The document compares the streets of Petaling Street in Kuala Lumpur, Malaysia and Central Square in Cambridge, USA based on Jan Gehl's theory of social activities and contact points between people. Petaling Street is the cultural center of Chinatown but lacks spaces that encourage interaction, while Central Square is well-planned to support the local community through public spaces and transportation access that facilitate social contact. Differences in context like weather and culture impact the types of social activities and intensity of contacts in each location.
