摘要
为探究高速公路养护工程安全变道概率条件下车辆行驶的控制距离,对变道过程中车辆跟驰行驶安全约束条件进行分析,并运用概率论与交通流理论研究车辆变道概率组合特性,推导出安全变道控制距离与成功变道概率之间的关系.结合实例计算,对推导模型与规范中的建议值和计算值进行吻合性验证.
Abstract
In order to explore the control distance of vehicle driving under the condition of safe lane change probability in expressway maintenance engineering,the safety constraints of vehicle following during lane change are analyzed,and the combination characteristics of vehicle lane change probability are studied by using the probability theory and the traffic flow theory.The relationship between the control distance of safe lane change and the probability of successful lane change is derived.Combined with the calculation of an example,the consistency between the derived model and the recommended and calculated values in the specification is verified.
