摘要
为研究多车道高速公路出口车辆换道行为,提出了出口换道车辆样本的识别指标与标准。基于筛选出的高速公路出口段的车辆换道样本,分析了不同换道需求次数下的出口换道位置分布特征,确定车辆换道影响范围,通过对车辆换道影响范围图的特征和原因的分析,并结合实际情况,提出高速公路出口诱导设置的建议。基于最后一次换道和路段上普通换道的持续时间、速度、横向加速度、纵向加速度样本,利用SPSS中T检验模块,完成换道过程中的车辆运动状态特征显著性分析。最后,找出换道意图关键影响因素,构建驾驶人换道意图与各关键影响因素的二元Logistic关系模型。
The objective of this paper is to study the lane changing behaviors in the range of the highway exit. The paper explores the identification index and the standard of the export lane changing vehicle sample. Based on the selected lane changing sample in the range of the highway exit,the paper studied the dynamic characteristics of lane changing and the factors affecting the lane changing. With the analysis of the distribution characteristics of lane changing location during the range of the highway exit, the paper studies the reach of lane changing. With the reach of lane changing, the paper purposed several traffic management suggestions for the position of the signs in the range of a highway exit ramp. Then, it studies the distribution characteristics of lane changing duration. The effect of factors such as the velocity, the lateral acceleration, the longitudinal acceleration and the reach of lane changing in the two independent sample of the last time lane changing and the common lane changing are determined. It completes the significant analysis of the above data in the two independent sample through T examination. The binary logistic relationship model between drivers' lane changing intention and the key factors is established by determining the characteristic indexes of drivers' lane changing intention.
