This study identifies the relationship between individual's travel and their perceived Quality of Life (QoL). We consider two variables for travel reflecting its objective/quantitative and subjective dimensions. The observed one is a measure based on public transport trip frequency and travel duration obtained from smart card data. The second is the perceived level of Travel Satisfaction which is obtained by survey data. This study is conducted in Shizuoka city, a mid-size city in Japan where we could obtain and link both data sets. We focus particularly on aging effects and therefore divide the data samples into three groups, non-elderly (less than 65 year), younger-old (65–74 years), and older-old (over 75 years). Older people show in general higher travel satisfaction. Regression analysis with travel satisfaction as dependent variable indicate the importance of travel opportunity for older-old. We then identify the relative importance of mobility on QoL considering both objective and subjective one and discuss transport policy implications for an aging society based on these results. The results provide support that public transport systems are determinants of its usage, travel satisfaction and eventually QoL. These relationships are most evident for younger-old but less significant for older-old.

公共交通旅行和旅行满意度对老年人生活质量的综合影响

这项研究确定了个人旅行与其感知生活质量(QoL)之间的关系。我们考虑旅行的两个变量,以反映其客观/定量和主观维度。观察到的一项措施是根据从智能卡数据获得的公共交通出行频率和出行时间进行的。第二是旅行满意度的感知水平通过调查数据获得。这项研究在日本中型城市静冈市进行,我们可以获取和链接这两个数据集。我们特别关注衰老的影响,因此将数据样本分为三组,即非老年人(小于65岁),年龄较小(65-74岁)和年龄较大(75岁以上)。老年人总体上对旅行的满意度较高。以旅行满意度为因变量的回归分析表明,高龄人士旅行机会的重要性。然后,我们基于客观和主观因素,确定了交通运输对生活质量的相对重要性,并根据这些结果讨论了交通政策对老龄化社会的影响。结果为公共交通系统的使用,旅行满意度以及最终的生活质量提供了支持。
