冰雪天气下的区域交通状态实时判别

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。

Real-time discrimination of regional traffic status under snow-ice weather

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.
