Abstract:This paper points out that the tranditional axial model does not consider the key factor of the propertied of buildings around subway stations, however, different buildings have different generation and attraction of pedestrian activities. Then the paper selects building height and building density as two indexes to modify the axial model. According to the difference of building density of 500m radius area around a subway stations’ entrances and the domestic and foreign relevant rules for high-rise building regulations, the paper draws the conclusion of the applicable condition of the modified model. At last this paper compares the modified model’s applicability of subway stations in Shanghai and Nanjing, and finds out the accuracy of modified model is both higher than 91%, so the conclusion is drew that the modified model and applicable condition can be widely-used in different metropolis. This research provides theoretical support to the design of passageway width, fare gates number, parking facilities and bus station layout outside the subway station.
