Paul credits architect Peter Calthorpe with originating the concept of transit-oriented development.
He writes, "In the past decade, however, Calthorpe's term has increasingly been co-opted by the real estate industry to market any kind of moderately dense, urban infill development. If the concept of transit oriented development is diluted to simply mean density and proximity to transit without discouraging car use -- or encouraging socio-economic diversity -- then we miss Calthorpe's message entirely. And in New York City, where transit is just about everywhere, simply branding development "transit-oriented" can render the term meaningless."
