In the 1986 he, along with Sim Van der Ryn, published Sustainable Communities. In the early 1990s he developed the concept of Transit Oriented Development highlighted in. He has taught at U.C. Berkeley, the University of Washington, the University of Oregon, and the University of North Carolina. In 1989, he proposed the concept of Pedestrian Pocket, an up to pedestrian-friendly, transit-linked, mixed-use urban area with a park at its centre. The Pedestrian Pocket mixes low-rise high-density housing, commercial and retail uses. The concept had a number of similarities with Ebenezer Howard's Garden City and aimed to be an alternative to the then usual low-density residential suburban developments. As an expert on urban planning, Peter Calthorpe, is frequently cited in various reputable mass media including New York Times, The Guardian, National Geographic, Newsweek, Grist, Metropolismag, The Advocate and others. In 2006 Calthorpe won the ULI J.C. Nichols Prize for Visionaries in Urban Development. In his 2017 TED Talk Calthorpe addressed the necessity of efficient use of space and resources in the context of climate change and identified urban sprawl an urgent trend that requires immediate attention. In 2018 Calthorpe launched urban-planning software UrbanFootprint that should help fight sprawl allowing non-experts to model the impacts of different urban planning scenarios. Among most recent Calthorpe’s concerns are autonomous cars as potential reason for increased urban congestion and suburban sprawl. Unlike the advocates of self-driving cars who believe that they will lead to fewer cars and faster commutes, Calthorpe believes that the convenience of autonomous transport will only encourage more car trips. He suggests alternative plan to avoid congestion – autonomous rapid transit – fleets of self-driving vans in reserved lanes on main arteries.
