Figure 5
The figure consists of four line charts arranged in a two-by-two grid comparing pedestrian and car accessibility across two years, 2007 and 2017. In all four charts, the horizontal axis is labeled Accessibility percentage and ranges from 0 to 100 in increments of 20. The vertical axis is labeled Population percentage and also ranges from 0 to 100 in increments of 20 percent. Each chart contains two lines: a blue curved line labeled “Lorenz curve” and a straight orange diagonal line labeled “Equity”. A legend identifying these two lines appears below each chart. In all the charts, the “Equity” curve starts at (0, 0) and ends at (1000, 100), and the “Lorenz curve” starts at (0, 0), and ends at (100, 100). The top-left chart is titled Pedestrian accessibility 2007 and reports a Gini index of 0.60. The Lorenz curve lies well below the equity line for most of the range, passing through (40, 8), (60, 19), (82, 40), (91, 60), with slight fluctuations, indicating higher inequality in pedestrian accessibility in 2007. The top-right chart is titled Pedestrian accessibility 2017 and reports a Gini index of 0.51. The Lorenz curve is closer to the equity line compared to 2007, passing through (40, 10), (60, 21), (78, 40), (88, 60), indicating a reduction in inequality in pedestrian accessibility by 2017. The bottom-left chart is titled Car accessibility 2007 and reports a Gini index of 0.60. Similar to pedestrian accessibility in 2007, the Lorenz curve shows a pronounced deviation below the equity line, smoothly passing through (40, 8), (60, 18), (82, 40), (91, 60) The bottom-right chart is titled Car accessibility 2017 and reports a Gini index of 0.55. The Lorenz curve is closer to the equity line than in 2007, passing through (40, 10), (60, 20), (79, 40), (88, 60). Note: All numerical values are approximated.Lorenz curves for car accessibility and pedestrian accessibility in 2007 and 2017. Source: Authors’ own work
