Abstract
Abstract A road traffic network wherein the fundamental "building block" is an endless loop of one way traffic flow, a second endless loop of one-way traffic flow completely surrounded by the first endless loop and having traffic flow opposite in direction to the traffic flow direction of the first loop and an interconnecting traffic flow roadway extending between the two loops. The interconnecting roadway merges the traffic seeking to transfer between the two loops such that no vehicle crossovers or intersections are encountered. A road traffic network can be made from a plurality of interconnected "building blocks" or traffic flow systems, each such system being interconnected with either a single two-way roadway or two one-way roadways which, again, allow vehicle transfers between portions of the systems without crossovers or intersections. Intraloop roadways are also provided such that a vehicle need not travel over the entirety of the endless loop if it is desired for the vehicle to transfer between a portion of a first endless loop and a second portion of the same endless loop. The intraloop bypasses or crossovers serve to allow vehicles to take shorter trips then would be required if the vehicles are required to travel over the entirety of the endless loop in order to arrive at an loop interconnecting roadway for transfer to the other loops of the network. An entire traffic flow system, i.e., city-wide or larger, can be developed by building and interconnecting the basic building block or traffic flow systems into networks which, too, are interconnected with one another.
