Transportation system with increased capacity

Abstract

A transport system for providing increased capacity to move individuals and freight while still accommodating the individual needs of passengers and freight movers to travel to unique destinations. The transit system including a car including a set of switching wheels that are designed to engage with a set of switching rails, the switching wheels being moveable to selectively engage with the switching rails to either maintain the car on the track or switch the car off of the track. The car having to capability to travel on the relatively high-speed track and on a conventional surface street.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of the filing date of U.S. Provisional Patent Application Ser. No. 60 / 658,730 filed Mar. 4, 2005.FIELD OF THE INVENTION [0002] The present invention relates to transportation systems intended to reduce highway congestion and crowding, with flexibility and independent control of vehicles. BACKGROUND OF THE INVENTION [0003] Traffic congestion is a significant problem in the United States as well as in many countries throughout the world, costing many billions of dollars annually. Although some people have and will in the future alter their commuting preferences in view of the state of traffic congestion problems, there is limited willingness of many people to do so. While “telecommuting” may reduce some traffic, workers and freight inevitably will need to be transported from one location to another. The transportation system should be improved to meet the needs of today's society. [0004] Ground transpor...

AI Technical Summary

Benefits of technology

[0015] The reduced headways for the cars operating on the track require automatic controls accommodating enhanced forms of freight cars and passenger coaches. While the speed of the cars may be increased above the speed of typical highways and railways today, speed is not the critical factor of the system. Rather, capacity of cars and track is the critical factor that is improved.

[0016] The improved headway is achieved by use of a specialized track for the car to run upon. In one advantageous embodiment, the track is provided with two horizontal riding surfaces spaced for stability (8.5 feet to conform to highway rules), and two vertical guide walls against which ride horizontal wheels, to provide absolute directional control in all conditions. The track is advantageously provided with a switching mechanism that allows cars to enter and leave the track without any movement of the track itself. The ability of cars to enter and leave the main track without any movement of the track itself has provided for significant improvement in headway. It is the ability for any car to switch to any other track, or off or onto the track that creates a high capacity, high-speed network.

[0018] It is further contemplated that in another advantageous embodiment, the cars are 8½ ft wide, the normal maximum width for a vehicle on the road. The cars may, in one advantageous embodiment, be 50 feet or so long so as to accommodate a relatively large number of passengers, and may be even longer for freight applications. Cars may be provided double-ended, having two identical ends. The cars are further self-propelled and may use any form of engine that is suitable, such as for example, a combustion engine, electric, hybrid, fuel cell or the like. The cars operate bi-modally, on track most of the time, but on the ground as well and may be steered or operated from either end of the vehicle. For example, it is helpful for a passenger coach to extend its range somewhat beyond the track station, such as to an office building or an airline terminal or special venue. For freight applications, it is highly desirable for the freight car to reach the factory door, the distribution dock, the produce field, etc. thereby eliminating the need to transfer the freight to yet another transporting vehicle.

Problems solved by technology

Traffic congestion is a significant problem in the United States as well as in many countries throughout the world, costing many billions of dollars annually.

Although some people have and will in the future alter their commuting preferences in view of the state of traffic congestion problems, there is limited willingness of many people to do so.

While “telecommuting” may reduce some traffic, workers and freight inevitably will need to be transported from one location to another.

At this throughput level, any disturbance causes a severe disruption in traffic flow.

Such disturbances may include traffic incidents (even in the opposite lanes), a driver slowing down, something taking away the drivers' attention and, in any case, an increase in traffic volume feeding in from other roads.

Railroads have specific drawbacks, namely, they do not typically go where individual passengers or freight businesses want to go.

Such additional transportation can be expensive and time-consuming; this is especially the case for freight businesses.

As a result, the railroads have lost freight business to trucking, and passenger traffic to automobiles.

Furthermore, obtaining right-of-ways to build new roads or even widen existing roads is a difficult and sometimes, almost an impossible task.
