CDF of basin size and population distributions for 9 cities in the year 2016. a, Morning and daytime basin size distribution in 9 cities (Tokyo, Osaka, Nagoya, Fukuoka, Sapporo, Sendai, Hiroshima, Okayama and Kumamoto), where the size definition is the number of combined squares. CDFs of the morning commuter rush hour are approximated with a power distribution of the exponent \(-2.4\). b, The afternoon size distribution can be approximated by the exponential distribution (the dotted line). c, In the morning rush hours, CDFs of population of moving people in the basin follow a power distribution of exponents \(-1.2\), where the population in the basin is normalized by the average population in basins. d, The number of people moving in the basin during the morning rush hours is proportional to the square of the size of the basin. Note, (All results are consistent with those shown in Ref. Shida et al. (2020) for the year 2015.)
