A method of multilevel vehicular traffic comprising the re-organizing of any road space into longitudinal, parallel, and adjacent main lanes ( 18 ) such that each main lane ( 18 ) comprises a middle sub-lane ( 14 ) and two narrow outer sub-lanes ( 16 ) so that one outer sub-lane ( 16 ) is on each side of middle sub-lane ( 14 ). Low cars ( 12 ) travel freely within the middle sub-lane ( 14 ) under high cars ( 10 ). High cars ( 10 ) travel freely within the outer sub-lanes ( 16 ) over and around low cars ( 12 ) and middle sub-lane 14 ). Both high cars ( 10 ) and low cars ( 12 ) move freely from one main lane ( 18 ) to another main lane ( 18 ) into respective outer sub-lanes ( 16 ) and middle sub-lanes ( 14 ). Such method substantially increases road capacity and thus significantly reduces vehicular traffic congestion at a fraction of the cost of multi-billion dollar road-expansion construction projects.
