Exploring spatio-temporal characteristics of air passenger flow in the Beijing-Tianjin-Hebei region based on ticket data

Air passenger flow can show the spatial connection among cities. Based on the ticket data of major airports in Beijing-Tianjin-Hebei region, this paper systematically explored the temporal and spatial distribution characteristics of passenger flow in this region, drew the OD map among this region and other cities, and analyzed regional differences and connection characteristics among cities. Experimental results show that the passenger flow of airports in the Beijing-Tianjin-Hebei region is uneven in time and space. In terms of space, the regional distribution of air passenger flow is extremely unbalanced. The air transportation status in the east is extremely prominent, while the western part is relatively strong, and the central and northeast parts are relatively weak. In terms of time, the major airports in the Beijing-Tianjin -Hebei region have obvious peak and low peak periods, and the distribution of passenger flow direction in different time periods is also slightly different. The research results provide a basis for the analysis of population flow and economic relationship among urban agglomerations, and provide reasonable suggestions for traffic planning and passenger travel.
