Roundabout database

[tradephoric]

A comprehensive google KML file of over 1,700 roundabouts in the USA & Canada with slider data when each roundabout was constructed (roughly).  Roundabout data subdivided by size (single lane, double lane, tripple lane, and mini-roundabouts).  This took quite a while to put together and most of the data was taken from Kittelson's roundabout database.

Let me know what you think.  Thanks
