The purpose of the study is to build a model of the influence of weather and climatic factors on the throughput of various types of roads and intersections. Weather conditions affect the acceleration, braking and stability of a vehicle on the road. The results show that the weather affects traffic intersections of streets, which need to be optimized depending on the current road and transport situation. As a result, a model of the influence of rain, snow and ice on road situations was simulated and built.
