Does driving make you fat? Does taking transit make you thin? Are you likely to be healthier in a city with small blocks or big blocks? Are you less likely to get diabetes if you live near a park? Do you breathe more pollutants in heavy traffic on a bike or in a car? What urban form is healthier when you’re a teenager or a senior? Are you likely to have more friends if you live in a walkable neighborhood? What health-related economic benefits do you receive from walkability, bikeways, and greenways? How do you measure these things? One of the most cited scholars in the world, Dr. Lawrence Frank coined the term walkability and has been answering such questions for three decades. After sharing the state of the evidence linking built and natural environment features with health and economics, he and Yilun Zha discuss the findings’ impacts on cities and public health.

Like many downtowns, suburbanization wiped much of the life out of Greenville SC’s downtown by the 1970s. Today it is a thriving, award-winning destination largely due to the 30-year leadership of Mayor Knox White. Why has it been so successful and what can other cities learn from its multi-layered strategies to attract people downtown and celebrate gathering at new iconic parks (including removing a four-lane highway bridge to do so?) Mayor White explains and Michael Messner and Ellen Dunham-Jones lead the follow-up conversation on the implementation and impacts of this remarkable redesign.

Autonomous vehicles are here – but which mode best serves cities? Private AVs like Tesla? Privately-owned and operated robotaxis like Waymo? Or publicly supported on-demand AV shuttle buses? Are on-demand AV shuttles a more efficient way to provide transit service in lower-density areas where regular bus service is infeasible – and if so how should cities plan for them? This summer Boca Rotan, Florida began a three-year roll-out of AV shuttles. An affluent city struggling to attract service-industry workers, the city sees the shuttles as a means of connecting affordable housing to affordable transportation. Is it working? Jun Wang, Assistant Professor at FAU in Boca Rotan shares her dissertation research on planning for AV shuttles before Mark Wigder, Boca Raton Council Member tells us why he championed the AV shuttle and how it’s doing so far. Noted transit urbanist Peter Calthorpe also makes a surprise appearance.

How did Oklahoma City go from being one of America’s most obese and least walkable cities in 2008 to an award-winning thriving downtown attracting an influx of jobs, dining, recreation, and young adults? Through the implementation of a complete redesign of the public streets and parks in the 50-block downtown core. Defying fears of gridlock, the one-way street system and a third of the driving lanes were eliminated while on-street parking was doubled, a bike network established, and over 2,500 street trees planted. Then Mayor Mick Cornett and urban designer Jeff Speck discuss how they pulled this off and lessons learned.

Is it possible for a suburban community to invest in long-term amenities like a walkable downtown, a symphony hall and award-winning public spaces while reducing property taxes? Jim Brainard did just that - and more - during his 28 years as Mayor of Carmel, IN. His presentation shows how he freed up redevelopment opportunities by using Tax Increment Financing to build public parking and elevate design quality. In a follow-up conversation Ellen Dunham-Jones asks him to discuss the health, energy, and climate impacts of these changes - as well as his conversion of over 150 Carmel intersections into roundabouts. Listeners may want to visit the Redesigning Cities website to watch the video to see Jim’s slides.

As listeners and viewers to Redesigning Cities 40+ episodes should have figured out – urban design is complicated business! It requires integrating a wide range of social, transportation, energy, and environmental collaborators, infrastructures, networks, and design details into a spatial framework. Luckily Nico Larco, lead author of the Sustainable Urban Design Handbook talks us through this matrix of issues, as well as his research on emerging technologies and new mobility.

What roles do homeownership, the affordable housing crisis, and the law play in achieving the goals of Dr. Martin Luther King’s beloved community? Can housing design, land use policy, and activism overcome political and social barriers to enrich connectedness, neighboring, and belonging – especially today? Drawing on her extensive experience managing transformational change in both the for-profit and non-profit sectors, Natosha Reid Rice speaks to these challenges and shares lessons on how to leverage the power of proximity to curate thriving communities now.

Can Urban AI activate human agency in the performance and design of cities, particularly in relation to climate change? Can the unfair systems that produce climate vulnerability in the first place, expand the role of marginalized stakeholders in climate adaptation? Leading urban tech researcher, Dr. Anthony Townsend examines the role that artificial intelligence innovations could and are playing in empowering such communities. From resilience planning chatbots to synthetic visualizations of flood threats, he maps the possibilities and risks presented by these emerging technologies for the urgent work of responsible participatory climate adaptation. Debra Lam leads a follow-up conversation.
