The Evaluation Studies of Regional Transportation Accessibility Based on Intelligent Transportation System: Take the Example in Yunnan Province of China

The transportation accessibility greatly represents and influences the regional social economic development. This study is based on the concept of intelligent transportation system which adopts the transportation distance range, transportation accessibility time and accessibility coefficient to be the quantitative evaluation index of intelligent transportation. By taking the example in Yunnan Province, we evaluated the regional transportation accessibility. This study uncovers that the transportation accessibility is obviously different among regions. At the end, the paper has proposed relevant solutions to existing problems.
