An open space connects different areas of a campus by an axial street, which may form a strong spatial structure in a campus. However, circulation space provides far more than transportation. Well planned circulation can control over- stimulation through minimizing exposure to noisiness and congestion. A long distance of similar topology could be tedious. Different functions implanted along the path would avoid monotony and boringness. A vibrant circulation line design should consider path form, variety and sequence (Figure 11).
