Being socially connected is critical for later life. As travel is essential for most social interactions, older adults can better engage in social activities and maintain supportive social relationships by increasing public transport use. In transit-oriented cities such as Hong Kong, older people benefit from the well-developed transport system – they can still maintain high mobility rates in their later lives. However, there is a mismatch between metro development and the travel needs of older people. Their favourite travel, the public bus, has been continuedly reduced or adjusted with the expansion of the metro system. This may discourage them from staying active, connected and healthy.
