Limited visibility in tunnels delays accident detection, and the impact of a collision can rapidly escalate throughout the tunnel. This limited visibility highlights the importance of maintaining smooth vehicle interactions through enhanced situational awareness within the tunnel. The difficulties with situational awareness in tunnels can be overcome by lighting the tunnel or providing traffic information in advance to improve perception. Being aware of the situation ahead is particularly beneficial to the driver. This paper uses a multi-agent driving simulator to analyze the impact of information delivery through variable message signs (VMS) and head-up displays (HUD) on drivers and how this effect changes based on lighting intensity and speed limits. The study involved 32 experimental participants who wore VR-HMDs, performed five scenarios and took a post-survey. Statistical comparisons and analysis of changes in driver behavior under each scenario were performed. The results showed that the information delivery system improves the driving safety of the vehicle. In particular, the HUD was affected by the lighting intensity and speed limits. Regarding safety, drivers aware of the information in the tunnel in advance had a 51.29% reduction in reaction time for the vehicle in front of them. The impact of this information delivery system increased at lower speed limits; however, for the HUD, this impact diminished as the lighting intensity decreased. Therefore, delivering traffic information to drivers in advance through a well-designed information system can promote safer driving behavior upon entering a tunnel.

隧道中信息传递系统对照明强度和速度限制的影响
隧道中的能见度有限会延迟事故检测,并且碰撞的影响会迅速升级整个隧道。这种有限的能见度凸显了通过增强隧道内的态势感知来保持平稳车辆交互的重要性。隧道中态势感知的困难可以通过为隧道照明或提前提供交通信息来提高感知能力来克服。了解前方的情况对驾驶员特别有益。本文使用多智能体驾驶模拟器来分析通过可变消息标志 (VMS) 和平视显示器 (HUD) 传递信息对驾驶员的影响,以及这种影响如何根据照明强度和速度限制而变化。该研究涉及 32 名佩戴 VR-HMD 的实验参与者,他们执行了 5 个场景并进行了事后调查。对每种情况下驾驶员行为的变化进行了统计比较和分析。结果表明,信息传递系统提高了车辆的驾驶安全性。特别是,HUD 受到照明强度和速度限制的影响。在安全性方面,驾驶员提前了解隧道中的信息,前方车辆的反应时间缩短了 51.29%。这种信息传递系统的影响在较低的速度限制下增加;但是,对于 HUD,这种影响会随着照明强度的降低而减弱。因此,通过精心设计的信息系统提前向驾驶员提供交通信息,可以促进进入隧道时更安全的驾驶行为。
