GIS Based Research On Road Transportation Management Of Dangerous Chemicals

Chemical industry always plays a main role in the national economic activities, and transportation of hazardous chemicals, as an important part of it, has attracted more and more attentions. Government has enacted various interrelated laws, regulations, ordinances to enhance the safety management of the transportation of dangerous chemicals as well as prevent and reduce the rate of accidents and protect people’s lives and property safety. In order to avoid the loss cost of accidents, some enterprises are also seeking solutions of reducing the accidents rate and the consequences of accidents.Unlike traditional transportation route optimization, when studying about the transportation of hazardous materials, we need to minimize not only the transportation costs, but also the transportation risk. The research of this paper includes four aspects.(1) Considering the effect of population distribution on the risk assessment of transportation of dangerous chemicals, on the basis of traditional risk measurement models, this paper combined GIS spatial analysis functions as an innovation. In order to apply this model into an actual case, the route data and population distribution data of Shanghai is used in the process of classifying the risk of transporting dangerous chemicals.(2) On the basis of risk analysis, this paper built the route transportation model of dangerous chemicals to give methods for solving the optimal path and reducing the risk of transportation.(3) After the discussion about the role of shutting down the high risk road in reducing the risk of transporting dangerous chemicals, this paper provided the optimal path of this issue on the basis of GIS.(4) In the end, this paper proposed a safety management system based on GIS. Through these assessments, a government agency can estimate the impact of alternative policies that could alter the carriers’ route choices.
