This title features clear mapping, use of colour and a clear road hierarchy. It uses the most up-to-date digital data from Ordnance Survey and the AA. The maps highlight 24-hour petrol stations, AA service centres, recommended restaurants, pubs and hotels. The congetion charging zone is also included. Clever use of colour means that the atlas can be read under street lighting, while a battleship grid should make for easier referencing. Details such as one-way streets are clearly marked.
