Abstract: This paper studied the reasonable corridor scale which connects service facilities in passenger transport terminal .Based on the influence of corridor length and width on pedestrian flow ,the simulation schemes were designed u-sing simulation software .By using pedestrian flow data output from the simulation software ,the trend curves of pedestri-an flow data were established .On the one hand ,the differences of those curves were analyzed ;on the other hand ,the K-W tests of the statistical data were given in order to analyze the differences of the pedestrian flow data .Based on analysis results of the curves comparison and K-W test ,the divergent role of corridor length and width on pedestrian flow were an-alyzed .On this basis ,the reasonable width of unidirectional corridor is 4 meters ;the reasonable width of bi-directional corridor is 8 meters ;and the reasonable corridor length is 50 meters .
