| Abstract: | The importance of nodes was calculated with main component analysis strategy.This method could cover the information of all indexes comprehensively and also eliminate the mutual influence of the indexes so that the analysis results could be more objective and truthful.The layout that combines importance of nodes with area location was improved to eliminate the defect that the traditional node importance model determines the weights subjectively and lack of coordination among indexes.The strategy was used fo... |
| Keywords: | transport economics comprehensive transportation channel main component analysis importance of nodes comprehensive transportation planning |
