With the continuous development of social economy, traffic safety problems become increasingly prominent. Some cold regions have affected by snow and ice conditions for a long time, accident rate and accident severity increased significantly. Traffic safety problems are particularly serious. So the study of driving behavior in cold regions is an important task for researchers and transportation management authorities. This paper analyzed the influence of snow and ice conditions on freeway traffic, which including drivers, vehicles and road conditions. The traffic operation video data under the normal conditions, as well as under ice and snow conditions, were collected and the driver's lane changing behaviors were analyzed. From the definition of the lane changing process, the distinction of the types, the influencing factors and the kinematics analysis, this paper analyzed the whole lane changing behavior, and explored the specific characteristics of the lane changing frequency. Based on video data can be found that driver's land changing behavior occurs frequently on the freeway, while the frequency of lane changing under snow and ice conditions is significantly higher than that in normal weather, and the proportion of forced lane changing increases, which brings great security risks. This study can be useful for the analysis of the causes of frequent traffic accidents, and play an important role in improving traffic operation efficiency and reducing accidents in cold region.
