Most mass transit systems move people in groups over scheduled routes. This has inherent inefficiencies for passengers; wastage of time by waiting for the next arrival, indirect routes to their destination, stopping for passengers with other destinations and often, confusing or inconsistent schedules. Slowing and accelerating large weights can undermine public transport's benefit to the environment while slowing other traffic. In this context, Personal Rapid Transit systems attempt to eliminate the inconsistency by moving small groups, nonstop, in automated vehicles on fixed tracks. A detail on comparison with the existing system with respect to new technology is briefed in the paper
