[OSM-talk] OSM completeness

[Eleanor Stokes]

Hi list,
Not sure if this is the right place to post--but I just got into using OSM and 
am hoping to utilize it for some of my research.  I need to get some kind of 
completeness metric for each of the cities I am looking at (about 200 of them).  

Does anyone happen to know of completeness analyses
across cities in different regions that have been performed?  
I'm particularly interested in the completeness of the
road datasets in OSM.
