Since Intelligent Transport Systems(ITS) is a complex project combining technology and system of transportation, information and communication and civil engineer, it needs a specialized management activities. However, it is difficult to judge who has responsibility for a shoddy and fault construction since the role between project management and supervision is very ambiguous. The aim of this study is propose an efficient project management and supervision for ITS reflecting the characteristics of ITS. Therefore, we suggest a statistical models using nonlinear regression model to prepare the project management and supervision compensation criteria, hence, we choose the realistic and validation statistical model.
