The time has come to acknowledge that walking will be an indispensable component of 21st-century transportation. Today's plans for urban and suburban growth envision walkways as a vital part of multi-modal transportation networks. Walking is great exercise and beneficial to health. Unlike cars, buses, trams and trains, walking consumes no fossil-fuel energy and leaves no carbon footprint. Equally important, walking can be a positive aesthetic experience.
The term "transit-oriented development" (TOD) paints an incomplete picture of state-of-the-art planning and urban design. The terminology should change, along with our mind-set. We should talk about and advocate multi-modal-transportation-oriented development.
