Figure 3
The figure consists of four maps arranged in a two-by-two layout where the top-left panel is labeled “Pedestrian 2007 with the letter A”, the top-right panel is labeled “Pedestrian 2017 with the letter B”, the bottom-left panel is labeled “Car 2007 with the letter C”, and the bottom-right panel is labeled “Car 2017 with the letter D”. Each panel displays the same urban boundary outlined in black with internal street patterns shown in light grey, parks shown as green filled areas, and accessibility values represented by a color gradient ranging from very light pink through darker pink to deep purple indicating increasing accessibility, where the pedestrian maps show accessibility values labeled as 0, 0.45, 0.92, 1.53, 3.20, and 52.72. The car maps show accessibility values labeled as 0, 1.39, 2.16, 2.57, 3.05, and 13.05, north direction is indicated in each panel by the letter N with an upward arrow symbol, and a distance scale bar appears below each map showing 0, 1.5, and 3 Kilometers. Comparison shows that darker purple areas, indicating higher accessibility, expand noticeably from 2007 to 2017 for both pedestrian and car travel modes, especially in the central and eastern parts of the urban area.Levels of pedestrian and car accessibility to UGSs in 2007 and 2017. (a) Pedestrian Accessibility in 2007; (b) Pedestrian Accessibility in 2017; (c) Car Accessibility in 2007; and (d) Car Accessibility in 2017. Note: Accessibility levels are classified using quintile thresholds derived from the 2017 data. Colors represent relative accessibility ranks based on these 2017 breakpoints for both years, with darker shades indicating higher relative access (top 20%) and lighter shades indicating lower access (bottom 20%).
