This document compares two streets - Sejong-no Road in Seoul, Korea and Jalan Tuanku Abdul Rahman in Kuala Lumpur, Malaysia. It analyzes how the physical characteristics of each street, such as scale, layout and building types, influence human activity and interaction. Jalan Tuanku Abdul Rahman is a narrow shopping street lined with shophouses, which creates more opportunities for contact between pedestrians and shop owners in the covered walkways. In contrast, Sejong-no Road is a wide ceremonial street with large-scale buildings and open spaces that discourage casual interaction. The intensity of contact points differs based on the street design and what activities are held there.
