The CityTram vehicles are completely self-driving. In fact the cars themselves are passive. They are moved along the rails by a pusher system, much like goods are moved along an assembly line conveyor in an automated factory. A centralized computer controls the whole system and "drives" the car. This not only eliminates the labor costs associated with transit drivers, but it also assures access to all. No driver’s license is needed, so children, the elderly, the disabled, foreign visitors, and those at risk for a DUI can commute just as easily as anyone else. Because the system is centrally controlled and computer controlled, rather than controlled by a distributed group of human operators possessing varying levels of skill, it can be much safer. Also because the system is controlled by computer rather than humans, reaction times are faster. This allows the system to be more efficient and entry controlled, and so congestion is avoided even in high demand situations.
This central computer control is much more akin to today’s industrial automation systems that keep assembly lines flowing in a factory, rather than something like Google’s autonomous vehicle that attempt to replace the distributed human control. Mass deployment of self-driving cars is still 20 years in the future. CityTram’s separated grade creates a closed environment that is protected from the types of random intrusions and interactions that complicate autonomous control. Therefore the sophistication of sensory input and processing intelligence is far more modest for CityTram’s type of industrial automation. Just think of our city as our factory, and the people moving through it as the products moving between work-stations in the factory, and you can see that we already know how to do this safely and reliably, and inexpensively. People mover systems at airports around the world have been doing this task safely for years. CityTram’s proprietary constant motion control makes extending this type of control to 2D networks relatively simple.
