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!
