The transportation industry is a concentrated place of energy consumption and carbon emissions. The development of low-carbon transportation has become a new industrial form of developing a low-carbon society. The research is based on the construction of the "dual carbon" goals, and constructed a fuzzy comprehensive evaluation system with the first-level index layer of transportation infrastructure energy efficiency and development and operation, which explore the effect of low-carbon construction after the implementation of urban low-carbon transportation. First, the study used the objective function method to obtain the combined weights of the indicators combined with the AHP-CV method; secondly, according to the functional objectives of low-carbon transportation construction, it establishes five secondary indicators of subordination and development, including infrastructure management, transportation and tools, transportation system construction, transportation environmental protection policies, low-carbon transportation environment. Finally, it selected Harbin, which a typical low-carbon city in Northeast China, to dynamically evaluate the development level of low-carbon transportation from 2017 to 2020. The results show that: In the selected years at the later stage of low-carbon implementation, the development of low-carbon transportation showed a weak upward trend. And the final degree of membership is "medium, good", which is consistent with the actual deployment of low-carbon transportation in Harbin in the past three years, and reflects the rationality of the early subject selection. In addition, the impact of the 2020 epidemic and the positive drive of the "dual-carbon" response have a significant impact on low-carbon indicators. According to the results of the grading index membership degree, it is recommended that the development should focus on continuing to promote the application of low-carbon transportation, enhancing citizens' low-carbon awareness and rationalizing the construction of a low-carbon urban transportation system. Finally, the results of the model is consistent with the status, which can provide a reference for the construction of low-carbon transportation areas under the background of the "dual carbon".
