This paper outlines the development of audcomputer design environment that generates station ‘reference’udplans for analysis by designers at the project feasibility stage.udThe developed program uses the theoretical concept of shapeudgrammar, based upon principles of recognition andudreplacement of a particular shape to enable the generation ofudstation layouts. The developed novel shape grammar rulesudproduce multiple plans of accurately sized infrastructure fasterudthan by traditional means.udA finite set of station infrastructure elements and a finite set ofudconnection possibilities for them, directed by regulations andudthe logical processes of station usage, allows for increasinglyudcomplex composite shapes to be automatically produced, someudof which are credible station layouts at ‘reference’ block planudlevel.udThe proposed method of generating shape grammar plans isudaligned to London Underground standards, in particular to theudStation Planning Standards and Guidelines 5th edition (SPSG5ud2007) and the BS-7974 fire safety engineering process.udQuantitative testing is via existing evacuation modellingudsoftware.udThe prototype system, named SGEvac, has both the scope andudpotential for redevelopment to any other country’s designudlegislation.
