This study analyzed the relationship between street typology and human behavior activities in Kelurahan Kapuk of West Jakarta. The study employed mixed qualitative methods of interviews, mapping, and observation of 85 houses and 1142 activities.The survey found that although different street typologies exist, the main influencing factor for street based human activities relates to physical amenities, social-cultural practices and the width of the street/alley. The paper suggests that minor land adjustment through re-blocking with lots, widening of some cul-de-sacs to improve street layout and provision of elderly friendly open spaces is necessary to improve the physical environment of Kampong.
