Good morning, everyone. Today we'll continue our discussion on urban planning. One key concept is the '15-minute city', where residents can access most daily necessities within a 15-minute walk or bike ride from home. This includes grocery stores, schools, parks, and healthcare facilities. However, a recent study in Melbourne found that while this model works well in dense inner suburbs, it faces challenges in outer areas with lower population density. For example, in these areas, public transport connections are often infrequent, making it difficult for residents to reach services without a car. The researchers suggest that planners should focus on improving transport links rather than just adding local shops.
