The method decomposes the commuting flows in the city in four categories: the integrated flows (I) from hotspot to hotspot, the convergent flows (C) to hotspots, the divergent flows (D) originating at hotspots and finally the random flows (R) which are neither starting nor ending at hotspots. For each city with its origin-destination matrix, we can compute the importance of each commuting flow category and get a simple picture of the mobility structure in the city.
