Here is an interactive driving time heatmap for Detroit. It visualises the time it takes to drive from Downtown Detroit to its outlying neighbourhoods. I thought it would be cool to see the artery effect of fast roads visualised on a choropleth. As the Motor City, I also thought Detroit would be an obvious choice for this.
As expected, the major roads and highways do indeed create an artery-style effect in the map below. All of Downtown is within five minutes driving time. Midtown, Corktown, Woodbridge, Eastern Market, New Center and North End are all within a mere ten minutes drive.
The map also makes it possible to spot places that are pretty inefficient to get to. For example, the Charter Township of Clinton to the north-east takes about 35 minutes to get to and is 25 miles away. This is visible as the swathe of green encompassing the township on the map. However, the Plymouth Charter Township, west of Downtown, is the same distance and takes ten minutes less time driving time.
Another interesting quirk of Detroit is that its Downtown area straddles the US-Canada border. This means that although Windsor is only on the other side of the Detroit River, driving times are disproportionate to the short distance. We can see that visualised in the map above as the darker colours emanate out to the north-west, but do so to a lesser extent across the border.
