Taking the countylevel cities of Xiangxi Autonomous Prefecture as the research object, this paper calculates the coordinated development index of traffic infractructure and tourism development in Xiangxi Autonomous Prefecture, and analyses the coordinated development level between these two aspects. The results show that the average coordinated index of traffic infractructure and tourism development in Xiangxi’s counties and cities is low, and it shows an obvious fluctuation from year to year; there is an unbalanced development of the traffic infractructure and tourism development in different cities and counties like Jishou City, Fenghuang County, Longshan County and Huayuan County, and the degree of coordinated development between transportation infractructure and tourism system in Xiangxi is not high on the whole. In the development of traffic infractructure, Xiangxi Autonomous Prefecture should give full consideration to tourism, improve external tourism channels, build intrastate tourism trunk line network, enhance the connectivity of scenic spots, and improve the tourist highway of scenic spots.
