In my mental model of a walkability map it’s not enough to know how far away something is, but also how long it takes me to get there. My perceptions of the same distances, but with different walk times, are much different. There are realities that slow me down like intersections, buildings, water features, or just the gridded nature of a neighborhood, making the temporal terrain of a place highly varies.<\/p>\n
But what if we could smooth out that temporal variability? Is there a way to visualize this cartographically? Can we take all those elements of friction, render them as time-aware walkability areas, and then warp them into spatially normalized sequential time bands? Well let’s try it!<\/p>\n
