Ireland and Dublin Street Orientations

Based on the work by:

Geoff Boeing: Comparing City Street Orientations

Rixx: Street Orientations

The graphs show the percentage of streets that run in a certain orientation. So for a grid based city like Chicago, there will be a heavy bias in north/south and east/west streets. Bearing in mind north and south will be the same (unless there are one-way streets, which only count in the direction they run in).

But for older cities that formed naturally, without modern city planning, the streets should be more varied.

Dublin Postcodes:

Some areas are clearly impacted by large motorways running through them.

And for non-Dubliners, a map of the postal district boundaries:

I updated the script by Rixx, so that it would take a ShapeFile as an input with a few caveats (it must be WGS84, it must have an attribute that has the are name and it must be called settl_name).
