Route-finding is much easier as through-routes are shown, giving the user the equivalent of local knowledge of an area, ideal for any driver and a real time-saver when avoiding main road queues. Furthermore, one-way streets and restricted turns are shown on the whole central London area. A planning map shows main roads in and out of London. Postcode districts and boundaries are shown on both the main mapping and on a separate map. The index of streets and notable features is fully comprehensive and has been carefully designed to be easy to use and read. Hospitals, railway stations, schools, shopping centres, universities, industrial estates and other such features are highlighted in red; places of tourist interest are shown in blue. The index includes postcodes. There is a map for central London detailing over 50 theatres and cinemas and a special map shows the London Underground.
