The steady trend of aging has caused great concern on how cities should better accommodate the social needs of aged population. Older people in general have more leisure time than younger adults but are found highly constrained in daily travel. To examine the imbalance between travel demand and transport supply among older adults, this paper decomposes their daily travel into two categories (visits to non-ubiquitous and ubiquitous facilities) according to major characteristics of travel behaviors using Nanjing Household Travel Survey data. Multinominal logit (MNL) models are applied to exploit the effects of household and personal characteristics, trip characteristics, local supplies, and public transport services on travel mode choices. Results show that (i) travel demand and transport supply are highly unbalanced for most non-ubiquitous facilities, (ii) relative to younger adults, older adults travel further and highly rely on public transport to access non-ubiquitous facilities, (iii) providing more public transit services nearby non-ubiquitous facilities are more reliable to increase the accessibility of older adults than increasing the number of facilities. These results would help policy-makers better understand travel behaviors of older adults and develop strategies to accommodate their travel demand, especially from the perspective of facility network reorganization.

老龄化的稳定趋势引起了人们对城市如何更好地满足老年人口的社会需求的高度关注。一般来说，老年人比年轻人有更多的休闲时间，但在日常旅行中受到很大限制。为检验老年人出行需求与交通供给之间的不平衡，本文利用南京住户出行调查数据，根据出行行为的主要特征，将其日常出行分为两类（非泛在设施访问和泛在设施访问）。多项式 logit (MNL) 模型用于研究家庭和个人特征、出行特征、当地供应和公共交通服务对出行方式选择的影响。结果表明，（i）大多数非无处不在的设施的出行需求和交通供应高度不平衡，（ii）相对于年轻人，老年人出行更远，并且高度依赖公共交通来访问非无处不在的设施，（iii）提供与增加设施数量相比，在非无处不在的设施附近提供更多公共交通服务更可靠地增加老年人的可及性。这些结果将有助于政策制定者更好地了解老年人的旅行行为并制定策略来满足他们的旅行需求，特别是从设施网络重组的角度来看。(iii) 在非无处不在的设施附近提供更多的公共交通服务比增加设施的数量更可靠地增加老年人的可达性。这些结果将有助于政策制定者更好地了解老年人的旅行行为并制定策略来满足他们的旅行需求，特别是从设施网络重组的角度来看。(iii) 在非无处不在的设施附近提供更多的公共交通服务比增加设施的数量更可靠地增加老年人的可达性。这些结果将有助于政策制定者更好地了解老年人的旅行行为并制定策略来满足他们的旅行需求，特别是从设施网络重组的角度来看。
