Fuzzy synthetic evaluation model of transportation routes of dangerous goods

In order to optimize the routes of TDG (transportation of dangerous goods) by multi-level fuzzy synthetic evaluation method, the ecological environment, densely populated district and traffic situation were determined as major factors that influence the safety of TDG to ensure transportation safety and to reduce transportation accidents of dangerous goods, a fuzzy synthetic evaluation model was established. The safe degrees of roads G108, G210 and G316 were computed with the method. The result shows that G316 is relatively safe, which accords with the evaluation result of road experts. The model is effective for finding an optimum vehicle trip route to reduce the harm degree of TDG.
