Activity space (AS) is a measure of spatial behavior used to summarize the mobility behavior of individuals. Current studies often highlight the fact that AS is highly complex and multidimensional in character. Therefore, the need for more holistic approaches providing more comprehensive descriptions of mobility patterns is evident. This article assesses the activity spaces of young adults aged 25–40 living in the Helsinki metropolitan area using a dataset collected with an online map survey. Using a wide range of measurements covering different aspects of AS, we identified seven components that define activity spaces, namely size, intensity of activities, volume of trips, exteriority, polycentricity, elongation, and destination specialization. We then used the components together with travel mode use to identify a typology of daily mobility patterns. The results show that individuals with different types of AS differ significantly in their socio-demographic characteristics, such as age, gender, employment, household characteristics, and residential neighborhood. Furthermore, the study reveals interesting associations between AS characteristics and different aspects of wellbeing. Overall, the results highlight the importance of multidimensional and comprehensive approaches to understanding daily mobility of urban residents.

超越活动空间的几何形状：对赫尔辛基都会区日常出行方式，个人特征和感知幸福感的整体研究

活动空间（AS）是对空间行为的一种度量，用于总结个人的流动性行为。当前的研究经常强调以下事实：AS具有高度复杂性和多维性。因此，显然需要更全面的方法来提供对移动性模式的更全面描述。本文使用在线地图调查收集的数据集，评估了居住在赫尔辛基都会区的25至40岁年轻人的活动空间。我们使用涵盖AS各个方面的广泛度量，确定了七个定义活动空间的组件，即活动的大小，活动强度，行程量，外部性，多中心性，延伸性和目的地专业化。然后，我们将这些组件与出行模式一起使用，以识别日常出行方式的类型。结果表明，患有不同类型AS的个体在社会人口统计学特征（例如年龄，性别，就业，家庭特征和居住社区）上存在显着差异。此外，研究揭示了AS特征与幸福感不同方面之间的有趣关联。总体而言，结果突出了多维和综合方法对理解城市居民日常流动性的重要性。这项研究揭示了AS特征与幸福感不同方面之间的有趣关联。总体而言，结果突出了多维和综合方法对理解城市居民日常流动性的重要性。这项研究揭示了AS特征与幸福感不同方面之间的有趣关联。总体而言，结果突出了多维和综合方法对理解城市居民日常流动性的重要性。
