Understanding the dynamics of daily mobility patterns is essential for the management and planning of urban facilities and services. Previous studies have utilized taxi trajectories collected from the Global Positioning System (GPS) to model various types of urban patterns, such as identifying urban functional regions and hot spots. However, there is limited research on how the results of these studies can be used to inform real-world problems in urban planning. This research examines the development of sub-centers in Nanjing, China based on Taxi GPS trajectories. The results indicate a clear separation between the urban center and the sub-centers. In addition, we also clustered the time series of taxi pick-up locations to model dynamic urban movement and identify outlier patterns. The results demonstrate the importance of considering human mobility patterns in identifying urban functional regions, which provides valuable input for urban planners and policy makers.
