Future Access to Essential Services in a Growing Smart City

The concept of accessibility – the ease with which people can reach places or opportunities –lies at the heart of what makes cities livable, workable and sustainable. As urban populations shift over time, predicting the changes to accessibility demand for services becomes crucial for responsible and ‘smart’ urban planning. The authors investigate how projected population change could affect accessibility to essential services in the fast-growing City of Surrey in Canada. They evaluated accessibility levels to healthcare facilities and schools across Surrey’s multimodal transport network using door-to-door travel-time measurements combined with high-resolution longitudinal census data. Paying close attention to two vulnerable population groups – children and youth (0–19 years of age) and seniors (65+ years of age) – the authors analyzed shifts in accessibility demand from 2016 to 2022. Results show that population growth both within and outside the catchments of existing facilities will have varying implications for future accessibility demand in different areas of the city. For instance, by 2022, the city’s hospitals will be accessible to ~9,000 more people within a predefined threshold of 30 minutes by public transport. Conversely, ~27,000 more people – almost half of them seniors – will not be able to access a hospital by 2022. Since low-income and senior residents moving into poorly connected areas tend to be more reliant on public transport, accessibility equity may decline in some rural communities. The authors' study highlights how open-source data and code can be leveraged to analyze accessibility demand across a city, which is key for ensuring inclusive and ‘smart’ urban investment strategies.
