Just spotted all the activity on this thread which is great to see. Personally I am reasonably neutral on what policy emerges from this conversation.
I do agree that few schemes are really really certain until the diggers arrive. By way of example, I personally removed the Longdendale bypass ( http://en.wikipedia.org/wiki/Longdendale_Bypass) from OSM a few years ago after the HA pulled out of the public inquiry when the inspector had rejected their traffic predictions for the seventh time! I do also agree that it is also far from certain that HS2 will be built whatever the administration is saying at present. I would therefore understand the view that nothing should be added as proposed until it is 99% certain that it will be constructed. By way of example it would be most remarkable if the A11 Fiveways scheme was not completed now that work has started. It would also be remarkable if Crossrail was not completed (but there is a bit more risk there). Some people however seem to believe that it is never appropriate to add content until construction has actually started for that bit of the infrastructure which seems a bit extreme. As people may know, I am very interested in understanding and modelling how our transport system is likely to develop and I if it is agreed that information about less certain schemes does not belong in OSM then we at ITO will devise a system to hold this information separately and allow people to contribute to it. We will combine it with OSM so that people can see what it might look like. You can see an example for the Norwich Northern Distributor Road (which is not in OSM btw) here: http://www.itoworld.com/map/245# Another approach would be to allow 'aspiration' as a tag prefix for roads that have considerable support but which do not yet meet the strict requirements for 'proposed'. Can I suggest that we work out what we believe are appropriate guidelines here and then get them discussion on an appropriate international list and also on the wiki?
