Research on Rapid Snow Removal Strategy on Seasonal Frozen Area Highway under Snowstorm Weather

Snowstorms bring negative influence to the traffic environment,and rapid removal of snow slip is an important measure to ensure the safety of drivers.With the analysis of fast division effect snow management unit,the management unit division logic model and rapid snow management unit recommended standard have been put forward.The proposed division of snowfall and corresponding treatment measures has been made based on snowfall,snow thickness and impact on traffic operation.And it establishes the rapid snow removal machine allocation model based on the analysis of select the snow machinery allocation on different snowfall conditions with fast reaction time limit for index.In the model,influence factors include the snowfall,management unit length and snow machinery efficiency,and it proposes a quick snow removal machine allocation recommendations.Finally,according to the division of management unit and rapid snow machinery allocation model,an implementation plan has been proposed for rapid removal of snow.It can provide technical reference for the seasonal frozen district highway and safety management of snow and ice in winter.
