It seems that everyone who analyzes historical NextBus data has a different way of archiving their data. There are lots of ways one can use GIS to analyze this data, from creating movies showing the pulse of the transit system, to analyzing on-time performance, to finding bottlenecks. In that vein, I’ve created a short Python script that fetches NextBus data and puts it into a PostGIS database for analysis. You can download the latest version here.
