Should Hallitube throughput be compared to highways or lightrail ?
Comparisons are complex, because the speed of highway lanes varies, both regionally and by lane position. Additionally, the de-congesting effect of a Hallitube project obviously varies with the number of congested lanes on the “competing” highway: the more there are, the smaller the effect of the tubes. In addition, in some areas of LA, only a single tube fits under the very narrow overpasses built in the 50’s, so there, a tube looks good as a lightrail alternative only. However, many national and international highways are two or three lane systems, often in mediums sized SMAs (standard metropolitan areas), and here a Hallitube-quad makes a massive difference in congestion. The critical point though is that a Quad system can convey its drivers faster, and closer to their neighborhood than a light rail system, and the money is spent largely in the US. Also, the cart portion of the system is extensible in case of “peak-oil” the widely feared quadrupling of the oil price in which we all
