The AA Road Atlas comes in many sizes and scales, and in previous years I have generally recommended this one over the others - it is not the largest scale but 3.2 miles to the inch (2km to 1cm in readiness for metrication!) is enough for most people, and where it scores most is in the number of town and city plans. There are actually 87 of these, plus approach maps for London, Birmingham, Manchester and Newcastle, plus 30 air and sea ports, and the usual large scale Central London maps.
Some of the smaller town maps (eg Newquay, Weymouth Harbour) now appear as insets (over the sea) on the relevant map page rather than the section at the back.
There seems to be a bit of an obsession about speed camera sites. Fixed camera sites are shown on the map pages, and there are now so many that they threaten the clarity of the maps in some places, but they are not shown on the plans of town and city centres (which is where a lot of cameras are!). There is now an additional seven page section listing mobile camera sites, and this is in such small print on a coloured background that some people may need a magnifying glass to read it.
The new 6-page "jam-busting" map of the country, showing the main traffic and accident black spots, may be useful for journey planning, although since most of these are city centres and motorways it's a bit like stating the obvious. I found the symbols slightly confusing as well. Of better assistance is the list of motorway and major road restricted junctions.
Amazon's synopsis mentions the new distinction between narrow and wide minor roads, useful if going into the more remote areas. Ironically the showing of narrow A-roads, mostly in Scotland, is less than clear - you need to look very, very closely to see the hatched (rather than continuous) black line outside the red one.
So, overall, it's great for navigating through towns and cities, satisfactory for planning most journeys, but forget the speed camera symbols - we shouldn't really need them, should we?
