Analysis of spatiotemporal characteristics of intercity travel on holidays in urban agglomeration based on mobile phone signaling data

Abstract

The coordinated development of urban agglomerations has become a national key development strategy, and the realization of this strategy must be supported by an efficient and scientific transportation system. The analysis of the spatiotemporal characteristics of intercity travel in urban agglomerations is the basic support for the study of intercity transportation policies, planning and construction, and operation management. Based on massive mobile phone signaling data, this paper extracts the intercity travel data of the Beijing-Tianjin-Hebei urban agglomeration, and reveals the spatiotemporal characteristics of intercity travel from different perspectives. The results of the study show that there are two distinct peak periods for intercity travel during holidays. Holidays can be divided into three categories according to time characteristics: holidays with traditional customs such as family reunion (such as Spring Festival, Mid-Autumn Festival), long holidays (such as National Day, Labor Day), and short holidays (such as Ching Ming Festival, Dragon Boat Festival). During the first peak travel period of holidays, from the inside to the outside of the Beijing-Tianjin-Hebei urban agglomeration, the spatial distribution of the inflow and outflow of intercity travel shows highest outflow-higher outflow-highest inflowhigher inflow- basically flat inflow and outflow space structure. The second type of holidays (Labor Day, National Day) in this hierarchical structure is the most obvious. The research results of this paper provide a scientific reference for the planning of the intercity transportation system of urban agglomerations during holidays.
