Decision support system of supervision and emergency for network operation in urban rail transit

This paper proposed approach of integrating supervision alarms and trains located on the map to support emergency management of urban rail transit network. The characteristics of dynamic passenger flow are analyzed to figure out transfer coordination and evacuation schema, related algorithm is developed. Information sharing is discussed and method of connection timetable optimization for metro and other traffic tools are introduced in hub. Explored technologies are applied in supervision and emergency of decision support system, with introducing hierarchical structure for data exchange and applications. Implementation of the technical system shows its effectiveness in emergency treatment and rescue resource collocation in time.
