(a) Example of geometric (black dash) and route (red solid) walking distance from a residential point (yellow) to an urban park destination (red) calculated using Google Maps Distance Matrix API. The route walking distance and time are also indicated. The base map is from Open Street Map (www.openstreetmap.org). (b) Scatter plot and linear regression of route and geometric distances from all SB units to the nearest urban parks. The estimated formula for linear regression is also indicated. The two distance measures have a high correlation with R2 of 0.97. On average, the ratio of the route to geometric distance is about 1.52 in high-density urban areas of Hong Kong.
