Evolving and Designing the 30-minute City


The 30-minute isochrone has long defined people’s use of cities, from ancient times, through the trams era, to modern times. Networks and land use co-evolve with technology subject to the constraints of available time. There are opportunities (low-hanging fruit) to use design to reduce the costs of travel. This talk discusses both the measurement of accessibility, why it matters, and how it might affect traveler behaviour, institutional behaviour, and public policy. Looking at data from rail and tram development in Sydney from the 1800s and Australia today, implications about the effects of accessibility are described.
