This is a hobby project to extract useful information about the Buenos Aires Subte network from OSM. The objective is to find "hard" facts to back observations about the network.

Examples would include:

• a map with the city colored by walking distance to the nearest subway station,
• a map with the city colored by the closet subway station,
• a map showing the number of train changes required for "typical" travel ("typical" would need some definition),
• a map showing typical travel times ("typical" would need some definition).

The same approach could be applied to other cities, which would then allow a comparison of the different networks.
