Cool, this is quite a nice little script. Pity I have just upgraded to a car Stereo with bluetooth!

As an aside, I actually found that in my part of the world the highways agency rss feed (North East England) contains all of Yorkshire as well, and is too large an area with the vast bulk of the alerts being in Yorkshire.

The BBC local radio traffic RSS feeds may be a better alternative, they are for me, and my local one already has a twitter feed @tynesideroads.
