摘要： 针对大型车辆右转内轮差引发的恶性事故问题，笔者利用数学建模的方法，通过对南京市公交车交叉口右转弯的实际情况进行调研，建立了3种逐步趋向于实际的理论模型。对3种理论模型进行分析计算，用不同函数表示内前轮和内后轮的行驶轨迹，进而得到公交车内轮差的3个禁停区域。以南京市某交叉口作为案例进行分析，给出3种模型禁停区域范围：①模型一、二、三禁停重合区域，即最宽处1.0 m月牙形区域为绝对禁止驶入的区域；②模型一、二重合区域，即最宽处1.7 m月牙形区域为相对危险的区域，在驶入时要严格注意转弯车辆状况；③模型三禁停区域，即最宽处2.5 m的月牙形区域为提高注意力区域，道路使用者应提高注意力，在有公交车转弯时也应严禁驶入该区域。研究结果可为交叉口施划出针对非机动车、行人的不同危险等级的禁停区域提供参考，以减少交叉口处公交车事故数量，提高公交车在交叉口的安全性、通过率以及道路交通设施的可靠性。

Abstract: Aiming at the malignant accidents caused by the difference in the inner wheels of large vehicles when turning right, mathematical modeling methods were used to investigate the actual situation of right-turning at bus intersections in Nanjing, and three theoretical models gradually tending to be more practical were established. The three theoretical models were analyzed and calculated, and different functions were used to express the trajectory of the inner front wheel and the inner rear wheel. And then the three no-stop areas of the inner wheel difference of the bus were obtained. Taking a certain intersection in Nanjing as a case study for analysis, the range of no-stop areas of three models is given: ①Model 1, 2 and 3 no-parking overlapping area, that is, the 1.0m crescent-shaped area at the widest point, is an absolutely prohibited area; ②Model 1 and 2 no-parking overlapping area, that is, the 1.7m crescent-shaped area at the widest point, is a relatively dangerous area. When driving in, close attention to the turning vehicle condition should be paid; ③Model 3 no-parking area, that is, the 2.5m crescent-shaped area at the widest point, is the place where road users should pay more attention and should not drive into the above area when there is a bus turning. The research results can provide a reference for the delineation of no-parking areas for non-motorized vehicles and pedestrians at intersections with different risk levels, so as to reduce the number of bus accidents at intersections and improve the safety and passing rate of buses at intersections and the reliability of road traffic facilities.

Key words: traffic engineering; internal wheel deviation effect; no-stop zone; bus; intersection
