Stimulating conversations in residential streets

Abstract

Residential streets show underutilised potential for social interaction, a key factor in counteracting rising problems of social fragmentation and loneliness in urban environments. However, a lack of empirical evidence regarding the effectiveness of urban design elements that contribute to social interaction presents a gap in both existing academic discourse and urban planning practices. This study aims to address that gap by examining to what extent prevailing urban design elements stimulate the start of conversations in residential streets. It employed a Stated Preference Experiment to examine the specific contribution of five elements: windows, sidewalks, benches, people, and trees. The results highlight a strong preference for trees and wide sidewalks in residential streets to stimulate conversations. In contrast, windows showed no significant effects. Heterogeneity in the data sample indicated nuanced effects for differences in gender and mobility patterns. This nuance was found for the presence of people and benches, where positive effects were only found for certain subgroups. These findings provide empirical evidence for urban planners and policymakers, supporting targeted and inclusive residential street design that effectively stimulates the start of conversations.
