Visualize the Coverage of Nearby Transit

Use this application to visualize the the coverage of public transit in various locations. Drag to move, and click to change the central point. The light blue area gives a rough idea of the coverage from transit-related uses with 10km of a central point. It shows everywhere within 240m of a transit station, be it a passenger railroad station or a bus stop. This is roughly the distance that someone could walk in 3 minutes. It is a very simplified view of transit coverage in a place, since it doesn't take into account routes, frequency, accessibility, or type of transit.

I used the open-source project OpenStreetMap via the Overpass API to get information on the location of transit stations, and I used the javascript library Leaflet to present those features on an interactive map. A version of this app is available on my github.

OpenStreetMap is amazing, and if you are interested in learning more or getting comfortable with the project, I recommend you check out the OSM Queries Tutorial, or run your own queries from Overpass Turbo.
