For illustration water, railways in addition to interstate highways are given a high friction grade because they are really difficult to walk across. Conversely a commons is given a depression friction grade because it would hold upwards easier to walk through.
If you lot desire to a greater extent than information nearly how walkshed.js industrial plant therefore this YouTube video, Walkshed.js: Measuring Walkability alongside Client-side Raster Processing, provides a detailed trouble organisation human relationship of how walkshed.js calculates walking times inwards the browser.
