Changing Rule of Driver's Recognition Distance in Daytime and Nighttime on Freeway

摘要

摘要: 为了制定高速公路昼夜车速限制标准,保障高速公路驾驶员有足够的时间获取信息,采用数理统计与回归分析方法,对采集的驾驶员昼夜识别距离数据进行了对比分析,研究了行驶速度、平曲线半径和公路纵坡对高速公路驾驶员昼夜识别距离的量化影响,建立了驾驶员昼夜识别距离与行驶速度、平曲线半径、公路纵坡的多元关系模型.研究结果表明,驾驶员夜间识别距离与白天相比平均下降8.5%,最大下降30.4%,下降幅度与行驶速度和公路线形条件有关;驾驶员白天识别距离与行驶速度、平曲线半径、公路纵坡分别呈负对数、正线性和负指数相关,模型的相关系数为0.852;驾驶员夜间识别距离与行驶速度、平曲线半径和公路纵坡分别呈负线性、正对数和负指数相关,模型的相关系数为0.983.

Abstract: In order to set the speed limit standard on freeway in daytime and nighttime and to ensure enough time for drivers to acquire information, the data of driver's recognition distance in daytime and nighttime were compared and analyzed using mathematical statistics and regression analysis methods. By studying the quantitative impacts of driving speed, horizontal curve radius, and longitudinal slope on driver's recognition distance in daytime and nighttime, models were established for the relationship among driver's recognition distance, driving speed, horizontal curve radius, and longitudinal slope. The results show that the driver's recognition distance in nighttime decreases by 8.5% averagely and 30.4% maximally compared with that in daytime. The decreasing rate is affected by driving speed and highway alignment. The relationship between driver's recognition distance in daytime and driving speed, horizontal curve radius, and longitudinal slope are negative logarithmic, positive linear,and negative exponential, respectively; and model's R-square is 0.852. In contrast, the relationship between driver's recognition distance in nighttime and driving speed, horizontal curve radius, longitudinal slope are negative linear, positive logarithmic, and negative exponential, respectively; and model's R-square is 0.983.
