This research is aimed at investigating drivers’ attitudes towards connected vehicle technology in general and two connected vehicle applications in particular—Lane Speed Monitoring and High Speed Differential Warning—which have been demonstrated via simulation to be effective in enhancing traffic mobility and safety, respectively. An online survey was sent to customers of an automobile manufacturer in the United States. Out of the 1453 survey responses that were received, 650 complete and valid responses were used to analyze the respondents’ stated acceptance of and expected behavioral responses to the two connected vehicle applications under a variety of scenarios. Statistical analyses were conducted to examine the influence of demographic and socioeconomic factors. The results reveal that the respondents express high willingness to use connected vehicle technology and the two applications under various circumstances, and the willingness is strongly associated with age, gender, education level, and income. Higher levels of acceptance are observed in older, male, higher-educated, or higher-income respondents, while the patterns of conditional acceptance and expected behavioral responses vary with specific scenarios. These results provide useful information for application developers, traffic operators, and policy makers to steer connected vehicle technology development and deployment in the direction that will benefit both the users and the society.

这项研究的目的是调查驾驶员对总体上联网汽车技术的态度，尤其是对两种联网汽车应用（车道速度监控和高速差速警告）的态度，通过仿真已分别证明了它们有效地提高了交通机动性和安全性。在线调查已发送给美国一家汽车制造商的客户。在收到的1453份调查答复中，使用650份完整有效的答复来分析受访者在各种情况下对两种连接的车辆应用的接受和预期的行为回应。进行了统计分析，以检验人口和社会经济因素的影响。结果表明，受访者表示愿意在各种情况下使用联网汽车技术和这两种应用程序，并且这种意愿与年龄，性别，教育程度和收入密切相关。在年龄较大，男性，文化程度较高或收入较高的受访者中观察到接受程度较高，而条件接受和预期行为反应的模式随特定情况而异。这些结果为应用程序开发人员，交通运营商和政策制定者提供有用的信息，以指导互联车辆技术的开发和部署，从而使用户和社会都受益。在年龄较大，男性，文化程度较高或收入较高的受访者中观察到接受程度较高，而条件接受和预期行为反应的模式随特定情况而异。这些结果为应用程序开发人员，交通运营商和政策制定者提供有用的信息，以指导互联车辆技术的开发和部署，从而使用户和社会都受益。在年龄较大，男性，文化程度较高或收入较高的受访者中观察到接受程度较高，而条件接受和预期行为反应的模式随特定情况而异。这些结果为应用程序开发人员，交通运营商和政策制定者提供有用的信息，以指导互联车辆技术的开发和部署，从而使用户和社会都受益。
