Abstract: The level of integrated transport development has an important supporting role for the regional economy. In order to accurately assess the level of integrated transport development of a region, a three-tier evaluation index system containing 4 secondary indicators and 30 tertiary indicators was constructed by taking into account various influencing factors. And in order to reduce subjective influence, the cloud model was used to improve the analytic hierarchy process method to calculate the weights of evaluation indicators, and the TOPSIS evaluation model was combined to calculate the distance between each indicator of the evaluation object and the optimal indicator, in order to obtain the ranking of the integrated transport development level of each evaluation object. Taking the Yangtze River Delta (YRD) region of China as a case study, its integrated transport development level was evaluated by the proposed model. The results show that: in the YRD region, Jiangsu Province ranks first in terms of its high level of integrated transport development, Shanghai ranks second slightly higher than Zhejiang Province, Zhejiang Province ranks third with a lower score, and Anhui Province ranks the lowest. According to the calculation results and scores of various indicators, the Yangtze River Delta should combine with the actual situation of each province and city to make up for the shortcomings of the transport to achieve high-quality transport integration.
