Automated Guideway Transit

Automated guideway transit (AGT) is a fully automated, driverless, grade-separated transit system in which vehicles are automatically guided along a "guideway". The vehicles are often rubber tired, but other systems including steel wheels, air cushion and maglev systems have also been used in experiments. The guideway normally provides both physical support, like a road, as well as the guidance. In the case of fixed-route systems, the two are often the same in the same way that a rail line provides both support and guidance for a train. For systems with multiple routes, most AGT systems use smaller wheels riding on the guideway to steer the vehicle using conventional steering arrangements like those on a car.

AGT covers a wide variety of systems, from limited people mover systems, like those commonly found at airports, to more complex mass transit systems like the Vancouver SkyTrain. In the people mover role the term "automated people mover" (APM) is sometimes used, although this distinction is relatively rare because most people movers are automated. Larger systems span a variety of conceptual designs, from traditional subway-like systems to smaller car-like vehicles known as personal rapid transit (PRT) which offer direct point-to-point travel along a switched network. Between the two are larger vehicles sized for around 20 passengers, sometimes known as group rapid transit (GRT), which blend features of the PRTs and larger systems.

Famous quotes containing the words transit and/or automated:

    We only seem to learn from Life that Life doesn’t matter so much as it seemed to do—it’s not so burningly important, after all, what happens. We crawl, like blinking sea-creatures, out of the Ocean onto a spur of rock, we creep over the promontory bewildered and dazzled and hurting ourselves, then we drop in the ocean on the other side: and the little transit doesn’t matter so much.
    —D.H. (David Herbert)

    Nature is a self-made machine, more perfectly automated than any automated machine. To create something in the image of nature is to create a machine, and it was by learning the inner working of nature that man became a builder of machines.
    Eric Hoffer (1902–1983)
