In 1992, the Albert Bridge was rewired and painted in an unusual colour scheme designed to make it more conspicuous in poor visibility, and avoid being damaged by ships.
Separating play areas from roadways, improved visibility at intersections, conspicuous stop signs, enhanced pavement markings and improved lighting prevent pedestrian injury.
Therefore, interventions focused on decreasing the intrinsic severity of crashes (e.g., reducing the speed limit for vehicles in urban areas, conspicuous stop signs or improved visibility at intersections) (DiMaggio et al. 2014) should be a priority.
Recommended interventions include those that are commonly part of SRTS projects, such as separating play areas from roadways, improved visibility at intersections, conspicuous stop signs, enhanced pavement markings, and improved lighting (Schuurman et al. 2009).
Males are more conspicuous than females, but reduce their visibility to predators by having camouflaged backs and restricting brighter signals to their sides, which makes them less visible to birds hunting from above while still being highly visible to mates and rivals on the ground.
This increased visibility is more than an exercise in conspicuous consumption: forced into servitude under colonial rule and later relegated to the margins of society, Bolivia's many indigenous peoples were long excluded from mainstream society.
Moreover, sexual signals may be more conspicuous on islands with shaded (darker) forest habitats to increase visibility to conspecifics, similarly to Anolis lizards (Leal and Fleishman 2004).
As mentioned previously, tags vary in their visibility; 'soft' tags tend to be inconspicuous and 'hard' tags conspicuous.
Conspicuous white speckles on the otherwise black vocal sac of Dendrobates pictus clearly increase the visibility of a calling male to the human observer in a highly structured environment (Hödl, 1991).
