Fig. 4: Explain social mixing with transportation.

(a–e) Estimating the place level social mixing with transport modes with and without density control (See SI Table S4 for the full results, including effects of POI counts by types). f Impact of total change of trips by each transport mode on place-level social mixing (Eq. 7, See Table S5 for full results). g Equation 6 is repeated within each functional area. Table S11 shows the distribution of transportation opportunities.
