City Know-hows
Older adults’ driving patterns reveal how the design of our neighbourhoods impacts mobility and independence in later life. This research highlights actionable insights for urban planners to design age-friendly communities by balancing transit access, land use diversity, and safe road networks.

Target audience
Urban planners, transportation policy makers, and age-friendly community advocates.
The problem
Older adults face unique challenges in maintaining their driving independence due to cognitive and physical changes. Built environment factors like road network design and transit accessibility can either enhance or hinder their ability to drive safely and efficiently.
What we did and why
We analyzed GPS driving data from 134 older adults in St. Louis, paired with Geographic Information Systems and machine learning techniques. Our goal was to understand how neighborhood characteristics—like land use diversity, transit accessibility, and road design—impact driving distances and trip types.
Our study’s contribution
We demonstrate the strong influence of neighborhood transit access and land use on driving behavior. We highlight thresholds where built environment factors significantly impact driving patterns and provide evidence for integrating age-friendly design into urban planning.
Impacts for city policy and practice
Urban planners should consider:

This study explores how urban playground design can either segregate or integrate children within the broader city fabric. By comparing Venice and Auckland, we illustrate how playgrounds in Venice encourage unstructured exploration, while those in Auckland limit engagement to isolated, structured zones. We propose strategies for urban design that foster inclusive and dynamic public spaces for children.
Transportation planners and transit authorities must gain a better understanding of the passenger and ridership experience for those specific demographics who frequently use their services. This understanding can inform future improvements and help transit authorities work towards Universal Design.
