Abstract:

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.

Key words: engineering of communications and transportation system, snow-ice weather, regional traffic, traffic capacity, traffic status, real-time discrimination
