The invention transforms conventional vehicles into Personal Road-Rail Vehicles (PRRVs) that have revolutionary dual mode of travel capabilities that permits their being driving as both conventional vehicles on conventional roads and as revolutionary high speed PRRVs on compact Road-Rail Highway Systems (RRHSs) (somewhat vaguely similar to a one car, high speed passenger train). it is envisioned these PRRVs and RRHSs will permit cost effectively upgrading and modernizing the national transportation system and infrastructure by : significantly reducing traffic congestion at major cities and highways by cost-effective adding additional multi-stacked, compact RRHS' lanes on existing real estate; expediting the transition to all electric PRRVs and the construction of electric power grids nationwide to support the embedded power grids in the RRHSs; and lastly by providing automated PRRV travel on RRHSs that will support evolving to fully automatic PRRV travel thus reducing the need for high speed passenger trains.
