摘要 隧道入口空间环境的剧烈变化会导致事故频发且级别较高。互联车辆环境为驾驶员提供周围交通信息，并通过帮助他们高效地做出安全决策来改善他们的驾驶行为。因此，本研究旨在研究联网车辆环境对隧道入口区驾驶行为和安全的影响。为此，本研究模拟联网车辆环境，并通过人机界面（HMI）提供驾驶辅助。其次，40名不同背景的参与者在两种不同的驾驶条件下驾驶模拟器：HMI-OFF（传统驾驶环境）和HMI-ON（联网车辆环境）。最后，从速度控制性、稳定性和紧迫性中选取指标，分析车联网环境对警戒区和隧道入口区驾驶员行为和安全的影响。结果表明，在车联网环境下，驾驶员在警戒区内的速度控制能力得到改善，减速行为也得到改善。隧道入口前方100m处，驾驶员的速度控制能力和稳定性得到提高，事故危险程度降低。此外，在隧道入口后300m处，驾驶员的速度控制能力和稳定性均得到改善。总体而言，在车联网环境下，驾驶员可以提前识别隧道并及时调整行驶速度，确保隧道入口的安全。这项研究的结果对于联网车辆环境中预警系统的设计和研究发挥着至关重要的作用，也将指导汽车制造商设计自动驾驶汽车的安全相关功能。本研究构建了基于驾驶仿真技术的车联网环境测试平台，并在特定隧道入口场景进行测试，为实现隧道入口车辆的主动防护提供参考。
Abstract The drastic changes of the space environment at the tunnel entrance can lead to frequent accidents with higher levels. The connected vehicle environment provides drivers with surrounding traffic information and improve their driving behavior by helping them make safe decisions efficiently. As such, this study is to examine the effects of the connected vehicle environment on driving behavior and safety at the tunnel entrance zone. To this end, this research simulates a connected vehicle environment and provides driving aids through the Human-Machine Interface (HMI). Secondly, 40 participants with diverse backgrounds drove the simulator under two different driving conditions: HMI-OFF (traditional driving environment) and HMI-ON (connected vehicle environment). Finally, indicators are selected from speed control, stability and urgency to analyze the impact of the connected vehicle environment on drivers’ behaviors and safety at the warning zone and tunnel entrance zone. The results show that in the connected vehicle environment, the drivers’ speed control in the warning zone is improved and their deceleration behavior is advanced. The driver's speed control and stability are improved while the danger level of the accident is reduced 100 m ahead of the tunnel entrance. Besides, the driver's speed control and stability have been both improved 300 m after the tunnel entrance. Overall, in the connected vehicle environment, the driver can recognize the tunnel in advance and adjust his driving speed in time to ensure his safety at the tunnel entrance. The results of this study play a critical role in the design and research of warning systems in a connected vehicle environment, and will also guide vehicle manufacturers in designing safety-related functions of automated vehicles. In this research, a connected vehicle environment test platform based on driving simulation technology is constructed and tested in specific tunnel entrance scenarios, which provides a reference for realizing active protection of vehicles at the tunnel entrance.
