    摘要: The present invention relates generally to ground transportation systems. According to certain aspects, the present invention includes systems and methods that provide a higher degree of precision and a greater coordination of vehicle movement than is possible in conventional systems. For example, a control system according to the invention is designed to enforce vehicle movement along a route to a position versus time trajectory. The control system includes control equipment on the vehicle that reports its location on the track every 0.5 seconds. The controlling computer in the station receives the report, and knowing where the vehicle should be and how fast it should be traveling at that point in time via a run definition table prepared for the route, calculates a position and velocity error, and then calculates and sends a tractive effort (force) adjustment command to the vehicle that attempts to reduce the position and velocity error.

    摘要: 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.

According to certain aspects, the present invention provides a methodology for limiting the rise in headway as the vehicle speed increases. This innovation further allows systems to achieve shorter time separations between vehicles traveling at high speeds, thus significantly improving the utility of fixed guideway infrastructure.

The invention provides an emergency braking control system and methodology that enables the implementation of related systems and methods that achieve safe headways at higher speeds than conventionally possible, while maintaining collision avoidance capabilities. In embodiments, vehicles are controlled from one or more stations with commands that are periodically sent from the station to the vehicle. For the control of emergency braking, this command contains a Safe to Proceed (STP) field that is intended and is required for the vehicle to withhold braking.
