Application of Transportation Superiority in Beijing-Tianjin-Hebei Region Based on High-Resolution Satellite Remote Sensing Data

Coordinated development of the Beijing-Tianjin-Hebei Region is a national strategy of China, while the most import aspect among the strategy is transportation integration. By using GF-1, ZY-3 satellite data, this paper produced the latest traffic infrastructure dataset, constructed the evaluation system of transportation superiority degree through the technical indicators such as the distribution of transportation infrastructure, the density of traffic network, the influence degree of traffic trunk line, and the location superiority degree. The results show that the transportation superiority degree in Beijing-Tianjin-Hebei Region presents a “bias normal” distribution characteristic. 14.8% of the county-level administrative units have outstanding transportation advantages, with better economic development. Near 9.4% of the county-level administrative units are at an obvious disadvantage in terms of traffic conditions, and about 75.7% units are at the middle or above the middle level of the evaluation samples. The results could be introduced to the transportation planning and supervision of this region.
