摘　　要：驾驶行为的产生是驾驶员通过对行车环境的感知、判断和决策,通过操控车辆运行形成的,它受到众多因素的影响,其中行车环境自然是主要的方面。通过对大量农村公路条件下的实车驾驶数据进行分析,探究在农村公路行车环境下车辆速度、三轴加速度等运行特征变化的规律,旨在探究行车环境与驾驶行为的相互关系,为提高农村公路行车环境的协调性提供技术参考。Driving behaviors generate when the driver is perceiving the driving environment,making judgment and decision,then manipulating the vehicle.It is influenced by many factors and driving environment is one of the most important aspects.Through analyzing a large number of data under real vehicle experiments on rural roads,the change rule of vehicle characteristics such as vehicle speed and the triaxial acceleration in different driving conditions was explored.It aims to discuss the relationship between the driving environment and driving behavior and provide some suggestions for the research of rural highway traffic environment coordination.
