The invention relates to a high-expressway vehicle following behavior quantification method considering a visual angle of a driver. The invention relates to the high-expressway vehicle following behavior quantification method considering the visual angle of the driver. The objective of the invention is to solve the problem that an existing vehicle following behavior quantification method is low in accuracy for the operation characteristics of vehicles on multi-lane roads in China. The method comprises the following steps: S1, acquiring vehicle running track data; s2, car-following fragment samples are screened out according to the step S1, the car-following fragment samples are classified according to the traffic scene where the vehicle is located, and a vehicle running track data set of all kinds of car-following fragment samples is obtained; s3, calculating a relative motion parameter between the following vehicle and the associated vehicle in the vehicle moving trajectory data set of each type of following fragment sample, and a parameter reflecting a view angle of a driver of the following vehicle; and S4, establishing an improved multi-lane FVD car-following model under various traffic scenes, and calibrating parameters of the car-following model by using a genetic algorithm. The invention belongs to the field of traffic engineering.

    一种考虑驾驶人视角的高快速路车辆跟驰行为量化方法,本发明涉及考虑驾驶人视角的高快速路车辆跟驰行为量化方法。本发明的目的是为了解决针对我国多车道道路车辆的运行特性,现有车辆跟驰行为量化方法准确性低的问题。过程为:S1、获取车辆运行轨迹数据;S2、根据S1筛选出跟驰片段样本,并根据车辆所处的交通场景对跟驰片段样本进行分类,得到各类跟驰片段样本的车辆运行轨迹数据集;S3、计算各类跟驰片段样本的车辆运行轨迹数据集中跟驰车辆与关联车辆间的相对运动参数,以及反映跟驰车辆驾驶人视角的参数;S4、建立各类交通场景下的改进多车道FVD跟驰模型,并使用遗传算法标定跟驰模型参数。本发明属于交通工程领域。
