Research on spatio-temporal dynamics of urban leisuring places based on floating vehicle tracking data and POI
Urban leisure facilities,an important part of urban sustainable development and public health,get increasingly attentions by citizens with the rapid development of urbanization and the continuous improvement of urban facilities.The dynamic rules of spatial-temporal changes of urban leisuring places were furtherly explored in this paper by analyzing the tourism characteristics of urban residents,combing the Point of Interest(POI)of urban leisuring places,and using spatial clustering and Latent Dirichlet Allocation(LDA)text analyzing algorithms on the basis of floating vehicle tracking data.The results show that the leisuring places generally are"increasing first,then decrease,and then increasing again",the changing is consistent with the behavior of urban residents.It is not only help to enrich the realistic theory of the coordinated development of urban people and land,but also help to explore the spatio-temporal evolution of urban leisuring places from the perspective of dynamic traffic trajectory,which is of great significance for optimizing the layout of urban functions by analyzing the spatial distribution of urban leisuring places and the functions of their spatio-temporal dynamic change rules.
