This channel would be suspended above the ground by arching pillars and posts that had a small footprint on the earth. They would be high enough so that the suspended coach could not hit anything beneath. In cities the channels could be attached to buildings many floors above the street. Because the coach would be so precisely steered by the channel an underground tube would be small and cheap to build.

The channel is made of pressed steel like an auto body, or even graphite or composite. Inside that channel, also protected from the elements. You would find an electrical power source.

You would find in the channel a means of telling location on the system accurate to millimeters. I would suggest a bar code system read by lasers.

It could be built in a factory and assembled on the route. I believe that this channel should be engineered so that every day people can participate in some of the assembly. They ought to be able to buy this pre built channel at someplace like Home Depot and assemble their driveway component of the system.

The motive assembly would be electric motors built of the lightest most efficient permanent magnets. Later on this system would be an ideal place to try some sort of magnetic levitation or linear motors Wheels are the best first choice.

Breaking would be dynamic and put power back into the electrical power system.

I would suggest that changing direction, or steering: that is diverting to a different channel would be directed by the computer that decided the route. The use of left turns should be minimized because they complicate the design of the traffic flow.

I believe that a constant flow of 35 mph in a city would easy to deal with. I believe that 130 mph would work for cross-country.

For the coach itself, again Lightweight is the watchword.

Some variation of aluminum tubing and fabric covering comes to mind. About six feet wide, ten feet long and six feet tall with a groove for the channel taking up the center portion. I believe that a total weight including passengers can be no more than 800 lbs.

In the passenger version the most important appointment should be a restroom, shower and the like. Only a few gallons of water should be carried and replenished by passing thru automated stations. Similarly wastewater would be dumped when passing over other stations.

The precision steering of the channel would allow the coach to glide millimeters away from a building door. The doors would open together as in an elevator.

This conveyance is going to be mechanically much simpler than an automobile and it would be simple to put sensors monitoring wear and calibration everywhere.

Individuals would own these coaches in the same way that automobiles are owned.

If one lived in a private home I believe that as the Moki Passage is first built the device might sit in what used to be the driveway. It might sit only a few inches above the earth. The channel would slope and the coach would move to that position very slowly. There would be sensors on the bottom to assure that there would be nothing trapped underneath.

Later on as building adapted it would be best if the Moki Passage would slide next to the wall of the house. And one leaving or arriving from a trip would never have to be exposed to the weather.

If one lived in an apartment this conveyance could leave a person at the most convenient spot and then travel on its own to a parking area.

This area could be some distance away.

The parking should be three-dimensional. And because of the lightness it would be very cheap and quick to build.

To travel from your site you would call the coach from its parking by a phone. You would punch in your numeric location. The computer on the coach would calculate the time that it would arrive at the spot where you could step aboard. You could then punch in the location of where you wanted to go.
