[OSM-talk] Road Length Statistics by county

[Peter Miller]

I notice that the Office of National Statistics publishes a document
detailing the total mileage of roads in each county in the UK.

http://www.statistics.gov.uk/STATBASE/Source.asp?vlnk=1255
<http://www.statistics.gov.uk/STATBASE/Source.asp?vlnk=1255&More=Y> &More=Y.

 

This document is evidently only available on paper, but the data clearly
exists and if we produced our own statistics from OSM data on a county by
county basis it would be possible to compare this with the official figures.
To achieve this we would need accurate county boundaries. Is this available
from OSM or from some creative commons source? If not then a UK university
would certainly have access to the right data and also the ability to do the
stats for us. I don't believe that that could possibly create IPR issues.

 

It might also be useful to be able to create an index of road/street names
for all the named roads within a defined area (a county / borough etc). This
could be used to firstly pick up typos, and then to manually cross reference
with a commercial data source. One would of course then need to re-survey
the streets in question to ensure that the differences were indeed our
problem and what we should have on our maps.

 

Would it also be usefully to create a list of road 'ref's' in a county,
starting with Motorways, 'A' roads, then 'B' roads and their length within
each county? This would again pick up typos, missing references and also
give a measure of completeness when compared to lists from other sources.

 

 

Regards,
