Poster Abstract: Human Mobility Modeling on Metropolitan Scale Based on Multiple Cellphone Networks

Modeling human mobility paerns from CDR(Call Detail Record)data is an ecient way to understand the eects of human movementson transportation, society and the environment. Previoushuman mobility models are focused on single cellphone networkCDR data. In the poster, we present a framework to model humanmobility paerns on CDR data from multiple cellphone networks.Based on data analysis from multiple cellphone networks, our targetis to provide statistic features and mobility paerns in multiplegranularities of spatio-temporal resolutions to support novel urbanservices. Compared with previous work, our approaches aim toestablish a more diverse and more stable framework, which is acrucial prerequisite for various smart city services and applications.
