Transit-oriented development (TOD) refers to high-density, mixed-use development oriented around a transit station, where the development surrounding the station supports multi-modal movement (think: cars, busses, light rail, cyclists, pedestrians, etc.).
TOD supports a complementary mix of uses (residential, commercial, office) in a pedestrian-friendly environment. In other words, enabling safe and convenient travel between the transit station and final destination point(s) – retail, entertainment, employment, community services, and so on.
