This study aims to examine the gender gaps in the use of urban space in Seoul, Korea, to provide empirical evidence for urban planning for gender equality. We analyzed daily temporary populations that were estimated using mobile phone data. We used the total, women’s, and men’s temporary populations as well as the subtraction of the temporary population of men from that of women (SMW) as dependent variables. We first conducted a visual analysis on temporary population density using kernel density estimation and then conducted a further analysis using spatial autocorrelation indicators and spatial regression models. The results demonstrate that: (1) Temporary population patterns for women and men showed similarities in that both were larger in business areas than in residential areas, which means that a large number of women were engaged in economic activities like men; (2) the pattern for SMW showed the opposite, that is, women were more active in residential areas and areas where neighborhood retail shops, cultural facilities, parks, and department stores were easily accessible; and (3) both women’s temporary population and SMW had spatial autocorrelation and thus showed clustering patterns that can be helpful in urban planning for gender equality in Korea.

Though several studies have explored the ways in which people perceive the qualities of urban squares, the influence of living environments on such perceptions has received little attention. To fill this gap, this study examined differences in preferences for urban square design elements, particularly, the ratio of the width of a public space to the height of the surrounding buildings (D/H ratio), square size, and façade details, among people with different living environments. Virtual reality simulation techniques were used in controlled experiments with 100 participants of various nationalities, mostly Koreans, and conjoint analysis was applied to determine what combination of design elements most influenced urban square preferences. Participants experienced eight virtual squares designed with different combinations of the three design elements and assessed them based on five indicators of the quality of urban squares. Among the three design elements, the D/H ratio most significantly influenced the perceptions of quality, regardless of participants’ living environments. We conclude that the level of experience in various urban environments may affect people’s familiarity with these environments and their spatial perception and preferences. We thus suggest that socio-cultural differences related to users’ living environments should receive more attention in urban design practice. We also demonstrate that the emerging combination of immersive virtual reality technology and conjoint analysis can function as a useful tool for urban design research.
