Abstract： The current new development concept has new requirements to the city clusters' transportation development. As an important city cluster among the metropolitan areas along the Yangtze River Economic Belt, Chengdu-Chongqing city cluster possess the strongest economic strength in the western China. This paper first analyzes the three distinctive development features of Chengdu- Chongqing city cluster: high ranking status, entirely inland type and abundant tourism resources among other things. The paper identifies three transportation issues — badly needed improvement on the international travel connectivity, imbalance and ineffective transportation services, and severe problems in lacking of communications among administrative offices as well as the unnecessary internal competitions. Finally, the paper proposes five future transportation development strategies for this city cluster: strengthening the large intra- and inter-modal terminals' development, improving inter-city railway network, enhancing the functionality of secondary terminal functionality, promoting the joint development and sharing of infrastructure facilities and policies, supporting the transportation development in the metropolitan areas of Chengdu and Chongqing.
