Low-carbon transportation has become an important topic due to global climate change and the increasing vehicle volume in China.Learn from the welfare performance formula of Daili,the evaluation indicator system,which includes energy efficiency index and operation index of low-carbon transportation,was developed based on the basic principle of orientation,data availability and comparability.Meanwhile,the evaluation model of regional lowcarbon transportation was established through the grey relational analysis and fuzzy method.The proposed evaluation model was used to evaluate the low-carbon transportation of Jiangsu.The results show that the level of low-carbon transportation of Jiangsu is good in 2010.The key points of low-carbon transportation were as follows:low-carbon road should be emphasized,carbon-tax regulation should be strictly implemented and the mass transit structure should be further optimized.
