Mobility Horizons


I’ve been working on ways of mapping infrastructure as “ready-to-hand”. Instead of registering the hardware of the infrastructure, I want to register it in terms of its use. At the moment I’m playing with Stefan Wehrmeyer’s Mapnificent  tool, which uses public transport data (in Auckland’s case from MAXX) to estimate how far you can get in a given time window. The tool exports in GeoJSON, which I’m then compiling using QGIS. A few things I’ve noticed: the initial walking circle is drawn without any knowledge of barriers to mobility (it’s happy to let you walk on water and through buildings). Secondly, there are large parts of the site where you’re more than ten minutes from a connection to public transport, so your mobility horizon is set solely by how far you can walk. Thirdly, bus stops and train stations are attractors — from a number of locations you can end up at these points, so they appear darker. Given the intensity of the road and rail infrastructure here, it’s odd to see how disconnected from the network you can be. I’m going to try cleaning this up a bit.
