Design And Implementation Of Fuzhou 120 Emergency System Based On ITS

With the rapid development of social economy and the gradual improvement of social health care Business, the emergency work of the 120 which as the emergency medical service.is.also.increasingly need to support from network and geographic information technology. The traditional way of 120 working is voice communication between those who need help and the emergency center of 120, the staff of 120 command center judge and make decision for implementation for 120 emergency work according to the position of the one's who need help, this mode is low efficiency and lack of scientific in a some cases.This paper summarized and researched the latest development results of 120 emergency system of scholars at home and abroad, proposed the idea of integrating closely the intelligent Transportation (ITS) theory, the Fuzhou road transport network and "3G" technology based on a distributed spatial database to establish transportation network data model, and designed and developed 120 emergency WebGIS system that web-based service. The optimized Dijkstra algorithm is used as the core algorithm for the calculation of the system, which is used to calculate the best "two-path" path and the specific route and method from the accident to the emergency hospital, "two-path" shall be to the path of the rescue and return.
