Abstract: The delayed development of transport is an important factor restricting the development of mountain areas. Quantitative assessment of transportation accessibility in mountainous areas is significant for understanding the transport spatial patterns and the development of transport in the future. This paper develops a transportation accessibility evaluation model for mountainous areas using three core factors. They are technical grades of transport facilities, time distance between the evaluation area and the central city and road density of the evaluation area. It also uses an index which is named traffic friction coefficient to improve the accuracy of transportation accessibility assessment in mountainous areas. Taking Liangshan region of Sichuan Province as an example, the transportation accessibility was computed by the model. The results show that the area with poor transportation accessibility and very poor transportation accessibility in Liangshan area occupies 61.60% of the total land area, and the area with better spatial accessibility and satisfactory transportation accessibility in Liangshan occupies only 15.49% of the total land area. The result also proves that the model developed in this paper has a high accurary and it is valuable for the mountainous areas of China.

Key words: Liangshan region, mountain area, traffic friction coefficient, transportation accessibility
