Barriers

Barrier style indicates something specific; in this photo these are temporary barriers, so they are moveable items. The red and white style of broken paint-work is seen on items that suggest danger ahead, and where caution is needed. It may relate to the way in which society is taught to see the colour red as a danger or stop signal, or it may also be for reasons of visibility. The barriers are high enough to indicate that they should not be climbed, however, they are not solid and they do allow for people to get between the top and bottom should they so choose, although this is never deemed proper in society, and people will normally only ever comply by walking around the area; the white arrow on the blue circular background is a road sign but it is directed to the attention of pedestrians, since it is the pedestrian who is being directed to walk around, and not therefore meant for the purpose of instructing a motorist. In a way, it could be argued that the arrow sign is both irrelevant and superfluous, because the barrier makes it obvious that a pedestrian must walk around, in which case authority is being enforced here; and society is being informed as to what to do, even though common sense will dictate that they would have gone around the barriers anyway.
