I think this is also adopted by Buckinghamshire.  For example, there is a 
four way junction where TWY/16/2, TWY/16/3, TWY/19/1 and TWY/19/2 meet. 
Oxfordshire don't do this. One of their four way junctions has the meeting 
of 265/29, 265/29, 265/33 and 265/33.

A web application I'm developing straddles many counties.  So I've decided 
to adopt the scheme:
    code-for-council:code-for-path-adopted-by-council
Examples are:
    BM:TWY/16/2
    BM:TWY/19/1
    ON:265/29
    ON:265/33

For the code-for-council (e.g., BM and ON), I've chosen to use the two 
letter codes that are used by the OS Opendata 1:50 000 Scale Gazetteer 
that is described at: 
http://www.ordnancesurvey.co.uk/oswebsite/products/50k-gazetteer/index.html
It's in field 12 of their colon-separated file.  There are 208 values.

Is this sensible?
