The friction coefficient (FC) will be reduced when the roads is covered by ice-snow, and the traffic operation risk will be increased in the regions(as Harbin Heilongjiang province in China) with high latitudes, whose winter is long and cold , and those conditions led to the reduction of road capacity and the increase of traffic delays. Using the video detection device, one of the traffic flow information collecting devices, a large number of data in the period of ice-snow of cold area are collected, which is the research base of this paper. The macro and micro traffic flow characteristic of urban road under ice-snow conditions is analyzed, such as the traffic flow, the distribution of headway time, and the properties of the speed distribution. The relation models of FC of ice-snow road and speed-volume are built. Then, the traffic flow characteristics are compared between ice-snow and non- ice-snow road. The outcomes studied above are the foundation for analyzing traffic operation and capacity of urban road in the period of ice-snow.
