The third requirement in circulation design is that points of converging traffic must be expressed, specially to indicate the facilities for rapid exits. The fourth requirement is that changes in level must be clearly expressed.

3. What are the three examples (names of buildings) mentioned by Prof. Watanabe to illustrate different horizontal circulation patterns?

Prof. Watanabe mention three examples to illustrate different horizontal circulation patterns, the first one is Pennsylvania Station in New York, because it is an excellent example of a spacious, broad and direct circulation. 

The second example is Centrosoyus Building in Moscow of Le Corbusier, because the circulation patterns are vague and signs or direction marks would be necessary to indicate whether one should go.
