Is the CTPP dead? The latest version I see of it was done by AASHTO rather than the feds and is only updated to the 2006-2010 ACS:

If so, is there any other place to get this level of data easily? Particularly interested in looking at mode share by PLACE OF WORK on a tract level. Can find data on mode share by residence, or by place or work on a county level, on American Factfinder. But nothing more detailed. What do MPO's do now for this kind of data?
