The Murdoch University ISTP team, led by Jeff Kenworthy and Peter Newman
did start to collect some of this data and we published a small amount in
on or two papers. Unfortunately, it soon became clear that this item of
data was difficult to get on a consistent basis. So there is no
comprehensive set of road ration data to my knowledge.

This question came up last year on the utsg list (and here on
sustran-discuss). The person who asked the question (Stephen Marshall) made
a summary of the replies available to anyone who wanted it. It is a useful
document. It is a 60 Kb file in Word 6 format and I now have a copy from
Stephen. If anyone wants it then please email me off-list and I will send
it to you. If you can't handle Word 6.0 then let me know and I will send it
as text only.

Best,
Paul.
