Research on the emergency response system of major dangerous chemical accident on highway based on the GIS

摘要

In order to improve the efficiency of emergent response of major dangerous chemical accident on the highway, the emergency response system of major dangerous chemical accident on highway based on the GIS is researched and developed. Due to the characteristic of the emergent response of major dangerous chemical accident on the highway, the system develops and designs four subsystems and six basic databases. By combing Gaussian model, GIS new technology and modern safety management method, the system realizes three major functions urgently needed by emergent response, which are quick function for dangerous substance and hazard installations, predictive function for disaster and accident consequence, accessibility for emergency response decision. The system would provide technical support for the emergent response of major dangerous chemical accident on the highway.
