Synthetically considering these characteristics, the method of freeway management and control are presented according to four aspects: system objective orientation and concept design, system demand and requirement analysis, system data management and network structure, traffic control and accident detecting theory as well as its application. Function and structure of system are delimitated from the point view of integration. Construction and function demand of subsystem are analyzed and basic implement projects are presented. In this thesis, system data flow and management method and target which based on system network topology structure and equipment demand are described. Traffic modeling ideology and the process of making dynamic model as well as accident detecting program are presented with centralized and distributed traffic control theory in detail, then freeway ramp control theory which based on predictive model and its theoretic pattern are explored. Finally, based on the object oriented programming, program of accident detecting and checking on freeway is developed by using visual C++ as tool.
