Bill, you are only half right. The 1998 Environment and Planning B paper
also published the data. Be warned - you need a magnifying glass to read
it...
By the way, is anyone aware of papers from other parts of the academic
community on pedestrian or vehicular movement that have published primary
datasets? A list could be useful for all researchers.

Subject: Re: Some of my concerns
Rui, what on earth are you talking about ? The two main sets of movement
data on the 1993 study are published in full detail within the paper - see
the map of the Kings Cross area on p 43 and the table for the City of London
on p 54.
The same could not be done for the 1998 paper as the data base was so large.
But we used some of this data for Shinichi's and my 2005 paper, and this is
now being made available to whoever wants it.
Of course Space Syntax Limited has to take care with its movement data base.
Nearly all of it is collected as part of commercial projects, many of them
highly sensitive. - Bill
I am very concerned with the fact that space syntax has not yet shared data
from studies published in 1993 and 1998. In particular, we do not have the
data used in
Hillier B et al (1993) - Natural movement (.), Environment & Planning B,
Vol. 19 38pp
I am also concerned with the suggestion that Space Syntax Lab is currently
sharing data at spacesyntax.org:
http://www.spacesyntax.org/datadownloads/index.asp
Let's go through the procedure that a user wanting to access the data would
have to follow:
First, users have to register.
Second, users have to agree with the 9 points in the terms and conditions:
http://www.spacesyntax.org/terms.htm
Third, users are told that "The verification process may take 2-3 weeks."
Points 6 to 9 of the terms and conditions make it impossible to work
independently on the data, as they forbid publication of findings without
prior permission of space syntax.
The research community has no interest in observations from 1999, or in
Ordnance Survey maps that may come with these. We were promised data from
the above study by Hillier et al. (1993) and from a study published in 1998.
All that is needed is the data in the format used in the studies published
in the literature, i.e. street names for the gates and their respective
counts -the maps are available in the original papers.
We are talking about data which is between 8 and 13 years old.
Why are we cutting through red tape to access it?
Why aren't the observations from Hillier et al. (1993) being shared for
independent scrutiny?
and why is this process taking years?
Kind regards,
Rui
