Research on the accessibility of rural transportation in the context of rural revitalization: a case study of Jiang'an

Transportation is the fundamental guarantee and important carrier for the implementation of the rural revitalization strategy. This article selects 189 administrative villages within 14 townships in Jiang'an County, Yibin City as the research object. Through the cost distance analysis method, a accessibility measurement system for villages and towns in Jiang'an County is constructed, and data is collected and analyzed using GIS software, Gaode Maps and other platforms. The research results indicate that there are significant differences in transportation accessibility in Jiang'an County, with higher accessibility in towns near the urban area than in towns far away from the urban area. The accessibility shows a clear direction of high-speed and trunk road networks. Among them, the village town, town city, and village city in Yibin City have basically formed a "45-60-90" minute three circle pattern of cars. Administrative villages can reach the nearest township within 45 minutes, Jiang'an County urban area within 90 minutes, and each township can reach the central urban area within 1 hour.
