The disclosure relates to a method for evaluating a global transportation accessibility index (GTAI) based on raster data on a large scale. The method includes: step 1: determining a macro-scale range of GTAI evaluation, dividing a remote sensing (RS) map in a raster form on a macro-scale, and obtaining raster-scale data; step 2: extracting a relevant index, and normalizing; step 3: calculating a population and transportation density index (PTDI); step 4: calculating a transportation convenience index (TCI); and step 5: calculating the GTAI based on the PTDI and the TCI.
