摘要:

高速公路在雾天环境存在较大的驾驶安全风险和事故隐患,网联碰撞预警信息系统为解决该难题提供了新的思路,而其对驾驶行为的影响是论证其有效性的根本。该研究运用驾驶模拟技术搭建网联碰撞预警信息系统测试平台,考虑浓雾天气类型,设计基准传统和对照网联两种驾驶环境,构建前方慢速车辆急刹这一典型碰撞风险事件,招募27名被试开展驾驶模拟实验以获取细粒度微观驾驶行为数据。从稳定性、安全性、服从性多个维度构建评价指标体系,对网联碰撞预警信息系统在驾驶人与前车不同交互阶段(慢速跟驰、前车急刹)的效能展开了定量描述和统计分析。结果表明:在稳定性方面,碰撞预警信息会导致在慢速跟驰阶段的一段时间内驾驶稳定性降低,在慢速跟驰阶段车辆减速完成达到稳定状态之后和前车急刹阶段,其具有比无碰撞预警信息更好的稳定性;在安全性方面,碰撞预警信息使得驾驶过程中时间、加速度、距离多个层面的冲突风险均得到了显著减少;在服从性方面,碰撞预警信息能够提升驾驶人对于前车信息的服从水平,减弱驾驶人在慢速跟驰和前车急刹这两个阶段中对前车信息服从水平的差异性。研究成果可为高速公路雾天环境下网联碰撞预警信息系统的测试和应用提供平台支撑和理论支持。

Abstract:

Freeway driving in foggy conditions poses significant safety risks and accident hazards. The connected collision warning information system (CCWIS) offers a novel approach to addressing this challenge, and its impact on driving behavior is fundamental to demonstrating its effectiveness. This study employed driving simulation technology to create a CCWIS testing platform. Considering dense fog weather conditions, it designs two driving environments: a baseline traditional and a comparative connected. And a typical collision risk scenario involving a sudden braking maneuver by a slow-moving vehicle ahead was constructed. A total of 27 participants were recruited to conduct driving simulation experiments to yield fine-grained microscopic data on driving behavior. An evaluation indicator system was developed from multiple dimensions, including stability, safety, and compliance, to quantitatively describe and statistically analyze the effectiveness of CCWIS during different interaction stages with the lead vehicle (slow-speed car-following and the frout vehicle emergency braking stage). The results indicate that, regarding stability, collision warning information may lead to a decrease in driving stability for a period during the slow-speed car-following stage. After the vehicle in the slow-speed car-following stage has decelerated to a stable state and during the front vehicle emergency braking stage, it exhibits better stability compared to scenarios without collision warning information. In terms of safety, collision warning information significantly reduces risks in terms of time, acceleration, and distance across multiple dimensions during the driving process. Regarding compliance, collision warning information can improve the level of driver compliance with preceding vehicle information, reducing the differences in driver compliance with preceding vehicle information between the slow-speed car-following and the front vehicle emergency braking stages. The results of this study can provide platform and theoretical support for the test and application of connected collision warning information systems in foggy environments of freeways.
