Abstract In urban systems, there is an interdependency between neighborhood roles and transportation patterns neighborhoods. this paper, we classify docking stations in bicycle-sharing networks to gain insight into the human mobility of three major cities United States. We propose novel time-dependent stochastic block models, with degree-heterogeneous blocks either mixed or discrete membership,...
