B) Citywide, 3D SkyTran Grids
This second example compares the 28
mile long light rail system recently proposed for Orange County
California to a SkyTran three dimensional 1 by 1 mile grid system
that completely covers all cities in that county.

*Conclusion:
For less investment capital than required to build a
short 28 miles of elevated light rail, we can
install a county-wide SkyTran grid system (1,072
miles worth). The benefits are 40 times the
hourly passenger carrying capacity, usefulness to everyone
in Orange County, greatly reduced commute times and
anet income to the County instead of a
continual drain of the taxpayer for subsidies.
Furthermore, there are huge additional multiyear
State and Federal savings because of the resulting
diminished need for new roads and highways.
**Same comments as for case A. |
As already proven with
automobile intelligent highway following systems tests in San Diego,
California, super fast computer sensing and control allows safe
close headway spacing (much closer than if humans are the sensor and
control response units). This technology allows each SkyTran
bi-directional line to have the carrying capacity of a six lane
freeway (three lanes in each direction).
The benefits of this capacity combined with low costs per mile
can easily be envisioned. Imagine how automobile congestion would be
relieved if we could afford to build parallel freeways 1 mile to the
right and 1mile to the left of every existing freeway. Then, another
set at 2 miles to the right and 2 miles to the left, then 3 miles,
etc. Then, wherever the new freeways crossed an old or new freeway a
3 dimensional cloverleaf overpass system would be constructed.
Affordable
3D Freeways = Enormous Capacity: In fairly short
order, drivers would find the "old" freeways no longer
heavily congested because other drivers were smart enough to figure
out that better, more direct, personally useful routing now existed
between home and work. No longer would all the traffic have to
be funneled into just a few freeways. Unlike paved roads, a
multitude of SkyTran "3D freeways" and "3D cloverleaf
overpasses" is affordable. The SkyTran result is an enormous
commuter carrying capacity!
