Traffic network density，population weighted average traffic proximity and location advantage are the three basic indicators of this paper. Based on the three basic indicators，this paper constructs an evaluation model of traffic dominance，comprehensively analyzes the scale，structure and access level of traffic network in Beijing-Tianjin-Hebei region from 2009 to 2018，reveals the pattern and evolution characteristics of traffic development and traffic dominance，and puts forward development suggestions. The results show that：（1）from 2009 to 2018，the transportation of all districts and counties in Beijing-Tianjin-Hebei region has developed in different degrees，and the gap of regional transportation development level has gradually narrowed，but the spatial difference is still obvious. From the perspective of the three basic indicators，the overall characteristics are：Beijing and Tianjin are the core of the circle structure，the development in south is superior to the development in the north，the south part develops faster than the north，the east part is higher than the west. （2）The traffic dominance of Beijing-Tianjin-Hebei region is gradually increasing. There are significant spatial differentiation and spatial correlation characteristics. The high value is stable in Beijing-Tianjin area. The low value is stable in Zhangcheng area in the north，and it is also common in Baoding，Handan and Xingtai. The traffic dominance of the weak traffic areas in the north and the eastern coastal areas has increased significantly，while the growth of the southern area and the southern section of Beijing Shijiazhuang corridor is small. （3）In general，Beijing and Tianjin are the first echelon of transportation development in Beijing-Tianjin-Hebei region，Shijiazhuang，Langfang，Tangshan，Qinhuangdao，Baoding and Cangzhou are the second echelon，Zhangjiakou，Chengde，Hengshui，Xingtai and Handan are the third echelon. （4）It is less likely that the traffic dominance of each district and county in Beijing-Tianjin-Hebei region can be homogenized，so it should be coordinated as a whole，adjust measures to local conditions，make up the short board，and develop reasonably.
