The Study On Transportation Route Choice For Flammable And Explosive Hazardous Materials

The most important question of flammable and explosive materials transportation is how to ensure their safety during transport, do everything possible to reduce the transport accidents and other causes of human and environmental hazards. Based on the inflammable and explosive materials transportation routes choice class discussion, flammable and explosive materials in the hazardous characteristics are described, based on the systematic identification and analysis of the inflammable and explosive materials during transportation of the risk factors; established a flammable explosive materials transportation routing evaluation index system, index system considering the transport accident on human, environmental and property impact, and highlighted the environmental impact of the cost, environmentally sensitive areas will be divided into three categories:scenic spots and nature reserves, agricultural eco- areas, water sources, were given weight, making the index system is further improved; and using AHP and expert investigation of the index system for qualitative and quantitative evaluation and analysis, built to transport security costs and transportation costs combined for the goal of easy Selection burning explosive materials transportation quantitative evaluation model, including flammable and explosive goods transport accident rate estimates, the scope of the accident population estimates, environmental impact and cost of property damage estimates and a comprehensive selection of location schemes. The model used by the region from Chengdu to Ya'an route selection of road transport liquefied gas project case study to verify the inflammable and explosive materials and scientific and practical method to select. The evaluation method and model for the safety of road transport flammable and explosive items accessibility provides a reference value.
