11.0 Quality of Design and Construction:

11.1Redundant Systems:

In the same manner that an airliner must be capable of continuing flight in the event of a system malfunction, in order to avoid blocking the Grid a HPR compliant vehicle will incorporate several redundant measures which will enable HPR vehicles to reach the next exit should a system failure occur. During Phase I and II, while using the HPR System, Grid vehicles will run solely on electrical power using each individual electric motor on two or four wheels. Each motor will be individually connected to one, of two, electrical busses through typical fused circuitry. In the event of the failure of one electric motor a Grid vehicle will be capable of continuing under its own power to an exit on one or more of the operating electric motors although speeds may be greatly reduced. If a Grid vehicle has connected with a train of vehicles, and is not the last vehicle, it may be pushed by the vehicles behind it to an exit and even coast to a safe position.

11.2Power Loss:

In order to have a certain amount of "elasticity" in power transmission, an HPR vehicle will run off its own battery power during Grid operation, however, the Grid power system will charge batteries during transit. In the event that an HPR vehicles internal battery loses power altogether a Grid vehicle=s operator would have the option of diverting the DC voltage from the Grid Rail=s positive and negative connections directly to any of the electric motors in order to continue operation.

11.3On Board Electrical System Failure:

In the case of complete electrical failure, when sensors in the Grid=s central computer detect the malfunction and the disabled vehicle coasts to an exit, service personnel can be automatically notified and be standing ready to assist at the Grid exit. Entire HPR support cities may emerge at Grid exit locations.

11.4Two Way Communications:

A two way communications system will, in the same manner as aircraft communicate with Air Traffic Control facilities (ATC), provide HPR radio contact capability between a Grid vehicle and the HPR emergency control facilities. Standard cellular phones will be capable of communicating with Grid control facilities by way of circuitry contained within the Main Grid Rails.

11.5Tire Wear, Extreme Braking:

Since the amount of contact between a Grid vehicle=s tires and the Grid Rail will be controlled by hydraulic pressure, the amount of tire contact pressure may vary to provide the least amount of contact at which tire traction with the Grid Rail will be sufficient for propulsion. As the weight of the vehicle is completely situated on an HPR vehicles Thrust Plate the tires will be under little strain compared with regular street travel and tire failure is extremely unlikely while operating in Grid mode. In the event of tire depressurization or deformity of a tire, the hydraulic pressure forcing that particular tire against the Grid Rail would be released and the affected tire could be rotated outward and upward, away from the Grid Rail altogether until the vehicle could exit the Grid Rail.

11.6Improved Braking:

Braking action will be increased infinitely as the hydraulic pressure pushing the tires against the Grid Rail may be increased substantially in the event of emergency braking. 8 g deceleration is attainable.

11.7Wear Surfaces:

The major consideration in Grid dependability is the design and maintenance of a Grid vehicle=s Thrust Plate, failure of which could leave traffic along an entire Main Grid Rail, at a dead stop. High strength plastic friction strips which center a vehicle on the Grid rail in the event of a tire or electric motor failure must be monitored and inspected at regular intervals. To the extent possible, sensors will be installed to recognize a deteriorating condition of any necessary component of a Grid compliant vehicle.

11.8Construction and Maintenance Costs:

The Company believes that the HPR System can be constructed and maintained at approximately one half or less of the cost of building and maintaining a typical new highway based on the same number of vehicle transit miles.
