A system for transporting containers by means of heavy-duty vehicles (8a, 8b, 8c) which comprises at least one external heavy-duty vehicle and at least one internal heavy-duty vehicle (8a, 8b), a container store with a a plurality of storage areas and a plurality of storage aisles, and a separate operating area, wherein at least one first lane for the at least one external heavy-duty vehicle and at least one second lane for the at least one internal heavy-duty vehicle (8a, 8b) are reserved in the separate operating area, the heavy-duty vehicles (8a, 8b, 8c) can be operated together in a mixed mode traffic and the first and second lanes respectively lead through a transfer area of a handling device of a storage area and are respectively arranged here laterally of the storage area, characterized in that the lanes are physically separated from one another, at least in certain sections, by means of guiding elements, wherein the first and second lanes cross in first crossing areas of two storage aisles (L1-Ln, Q1-Qn), in which the guiding elements are arranged such that the first crossing areas are designed as pure crossover crossings, wherein the first and second lanes cross in second crossing areas of two storage aisles (L1-Ln, Q1-Qn), in which the guiding elements are arranged such that the second crossing areas are designed as turn crossings, wherein a plurality of guiding elements are installed in each first crossing area that is designed as a pure crossover crossing, the guiding elements extending up out of the road and thereby being given a chicane-like function, which forces heavy-duty vehicles (8a, 8b, 8c) entering the first crossing area into the desired lane and direction of travel, wherein in the first crossing area the guiding elements are dimensioned and arranged in relation to one another such that the storage aisles in the first crossing area are deliberately made so narrow that turning is not possible, but instead, for collision-free operation, the crossing storage aisle (L1-Ln, Q1-Qn) or lanes must be crossed over, wherein in each second crossing area that is designed as a turn crossing, turning into a specified one of a number of crossing lanes (L1-Ln, Q1-Qn) of the crossing storage aisle is possible and required for certain lanes and directions of travel, for which purpose a plurality of guiding elements are installed in the second crossing area. wherein the first and second lanes cross in first crossing areas of two storage aisles (L1-Ln, Q1-Qn), in which the guiding elements are arranged such that the first crossing areas are designed as pure crossover crossings, wherein the first and second lanes cross in second crossing areas of two storage aisles (L1-Ln, Q1-Qn), in which the guiding elements are arranged such that the second crossing areas are designed as turn crossings, wherein a plurality of guiding elements are installed in each first crossing area that is designed as a pure crossover crossing, the guiding elements extending up out of the road and thereby being given a chicane-like function, which forces heavy-duty vehicles (8a, 8b, 8c) entering the first crossing area into the desired lane and direction of travel, wherein in the first crossing area the guiding elements are dimensioned and arranged in relation to one another such that the storage aisles in the first crossing area are deliberately made so narrow that turning is not possible, but instead, for collision-free operation, the crossing storage aisle (L1-Ln, Q1-Qn) or lanes must be crossed over, wherein in each second crossing area that is designed as a turn crossing, turning into a specified one of a number of crossing lanes (L1-Ln, Q1-Qn) of the crossing storage aisle is possible and required for certain lanes and directions of travel, for which purpose a plurality of guiding elements are installed in the second crossing area.
