Rolf--I am posting this query to the planners listserve (TMIP) which
might be another good place to cast for historic data. I would not be
surprised if some of the bigger regions might be able to go back to 1980
and even 1970. I would however be surprised if much would turn up in
the way of digital files but just knowing what is there and where to
look is valuable information in its own right.

Subject: [CTPP] Long-term data on job locations

Hi folks --
Has anyone out there run into, used, or generated digital data going
back
as far as, say, 1950 on the location of jobs? I'm interested in
sub-county
level data, at least municipalities (or MCDs), for as many metropolitan
areas and counties as possible.
Thanks in advance.

Follow members of the CTPP listserve:
Although this is not technically a CTPP issue, it is related. My
organization is trying to use the NJIT's new land use modeling software,
TELUM. We have spent a lot of time and effort putting together the data
inputs for this model, but cannot make it work reliably. So I am
querying my fellow MPO's and other transportation/land use modelers and
planners: has anybody had much luck with TELUM? For that matter, any
luck with TELUM's predecessors, DRAM and EMPAL?
I am trying to decide whether or not to continue using TELUM for our
upcoming transportation model. NJIT staff have been helpful, but they
are half a continent away and after two or three months of devoted
effort our model still crashes on calibration. I may have to scrap TELUM
and go back to conventional methods. I would appreciate any ideas, tips,
etc. Thanks!
