Emergency situations on the road network and need of them treatment under the Intelligent Transport System to allow adaptive traffic control are considered. Described a representation of the road network as a directed weighted graph, where weight of edge is probabilities of vehicle travel throw the edge. Characteristics of emergency situations are detected – type, zone of direct influence, time of appearance and disappearance, expectation value of emergency situation existence period. Classification of emergency situations by different features was made. By the spatial arrangement emergency situations are divided into dot emergency situations, linear emergency situations and areal emergency situations. By the source of appearance emergency situations are divided into emergency situations, caused by environment, by road network, by technical means of traffic management and by traffic.
