Abstract
In case it moves in the underground passage which became intricate in three dimensions, maintenance of the sign environment of a guidance display board or a guidance map influences the convenience of the whole underground passage. Then, by this research, the display information on a guidance display board is observed, and the system which supports construction of more intelligible sign environment is devised by changing display information. It thinks that action of a man and sign environment are in the state from emergence in an underground passage, and the simulation of the crowd in an underground passage is carried out using AL technology. The simulation is made into an evaluation function, and it carries out GA execution, using "the display information on a guidance display board" as a gene.
