摘要
湖南省西部地区以山岭、重丘为主,地势起伏大,垂直小气候明显,一些长大纵坡路段的行车安全成为了交通管理的重点。为了分析雨雾气象对长大纵坡路段的行车影响,在对试验路段进行雨雾气象和交通环境方面监测的基础上,结合现场不同天气状况下的驾驶试验,通过采集路段地理信息采集、行车速度、驾驶员脉搏血氧饱和度、车辆三轴加速度等数据,从雨量大小、雾的等级两方面分析得到了其对行车速度、驾驶员心理、驾驶稳定性操作等方面的影响。
The western part of Hunan Province is dominated by mountains and heavy hills. The terrain is undulating and the vertical climate is obvious. The safety of driving on some long longitudinal slopes has become the focus of traffic management. In order to analyze the influence of rain and fog weather on the long longitudinal slope road section,we have monitoring the rain-fog weather and traffic environment information. Combined with the driving tests under different weather conditions on the scene,we have collected the data such as road section geographic information,driving speed,driver's pulse oxygen saturation,vehicle three-axis acceleration,etc.. Then the influence on driving speed,driver psychology,driving stability and other aspects was obtained from the analysis of rainfall size and fog level.
