Produced by AIG and published by Transport for London, the Yellow Book tells the story of the Legible London prototype installed in the West End in November 2007, developed by AIG in association with Lacock Gullam for the London boroughs, TfL, the London Development Agency, London’s landowners and its travelling, resident and visiting public.

Development of the system involved tackling complex concepts and theories, such as map orientation and research into walking distances. The Yellow Book succeeds in telling the story in plain and compelling language, from the viewpoint of the users for whom the system is designed. The book is in two sections. The first half is an overview essay by Jim Davies outlining the background, research and development work that culminated in the installation of the prototype. The second half is a visual summation showing the application of theories, concepts and findings behind the system.

Documenting and storytelling, in books, movies and exhibitions, form an important part of AIG’s project approach, helping to inform the design process and gain public acceptance and support.

The Yellow Book won the 2009 Design Week Award for Best Promotional Brochure.
