Illustrations of a an example of using a radiation mode to estimate population flow from mi (source) to mj (destination), which considers total population in the circle centered at mi and touching mj excluding the source (mi) and the destination (mj) population. More population in the circle represent people in the mi have more attractive (e.g. opportunity of jobs), and it decreases mobility propensity from mi to mj; b network connectivity structure of human mobility estimated by a radiation model to represent spatial interaction
