Abstract: The definition of several delays and the relationship among different delays at signalized intersection were reviewed firstly.Secondly，the commonly used field investigation，simulation，theoretical analysis and other methods to obtain the signalized intersection delay were summarized.According to the theoretical analysis method，the Webster delay model was deduced in detail，and the classic models of the theoretical analysis method widely used in a long history were described，including HCM2000，Miller and Akcelik.Moreover，the characteristics of the above classic models in the parameter acquisition were analyzed.By use of the principle of point sample method，the application of video method in delay acquisition was introduced.Finally，the field investigation，simulation method and theoretical analysis method to obtain the delay method were reviewed and discussed.Combined with the current research，the development trend of the acquisition of delay parameters was also analyzed，
