In this picture the data on the signs are misleading or skewed to the viewer and it does not tell the audience what exactly to do at this area or place. The designer was overly concerned with designing a visual compelling graphic which is why there is misleading design solutions. It would be impossible to understand the context the designer of the signs is trying to get across therefore making these signs ineffective information. You can not have both signs up there must be one or the other to not mislead people.
