How does transportation affordability vary between TODs, TADs, and other areas
Brenda Scheer Reid Ewing
Transit-oriented development, or TOD, could be the “poster child” for sustainable urban development. It concentrates land uses, including commercial and multi-family housing, near transit stations so as to reduce car dependency and increase ridership. The benefits are manifold; increased community health, positive economic impacts, less harm to the environment and potentially greater social equity.
But what about affordability? In exchange for all these benefits, do TOD residents spend more…

Toward Automating the Measurement of Urban Design Qualities Related to Walkability
S. Hassan Ameli
Streets are one of the most significant elements of urban spaces to accommodate public activity and provide access to numerous locations and services. Today, our cities face various challenges, including urban sprawl, air pollution, and obesity. To address some of these problems, cities and local governments consider land use planning and urban design to lower car dependency and promote walking and biking. Many studies have characterized the built environment in terms of D variables density,…
