Analysis of street network orientation in cities

Continuing his analysis of street grid-iness in cities around the world, Geoff Boeing sorted cities by the amount of order in their street networks: Across these study sites, US/Canadian cities have an average orientation-order nearly thirteen-times greater than that of European cities, alongside nearly double the average proportion of four-way intersections. Meanwhile, these European cities’ streets on average are 42% more circuitous than those of the US/Canadian cities. North American...

Stacked bus routes on a map

Speaking of 3-D usage on maps, here’s a map of bus routes in Singapore stacked one on top of the other. I’m not sure it’s especially useful to find individual routes as intended, but the overall distribution of routes seems like it might be interesting to someone familiar with the area. Or, maybe it’s world’s greatest roller coaster. Tags: bus, directions

Interactive to see street orientation everywhere

After seeing polar charts of street orientation in major cities, Vladimir Agafonkin, an engineer at Mapbox, implemented an interactive version that lets you see directions for everywhere: Extracting and processing the road data for every place of interest to generate a polar chart seemed like too much work. Could I do it on an interactive map? It turns out that this is a perfect use case for Mapbox vector maps — since...

Street network orientation in major cities

Using OpenStreetMap data, Geoff Boeing charted the orientation distributions of major cities: Each of the cities above is represented by a polar histogram (aka rose diagram) depicting how its streets orient. Each bar’s direction represents the compass bearings of the streets (in that histogram bin) and its length represents the relative frequency of streets with those bearings. So you can easily spot the gridded street networks, and then there’s Boston...
