Abstract: The Sino-Singapore Tianjin Eco-city is the sign of the start of eco-city planning and construction in China. Since its completion of the planning in 2007, the occupational-residential comprehensive function zone with the characteristics of low-carbon and ecologicalization as the core of the ecocity has been constructed for more than ten years. The evaluation of its construction effectiveness is of great significance for subsequent construction and optimization of eco-city development model. As an important aspect of eco-city, ecological transportation is an important content of eco-city construction evaluation. Here, we assessed the construction of ecological transportation system in the Sino-Singapore Eco-city. Based on the connotation of ecotraffic, two models, AHP and Delphi, were chosen as the basic evaluation methods. We constructed evaluation index systems of urban ecological transportation, including travel mode, travel convenience, travel environment, social environment, and spatial layout. We collected data on the objective construction progress of typical subjects of the Sino-Singapore Tianjin Ecocity in 2017 and 2020, and conducted a questionnaire survey on the satisfaction of residents. The results of the two phases of were quite similar. The total evaluation scores in 2017 and 2020 were 6.74 and 6.81, respectively, indicating that the quality of the ecological transportation system is relatively stable after the completion of the eco-city construction. In the sub-items, higher scores were found in travel convenience and travel environment, because of their reasonable planning and construction process and residents’ good feel to use. Lower scores were in travelling mode and spatial layout construction, due to the substantial differences between internal development and construction process of the eco-city, and weak points in the construction. We found the problems and put forward the corresponding promotion strategies, which is useful for the future construction of Sino-Singapore Tianjin Eco-city and other urban ecological transport constructions.

Key words: eco-traffic, AHP, planning and construction assessment, satisfaction survey, Sino-Singapore Tianjin Eco-city.
