Abstract
The present invention relates generally to ground transportation systems, and more particularly to a fixed guideway transportation system that achieves a superior ratio of benefits per cost, is lower in net present cost and thus more easily justified for lower density corridors, and can provide passenger carrying capacities appropriate for higher density corridors serviced by mass rapid transit systems today. According to certain aspects, the present invention increases traffic densities by removing fixed obstacles such as track switches. In embodiments, this is achieved by providing vehicle-based switching mechanisms that interoperate with corresponding track structures to allow vehicles to switch tracks without any moving components on the track itself. According to further aspects, the invention provides a method of operating vehicle-based switching mechanisms that comply with safety requirements.
