| Abstract: | According to reduction of visibility and adhesion,the paper researches safe driving speed on freeway at the rain.Proceed from stop process under the following state,in response to obtained corresponding adhession coefficient from different rain water depth,it calculates also safe driving speed on freeway,based on the AASHTO model of stop apparent distance.Finally the measures for traffic control at the rain have been gotten,which may provide reference for tecnicians. |
