With the rapid development of urban expressway, the ramp congestion of expressway is frequent, and the ramp control of expressway exit has been widely concerned. There have been more research and application on the control of expressway exit in China, and the control mode is mainly focused on the adjustment of the adjacent auxiliary road intersection on the ramp. In order to continue to find ways to solve the problem of congestion on exportation of expressways, and provide reference for the research of expressway exit control, the existing control methods are summarized. Although most of the exportation control is adopted to adjust the signal of the auxiliary road at present, the object of the control is not the same. Therefore, the object different according to the control means can be divided into three kinds: the priority of the ramp, the dynamic adjustment of the auxiliary road and the cooperative control of the multi system. This article will summarize and analyze the existing research results, and put forward some views on the future research and development.
