Abstract: In order to ease traffic congestion effectively and improve road capacity fully,deep and comprehensive study on setting reversible lane was carried out. Firstly, the conditions of reversible lane were researched systematically. Then, contents setting of reversible lane scheme were analyzed. Based on the demand of contents, the setting principles were analyzed. In order to get a scientific and rational reversible lane setting scheme, the factors and corresponding indicators were analyzed clearly. The study can be directly used to guide the reversible lane settings.
