This is an investigation, analysis and reflection on the discussion and propositions about sustainable urban mobility, specially, on subjects that imply or concern directly the Visual Perception. This investigation is inscribed within the propositions, strategies, instruments, laws, examples and suggestions given as a bibliography to the course "Mobility and Sustainable Planning" (Eng. Dr. J. Pozueta). A point of view that focuses in Visual Perception to analyze the mobility is used because it is a necessity for the sustainability philosophy to come up with concrete "arts", displays, signals, etc., that must be seen from a distance so that they may persuade a change in conducts and behavior. If these "arts" were not clear in their message and perception the objectives will not be accomplished.
