Research And Realization Of Fuzzy Logic Based Automatic Freeway Incident Detection And Speed Control System

Some researches of Freeway Supervisory Control System are introduced in this thesis. The main contents are as follows:Firstly, A Fuzzy Pattern Recognition based Automatic Freeway Incident Detection Algorithm is given. This algorithm solves the problem that the density of the Vehicle Detectors distribution is too low to apply traditional AID algorithms.Secondly, A Fuzzy Logic based Variable Speed Control method is given. This method slides over the difficulty of accurately traffic flow modeling in practical project.At last, the design and realization of Freeway Supervisory Control System software is presented. In this part, the key technology such as Device Object Abstraction, Communication Scheduling and Control Algorithms Encapsulation is introduced.
