Fig. 4

We first took a statistical analysis and plotted mean PCE accessibility in 40 counties by categories of PCE, include (a) TCGS, (b) NERPE, (c) ERPE. The distribution of the mean PCE accessibility in 40 counties were plotted using a box plot, with the five horizontal lines from top to bottom indicating the maximum, upper quartile, median, lower quartile, and minimum of the data, respectively, the method of significance test and the meaning of * are consistent with Figs. 2 and 3. We also adopted a simple linear regression analysis and plotted the regression results in 40 counties by categories of PCE, include (d) TCGS, (e) NERPE, (f) ERPE, the accessibility gaps between accessing PCE by walking and driving is large, and to make the regression plots clearer and more readable, we have taken a logarithm with a base of 10 for all the data used in (d). The distribution of the mean PCE accessibility in 40 counties were plotted using a scatter plot, the solid black line indicates the fitted straight line, the gray area indicates the 95% confidence interval, and the dashed black line indicates the marginal of equal PCE accessibility in both models, with greater PCE accessibility for driving above this line indicates and greater PCE accessibility for walking below this line.
