The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of transportation of existing art and more specifically relates to electric mass transit systems.
Current transportation systems offer significant freedom and autonomy but have severe drawbacks as well. For example, poor human driving causes most accidents, and gasoline engines create environmental damage. Most accidents occur on urban freeway ring roads and access roads, where traffic and right-of-way interactions have little oversight. A suitable solution is desired.
U.S. Pat. No. 4,361,202 to Michael Minovitch relates to an automated road transportation system. The described automated road transportation system includes a system for vehicular travel along a roadway. The roadway can be any hard surface that contains an embedded metallic guiderail along its center. A proximity transducer (metal detector) installed under the vehicle, senses the metallic guiderail and sends steering commands to the vehicle's steering actuators to keep the vehicle moving in the center of the roadway directly over the guiderail. Transponders are embedded along the guiderail at selected points for automatic roadway identification, position determination and automatic speed, headway and route selection and automatic traffic control. The system also provides automatic branching and lane changing. The vehicle's control system includes sensors, signal processors, a microprocessor and various power actuators that are connected to the vehicle's steering, braking and accelerator systems.
In view of the foregoing disadvantages inherent in the known electric mass transit system art, the present disclosure provides a novel pathway to a fully autonomous networked transportation system and method. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide an autonomous networked transportation system and method.
A flexible transportation system is disclosed herein. The transportation system may be useful to convey a user from an origin to a destination. The transportation system includes a network of enclosed passageways, roadway lanes passing though and networking within the passageways, vehicles able to pass along the roadway lanes within the passageways, and multiple passenger terminals dispersed along the passageways to effect boarding of passengers onto the vehicles. The passageways have an interior for containing the rails and vehicles, and an exterior. The vehicle has at least one induction motor for propulsion which engages the electromagnetic rail, a storage device electrically powering the motor, and a braking system able to decelerate the vehicle.
Vehicles will have at least one electric induction motors for propulsion and may periodically engage an electromagnetic rail. Blade turbines and regeneration braking charge the batteries that powering the wheel-based motors. Although braking occurs by slowing the motors and turning them inward, a separate emergency conventional breaking system may be added directly to the axles.
According to another embodiment, a method of transporting and networking passengers is also disclosed herein. The method of transporting and networking passengers includes providing the above-described transportation system, docking the vehicle at one of the passenger terminals, boarding the user from one of the passenger terminals into the vehicle, and driving the electric motor to propel the vehicle along the rail.
For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.
The figures which accompany the written portion of this specification illustrate embodiments and methods of use for the present disclosure, an autonomous networked transportation system and method, constructed and operative according to the teachings of the present disclosure.
The various embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.
As discussed above, embodiments of the present disclosure relate to an electric mass transit system and more particularly to an autonomous networked transportation system and method as used to improve the provision of a mass transit system.
Generally, a transportation system having advantageous features for efficiency, safety, and simplicity of operation is provided. The system is an autonomous transit system utilizing automatically controlled electric vehicles traveling in an enclosed passageway and accessed by restricted access roads. Each vehicle is in some form of electrical communication with a transportation network operation center. This minimizes the time and cost of transitioning to safe autonomous electric transportation. The system uses passageways having individual lanes to which the vehicles are restricted to. The vehicles may be constrained to lanes by governance of the transportation network operation center.
The system uses autonomous electric vehicles which may operate using the same near and opposite fast lanes and rights of way methods of existing urban freeway ring roads. They may utilize bridgework to access near side terminals which service restricted access lanes from local terminals. The vehicles may be constructed aerodynamically and utilize ram-air turbine generators, plasma actuators, regenerative breaking, solar panels and ion type batteries to power autonomous electric rotary motors and/or linear induction motors. Passageway systems may serve to “bundle” vehicles into control groups which operate as a single unit for safety. Vehicles may be lifted, accelerated, and stopped electromagnetically. Vehicles may be privately or collectively owned, operated, and used. No gears or transmission will be required. Brakes may operate conventionally or electromagnetically. Each passageway can feature curved floors, solar panels and vented walls built on the existing freeway lanes and rights of way and accessed form bridgework over middle and near lanes to near side terminals. The terminals may provide regional traffic control, maintenance and services for passengers arriving to and from Restricted Access Lanes. The passageways and terminals may be built with regulations in mind.

Preferably, the vehicles have wheels, each having a dedicated electric motor. Some embodiments may have axles to which the wheels are suspended. In such a case, each motor is directly mounted to an end of an axle. Alternatively, axle-less designs may be used. The electric motors may be mounted within and concentric to a hub assembly or the wheel itself. This structure enables the vehicles to be lightweight and eliminates complicated power transmission mechanisms. Additionally, each motor may be individually governed by the vehicle controller, providing adaptability to the vehicle's operation. For example, this governance may be advantageous for implementing differential functions, traction control, speed limitations, and other functionality.
In some embodiments, the vehicles may incorporate drive mechanisms having linear induction motors which interact with static or electromagnetic rails. The linear induction motors may be incorporated in tandem or in replacement of traditional electric motors.
