According to the needs of risk assessment, path planning and emergency rescue of hazardous chemicals transportation, a risk assessment and decision support system of hazardous chemicals transportation was designed, including system structure, implementation process and main functions. The feasibility analysis of key technologies was carried out. This system took Geographic Information System (GIS) as the support platform, and integrated multi-source information such as hazardous chemicals, global positioning system (GPS), geographic environment, Meteorological information, etc. Based on classical pollution diffusion models and relevant domestic and foreign standards, the index system of transportation risk assessment was built. Then the quantitative index of risk assessment and the early warning sign could be given, and the hazard area of the chemical accident was determined. At last, this risk assessment and decision support system provided suggestions on route optimization for hazardous chemicals transport, which could be severed as scientific basis for emergency rescue and command decision.
