季节时空交互视角下老年人公交移动性的影响因素研究——以芜湖市为例

INVESTIGATING THE FACTORS OF ELDERLY’S BUS MOBILITY BASED ON THE SEASON AND SPACE INTERACTION: A CASE STUDY OF WUHU

公共交通是我国老年人出行的主要交通方式之一,公交移动性是衡量老年人生活质量和幸福感的重要指标。从季节和空间双重维度分析老年人公交移动性的影响因素有助于深入理解老年人出行行为机制。利用公交刷卡数据和地理探测器方法分析了季节时空因子对老年人公交移动性的影响。研究发现:①不同季节中空间因子对老年人移动频率、移动半径和移动熵的解释力和显著性存在明显差异,对老年人移动性影响机制的分析应考虑时空变化的双重影响;②不同空间因子之间以及季节与空间因子之间的交互作用可以显著增强对老年人移动性空间分异的解释力,考虑多个因素的协同效应对深入理解老年人行为有一定帮助。研究试图拓宽老年人移动性影响因素的分析思路,为老年宜居城市建设和城市移动性规划提供重要支撑。

Public transportation is a main mode of transportation for the Chinese elderly, and bus mobility is an important factor that influence the quality of life and well-being of the elderly. Analyzing the factors of elderly bus mobility from the seasonal and spatial dual dimensions helps to understand the mechanism of elderly travel. This paper analyzes the influence of season and spatial factors interaction on the elderly’s bus mobility by using bus card swiping data and geographic detector methods. The study found that: 1) There are significant differences of the spatial explanatory factors and significance on the movement frequency, movement radius and movement entropy of the elderly in different seasons. The influence mechanism of the bus mobility of the elderly should be consideredin the dual aspects for temporal and spatial changes;2) The interactive relationship between different spatial factors and between seasons and spatial factors can significantly enhance the explanatory power of the spatial differentiation of the elderly’s bus mobility. Considering the synergistic effect of multiple factors is helpful to understand the elderly’s behavior. Research has broadened the analysis of factors affecting mobility of the elderly, and can provide important support for theurban mobility planand the construction of livable cities for the elderly.
