FHWA Planning developed a report on how to convert the "usual/last week" data
from CTPP to a "yesterday" measure typically used in household travel surveys.
The report uses NPTS to do the conversion, so I would imagine it would be a
useful source for you. I believe the name of the report is "Conversion
Factors for CTPP Data" or something like that. I would contact Sheldon Edner
at 202-366-4066 or someone on his team. I believe his email is
sheldon.edner(a)fhwa.dot.gov, and I am copying him on this.

I'm interested in combining npts and census data for 1990.
Can anyone direct me to studies or sources on this? studies that
have done this or sources that explain how to do it- I appreciate

Will the data fields for Stf 1, data by block level,
be the same as they
were in the 1990 census? Or can anyone tell me where to find out. I have
looked through the Census web site.
