Objective The aim of this study was to examine the spatial accessibility of the aged and older adult population of the greater Sydney region to the bus public transport network, and the proximity of this transportation route to public and private dental services. Methods This study used geographic information systems (GIS) to examine, at a population level, the spatial accessibility of the public transport network and dental provider locations. The prime focus of the present study was on the aging population residing within 50 km of the General Post Office of metropolitan Sydney. Retirees (aged ≥65 years) and older adults (aged ≥85 years) were the two subsets of the aging population. Results Sydney’s bus network is currently supplying bus transport to both older and disadvantaged groups, facilitating the needs of more than half a million older people. Regardless of socioeconomic status, 12% of the entire population, 11.5% of retirees and 10.8% of older adults resided 500 m away from accessible medium-frequency bus stops. Approximately 40% of the overall population consisted of people of lower socioeconomic status living within 500 m of a medium-frequency bus stop, whereas 60% of the population were of a high socioeconomic status and lived within 500 m of a medium-frequency bus stop. Conclusion Metropolitan Sydney has a transport system that is substantial and robust, and appears to offer relatively similar spatial accessibility for all socioeconomic groups. This system is an example of great urban planning, where the distribution of bus stops is evenly positioned in both high-density areas and areas of low socioeconomic status. What is known about the topic? Older adults and disadvantaged people suffer from higher levels of dental disease compared with the rest of the population. Older adults and disadvantaged people are more likely to rely on public transport to access healthcare services, including dental care. The Australian population is aging rapidly. What does this paper add? Although a previous study examined the accessibility to services via the train network, this is the first analysis of the spatial accessibility to dental services via the bus network in Sydney. Most older adults and disadvantaged people in Sydney enjoy acceptable spatial access to the public transport network, and thereby to dental practices. Urban planning, in terms of determining healthcare service locations and the public transport network, needs to consider the distribution of older adults and disadvantaged populations. What are the implications for practitioners? Practitioners are more likely to attract older adult patients to their practices or clinics if these are located within easy access to the public transport network.

To mitigate car traffic problems, the United Nations Human Settlements Programme (UN-Habitat) issued a document that provides guidelines for sustainable development and the promotion of public transport. The efficiency of the policies and strategies needs to be evaluated to improve the performance of public transportation networks. To assess the performance of a public transport network, it is first necessary to select evaluation criteria. Based on existing indicators, this research proposes a public transport criteria matrix that includes the basic public transport infrastructure level, public transport service level, economic benefit level, and sustainable development level. A public transport criteria matrix AHP model is established to assess the performance of public transport networks. The established model selects appropriate evaluation criteria based on existing performance standards. It is applied to study the Stonnington, Bayswater, and Cockburn public transport network, representing a series of land use and transport policy backgrounds. The local public transport authorities can apply the established transport criteria matrix AHP model to monitor the performance of a public transport network and provide guidance for its improvement.

Global aging has raised increasing concerns on the health and well-being of older adults. Public transport is a viable option to improve the mobility and quality of life among older adults. However, policies that promote the public transport use among older adults are rare. This study utilizes the eXtreme Gradient Boosting (XGBoost) decision tree to explore the non-linear associations of the built and social environment with bus use among older adults in China. The bus use of older adults was obtained from the Zhongshan Household Travel Survey (ZHTS) in 2012. Results show that non-linear relationships exist among all built environment and social environment characteristics. Within certain thresholds, the percentage of green space land use, land use mixture, bus-stop density, and dwelling unit density are positively related to bus use among older adults. Likewise, one social environment variable, the proportion of older adults in a neighborhood, is the key social environment variable. Furthermore, the dwelling unit density and proportion of older adults appear to have an inverse U-shaped relationship. Additionally, age, ownership of motorcycles, and distance from home to the nearest bus stop also show non-linearity. The findings presented in this paper facilitate effective planning interventions to promote bus use among older adults.
