摘要: 为了减少大型车辆内轮差引发的交通事故，从大型车辆内轮差事故特征入手，分析其事故车型、事故死亡率、事故空间特征及时间分布特征，进而对大型车辆不同交叉口右转时的内轮差形成机制进行分析。通过对大型车辆转弯情况调研，得出驾驶人转动方向盘随车辆轴距与交叉口长宽比的拟合函数，建立更趋向于实际的车辆转弯理论模型。分析获取的大型车辆右转内轮差模型，从人、车等方面提出更适宜的内轮差事故安全对策。
Abstract: In order to reduce the traffic accidents caused by the inner wheel difference of large vehicles, starting from the characteristics of the large vehicle inner wheel difference accidents, the accident models, accident mortality, accident spatial characteristics and time distribution characteristics are analyzed, and then the characteristics of the large vehicles turning right at different intersections were analyzed. By investigating the turning situation of large vehicles, the fitting function of the driver turning the steering wheel with the wheelbase of the vehicle and the aspect ratio of the intersection is obtained, and a theoretical model of vehicle turning that tends to be more realistic is established. Analyze the acquired right-turn inner wheel difference model of large vehicles, and propose more suitable safety countermeasures for inner wheel difference accidents from the aspects of people and vehicles.
