Global Traffic Model and Its Application for Accident Detection
Original language description
Automatic Incident Detection (AID) systems serve for recognition of traffic accidents in the data from particular part of road network. The input for such systems is continuously measured traffic parameters and the output can be utilized for traffic control systems and systems informing the drivers. This paper describes AID system based on global traffic state model created from historical traffic sensors data from a particular investigated area as a whole. The very high dimension of global multidimensional traffic states is reduced using Principal Component Analysis (PCA). Finally, the clustering methods are used in order to detect the abnormal states which most probably stand for accidental traffic conditions or other unwanted non-standard situations.
