摘要
为研究不同经验驾驶员稳定跟车状态下的驾驶特征,选取累计驾驶里程作为驾驶经验衡量标准。在特定的交通环境下,利用车载激光雷达设备,对比分析有无驾驶经验稳定跟车状态下的跟车距离和车头时距的特征,并建立相应的分布函数,揭示不同驾驶经验条件下稳定跟车行为的差异表现。研究结果表明:稳定跟车状态下,无经验驾驶员的跟车距离普遍比有经验驾驶员高,驾驶员的累计驾驶里程与跟车距离有显著的相关性,相关系数为负值,无经验和有经验驾驶员的跟车距离均服从对数正态分布;无经验驾驶员的车头时距也普遍比有经验驾驶员高,驾驶员的累计驾驶里程与车头时距有显著的相关性,相关系数亦为负值,无经验和有经验驾驶员的车头时距均服从正态分布。
To study the driving characteristics of drivers with different driving experiences in a stable follow up, this paper chooses the cumulative driving distance as the driver＇s driving experience measurement standard, using the vehicle mounted laser radar equipment in a specific traffic environment. The characteristics of follow up distance and headway distance under the state of driving experience steadily are compared and analyzed and established. The corresponding distribution function reveals the difference in the behavior of stable follow up behavior under different driving experience conditions. The research result shows that the inexperienced driver＇s follow up distance is generally higher than that of the experienced driver in the stable follow up state. The driver＇s cumulative driving mileage and follow up distance have a significant correlation： the correlation coefficient is negative, and the follow up distances between inexperienced and experienced drivers obey the lognormal distributions. Inexperienced drivers - headway is also generally higher than that of experienced drivers. There is a significant correlation between the driver＇s cumulative driving distance and headway： the correlation coefficient is also negative, the headways of inexperienced and experienced drivers both obey normal distributions.
