The conspicuity of routing signs was measured as the number of signs located in real-world scenes. Colour slides were used for stimulus presentation. A first series of experiments strongly suggested that the performance of the subjects depended on number, size, location and colour of advertisements in the environments where the routing signs were displayed. These aspects of the environments were not systematically varied, however. In a second series of experiments, advertisements systematically varying in number and size were added to a scene. The locating of routing signs deteriorated with increasing number and size of the advertisements.
