Right, now have something workable.

Currently three data sources, two types - Route 66 TMC and BBC TPEG. The route 66 data needs more work as the lat/lon it gives are wrong at the moment.
Data is downloadable as XML or CSV. The CSV is the easiest format if you are looking to test the data by simply importing into MapPoint or similar.
Notes:
* This is a beta version so expect a couple of bugs if I haven't seen them yet
* I know the only usable data so far is the UK, but feel free to give me some more data sources that provide the right information, I'll have a go at parsing anything. If you can fix the Route 66 lat/lon, tell me.
* You'll see the URL for the route 66 data is not pointing at the route 66 server - this is because my hosting provider blocks connecting by the server to port 8080, so I've had to put a 'proxy' page in. The data is live.
* Type of incident is not implemented yet, it will be given time though, I've only had a few hours on and off during the day to write all this including the parser back end.
* Once again it's not finished, there are more feature to add obviously.
