On the basis of rationally setting up the system of evaluating indexes and selective models in main hub layout, the two layers of evaluating indexes are studied in quantity. In the first layer of the evaluating indexes, for example, the adaptability, harmony, economy, convenience, sociality and performance of station layout, some results of domestic and overseas quantitative research on the evaluating indexes of highway main hub stations layout are introduced. The negative exponent is used in the second layer of evaluating indexes, such as stations scale adaptability, station developing space, harmony with other transport systems and urban general plan, the condition of vehicles in and out, the condition of passengers and owners of cargo coming into stations, the impact on the environment, etc. Then, the values of evaluations are revised by reasonable coefficient. The values will be controlled from zero to one. At last, the two layers are integrated and quantified so that the values results of evaluating indexes are more scientific and more reasonable.
