Abstract:

Traffic facilities are important resources for the future sustainable development of old industrial areas. It is of great practical significance to evaluate and study the spatiotemporal differentiation laws and mechanisms of traffic dominance. A comprehensive evaluation method based on traffic network density, traffic trunk line influence degree, and location dominance was constructed to measure traffic dominance. Taking Northeast China as the case study, the influencing factors and mechanisms of the overall pattern of traffic dominance were analyzed through network analysis, multivariable linear regression and geographic weighted regression. The results show that: (1) The overall traffic dominance of Northeast China is on the rise, and its spatial distribution pattern takes Harbin-Dalian line as the axis and presents a "core-periphery" structure. (2) The spatial differentiation of the overall traffic dominance of the study area is obvious. Most of the high value areas are concentrated along the high-speed railways, while the low value areas are mainly distributed in the east of Inner Mongolia and the north of Heilongjiang. The spatial difference is increasing gradually. (3) The fast traffic mode contributes a lot to the traffic dominance of Northeast China, and the influence of population carrying capacity on the spatiotemporal differentiation of traffic dominance is gradually strengthened. Expanding the traffic trunk lines and increasing the number of traffic hubs will help to improve the traffic dominance of Northeast China.

Key words: traffic dominance, location dominance, traffic trunk line influence degree, traffic network density, Northeast China
