This paper summarizes the evaluation of twelve city evacuation maps currently used in the United States for hurricane, fire, flooding or other scenarios requiring area evacuation. Each map is assessed by its use of components, graphic variables, and “general rules of legibility” as defined by Jacques Bertin in Semiology of Graphics (1983). Components include external and internal identification, level of organization, and length of components; variables include size, value, texture, color, orientation, and shape variation; and the general rules of legibility include graphic density, angular legibility and retinal legibility. The influential effect of mental health and physical stress will also be identified as key components in wayfinding design for urgent and emergency situations. The psychology of emergency ingress/egress and disaster psychology will provide a better understanding of decision-making challenges placed on people involved in distressed scenarios.
