摘　　要：在研究现有常态天气下交通状态判别的基础上,充分考虑冰雪灾害对道路通行能力的影响,提出了适用于冰雪天气条件下的路段和交叉口的交通状态判别方法。同时考虑道路的等级、路段的通行能力以及路段长度等因素,确定了路段和交叉口的交通状态权重,实现了区域交通状态实时判别。最后利用TransModeler微观仿真软件对本文方法进行了验证。结果表明:该方法判别准确度较高、判别时间较短,为冰雪条件下交通状态研究提供了新的思路。On the basis of existing traffic status discrimination under normal conditions, considering the influence of snow-ice disaster on road capacity, real-time discrimination methods of section and intersection under snow-ice weather was proposed. Through considering factor such as road level, section capacity and section length, determined traffic status weights of sections and intersections, achieved the real-time discrimination of regional traffic status. The method was verified using TransModeler microscopic simulation software. The results showed that under snow-ice weather the method has good performance in aspects of accuracy and prediction time, it provides new ideas for traffic state discrimination field under snow-ice conditions.
