Since revolutionising map design in 1933, Henry Beck’s iconic map of the London Underground has set the standard for the mapping of transport networks worldwide but is this template always a success?

That is the subject of a new exhibition, by Essex researcher Dr Maxwell Roberts, which opens at South Essex College on 26 Fenruary.

Underground Maps Unravelled: Explorations in Information Design explores the use of Beck’s basic design rules: replacing chaotic, twisting routes with straight lines, horizontal, vertical or diagonals at 45 degrees only. It also looks at whether today’s complex transport networks require fresh approaches.

Dr Roberts, of the Department of Psychology, presents a collection of his own work: maps that break all the rules, maps that are easier to use, maps that teach us about good design, maps that challenge our preconceptions, and maps that are just intended to be decorative.

With expertise in human reasoning and intelligence, Dr Roberts has been interested in graphic design and the presentation of wayfinding information for some years now. This exhibition follows the 2008 re-print of his book, Underground Maps After Beck which surveys the major changes made to the well-known map, and the reasoning and political background that led to them.

Underground Maps Unravelled will be at South Essex College, in Luker Road, Southend, until 9 March.

This event is open to the general public.
