Traffic is a prerequisite factor for the development of tourism. It’s also a basic factor for travelers’ travel considerations. However，for a long time，traffic factors are generally considered as external variables that influence the level and scale of regional tourism development. In recent years，along with the continuous improvement of the integrated transportation system，the two have seen the trend of integration and development. The focus is on the continuous display of the tourist functions of transportation，and the continuous emergence of special forms of tourism and transportation products. In February 2017，the Ministry of Transport and the National Tourism Administration jointly issued the Several Opinions on Promoting the Integration Development of transportation and Tourism，and clearly proposed to speed up the formation of a new pattern of integration development between the two. Hainan Province is the first all-for-one tourism demonstration provinces in China. The “Sanya” tourism economic circle is an exemplary area for Hainan Province to promote the development of all-for-one tourism. It is the most typical area where tourism and traffic are integrated and developed in the nationwide scale. Taking the “Greater Sanya” tourism economic circle as an example，this paper analyzes the existing problems of tourism traffic in “Sanya Sub-region” and puts forward the measures and suggestions for the deep integration of tourism and transportation.
