The Impact of Urban Rail Transit on the Spatio-Temporal Structure of Individual Daily Activities: A Case Study of Kunming, China

The changes in urban spatial structure caused by urban rail transit construction have led to differences in the daily activities of residents within the same urban area. The spatial structure of residents’ activities reflects the impact of urban external space on residents’ daily activities. From the perspective of micro-individuals, we can grasp the changes in urban spatial structure from the regional differences in the living space. Based on the 2016 Kunming travel survey data, this paper establishes a cox proportional hazard model to compare the differences in activity patterns between residents along the track. The study found that the land use construction along the track is relatively complete, providing residents with rich employment and activity opportunities and convenient transportation facilities. The construction of living facilities around non-rail transit is relatively simple, the dependence of cars is high, the commuting travel restrictions are strong, and people’s activity space is more scattered.
