Analyses of urban spaces have often stressed the importance of both the density and diversity of the people they attract. However, the diversity of people is a challenging concept to operationalize within the context of urban spaces, which is why many evaluations of urban space have relied primarily on density-based measures. We argue that a focus on only one of the two aspects misses important aspects of the variety of urban spaces in our cities. To address this, we design a methodology that evaluates both the density and diversity of human behavior in urban spaces based on geosocial media data. We operationalize density as the frequency of tweets from visitors to a particular location and diversity as the variety of the home neighborhoods of those visitors. Taking Singapore as a test case, we identify networks between the home neighborhoods of 28k Twitter users based on 2.2 million geolocated tweets collected between 2012 and 2016. Based on these data, we categorize the urban landscape of Singapore into four “performance” categories, namely High-Density/High-Diversity, High-Density/Low-Diversity, Low-Density/High-Diversity, and Low-Density/Low-Diversity. Our findings illustrate that this combined indicator provides useful nuance compared to differentiation between well and less performing spaces based on density alone. By enabling a categorization of urban spaces that fits closer to the diversity of human behavior in these spaces, human mobility data sets, such as the social media data we use, open the door to a practical evaluation of the design and planning of our heterogeneous urban environment.

Urban planning and transportation policies are vital to creating sustainable and liveable cities. Transit-orientated development (TOD) has emerged as a prominent approach that emphasises the establishment of neighbourhoods with convenient access to public transportation, thereby promoting car-free lifestyles. This research investigates the connection between proximity to transit stations and local living habits in Auckland, New Zealand, which is a car-dependent city aiming to transition to a sustainable TOD model. We use geolocational data from mobile phones to measure the daily mobility patterns of residents living within a 15 min walking distance of various transit stations. Employing ordinary least squares (OLS) regression, we analyse the correlation between residents’ average travel distances and individual mobility, considering different station contexts. We aim to determine whether individuals living near transit stations are more inclined to participate in local activities and make a higher proportion of short-distance trips. The results illustrate that approximately 54% of the residents show dominant localised mobility patterns. Living near a station is significantly associated with shorter annual travel distances, although this trend varies by area. Notably, only about 16 of the 34 stations studied indicate that their local residents predominantly engage in ‘local’ travel patterns. Rural stations show less correlation, likely due to poor infrastructure and limited walkability. This study underscores the vital role of proximity to transit stations in promoting sustainable mobility. It serves as a foundational guide for urban planners and designers to make informed decisions that improve the built environment and optimise land use.

As the urban development continues, different parts of a city can grow or decay by varying degrees due to natural deterioration or changes in governmental policies. City is the center for business, culture, and social activities; is the place that reflects geography, commerce, society, and culture context; is a complex whole that is woven by “people,” “activity,” and “space” “People” in the “space” can process “activities,” therefore, activities and space can influence each other. In this research, we aim to obtain insights on urban morphology by analyzing the changes in urban spaces’ “activity” patterns. We aim to explore the relationship between urban spatial configuration and functionality. Space syntax methodology is applied to investigate the urban spatial structure concurrently with the analytic hierarchy process method for evaluating experts’ survey responses to attain urban functionality index. Subsequently, the analytical data are compared and categorized to reveal the city districts’ spatial characteristics and their correlation. This research has proven that the analysis findings are consistent with the actual urban conditions, and thus affirms our analytical framework of having a creditable comprehension of the advantage and disadvantage of urban spatial integrations and its functionality. Therefore, our research methodology can be applied as an efficient preliminary evaluation tool for conceiving the merits of city districts. Based on the findings of our research, authorities will be able to discuss the urban development agendas in greater detail with higher efficiency.

Design guidelines and design review panel (DRPs) are crucial components in ensuring consistent and high-quality design within masterplan sites. This study focuses on New Zealand, examining the challenges faced by industry partners in adapting to master-planned design guidelines. The case study centres on Hobsonville Point, the largest government-led masterplan community in New Zealand, which promotes sustainable and higher-density living—an uncommon concept in the country. We conducted interviews with 18 key stakeholders involved in the development of Hobsonville Point. The results show that the DRP provides flexible judgments and insightful information that better accommodate individual development characteristics than the strict numerical standards specified in design guidelines. This study underscores the importance of the DRP in producing good design outcomes, especially when they are involved at the very beginning of the design process. Additionally, we took note of stakeholder concerns about DRP members’ expertise and the possible effects of high turnover rates on the design process. To strive for continual improvement, future empirical studies on the DRP process are encouraged to enhance proficiency and dependability. Design guidance should be prioritised to ensure that climate-related design is implemented to promote sustainable urban development.
