonomous vehicle have on use and acceptance are quantified through random utility models including logit kernel model taking into account panel effects.Currently, large overall hesitations towards autonomous vehicle adoption exist, with 44% of choice decisions remaining regular vehicles. Early AV adopters will likely be young, students, more educated, and spend more time in vehicles. Even if the SAV service were to be completely free, only 75% of individuals would currently be willing to use SAVs. The study also found various differences regarding the preferences of individuals in Israel and North America, namely that Israelis are overall more likely to shift to autonomous vehicles.Methods to encourage SAV use include increasing the costs for regular cars as well as educating the public about the benefits of shared autonomous vehicles.
