    摘要:

    大型地下停车场内部通道窄、视野受限导致盲区交叉口会车容易发生碰撞,危险性较高。文章通过搭建地下停车场3D模型和网联信息预警系统设计驾驶模拟实验,分析地下停车场盲区交叉口抵近行为。考虑技术水平和盲区冲突设计4种实验场景,基于31名被试的微观驾驶行为数据,选取平均速度、平均加速度、制动位置分析预警点到盲区交叉口范围内的驾驶行为。在相关性分析的基础上运用k-means方法选择初始速度、平均速度对驾驶员类型进行聚类,分析网联预警信息对不同驾驶员抵近行为的影响。研究结果表明:1)驾驶员在无预警信息提示时抵近盲区交叉口的过程包括速度保持——速度增加——速度急减三个阶段,在有预警时速度均匀下降,通过交叉口时的速度较无预警时高34.08%;2)预警信息使得驾驶员平均速度较无预警场景降低9.94 km/h,制动位置提前4.49m,有效提升驾驶员在停车场盲区交叉口的安全性;3)预警系统对保守型和普通型驾驶员作用效果明显,对于激进型驾驶员应当进行必要的培训,使其认识到预警系统的积极作用,以提高行车效率、促进安全驾驶。研究结果对网联信息预警系统在停车场的应用和停车场安全性提升提供支撑。

    Abstract:

    The narrow passage and limited vision in the large underground parking lot lead to the collision of vehicles at the blind intersection, which is very dangerous. This paper designs a driving simulation experiment by building a 3D model of the underground parking lot and a connected vehicle warning information system to analyze the approach behavior of the blind intersection of the underground parking lot. Four experimental scenarios were designed considering the technical level (with or without information warning) and events (with or without vehicle conflict at blind intersection). Based on the micro-driving behaviors of 31 subjects, speed, acceleration and braking position were selected to analyze the approach behaviors from the warning point to the blind intersection. Two indexes of initial speed and average speed were selected, and k-means method was used to cluster driver types, and the influence of connected vehicle warning information on different drivers" approach behavior was analyzed. The results show that: 1) When the driver approaches the blind intersection without warning information, the process includes three stages: speed maintenance, speed increase and speed decrease. When there is warning information, the speed decreases evenly, and the speed through the intersection is 34.08% higher than that without warning information. 2) The warning information reduces the average speed of drivers by 9.94km /h compared with the scenario without warning, and advances the braking position by 4.49m, effectively improving the safety of drivers at blind intersections in parking lots. However, the warning information can not make the three types of drivers" behavior consistent. The average speed of aggressive drivers is still higher than that of conservative and general drivers, and the braking position is closer to the blind intersection. 3) The early warning system has obvious effects on conservative and general drivers, and necessary training should be given to radical drivers to make them realize the positive role of the warning system, so as to improve driving efficiency and promote safe driving. The research results provide support for the application of connected vehicle warning information system in parking lot and the improvement of parking lot safety.
