A method for selecting an emergency vehicle evacuation route

Abstract

The invention discloses an ambulance evacuation path selection method. The method includes the following steps: S001, acquiring GIS (geographic information system) geographic information, road network information and realtime traffic data; S002, setting an initial value of a variable (i)i( / i) to be 1; S003, calculating shortest running time of an ambulance from a patient position to the (i)i( / i)th emergency center; S004, calculating average waiting time after a patient is carried to the (i)i( / i)th emergency center; S005, increasing (i)i( / i) by 1, repeating S003 and S004 until traversing all emergency centers; S006, selecting an emergency center with a minimum sum of the shortest running time and the average waiting time as an optimal emergency center, and carrying the patient to the optimal emergency center by the ambulance according to a path corresponding to the shortest running time. By the ambulance evacuation path selection method, the problem that conventional ambulance path selection algorithms are useless to medical rescue and treatment is solved, and maximization of ambulance resource utilization rate is realized. The ambulance evacuation path selection method is suitable for circumstances that wounded personnel is large in number and emergency centers need coordinated dispatching.

Description

technical field [0001] The invention relates to the field of medical rescue, in particular to a method for selecting an evacuation route for an ambulance when a relatively large-scale accident occurs and there are many wounded. Background technique [0002] As my country's urbanization continues to increase and the urban population continues to increase, medical services, especially emergency medical services, are increasingly challenged. In the emergency medical service, the ambulance is an important carrier of the emergency medical service, and it undertakes the function of transporting medical personnel to the scene and transporting the patient to a suitable emergency center. The complex traffic conditions in cities, especially in large cities, and the increasing congestion of emergency rooms have put forward higher requirements for the route selection of ambulances. [0003] The existing technical methods are all concerned with the algorithm research on how to transfer ...

Problems solved by technology

However, this scheme still only considers the coordinated control between a single point and a single point. When there are many wounded and need to be sent to different emergency centers, appropriate deployment arrangements cannot be made.
