In order to produce a slab track for rail vehicles with an emergency pathway for road vehicles, a prefabricated track section with rails and sleepers is supported and positioned on a substructure by means of a supporting and aligning device. The method can include performing static analysis on code for a software environment to form an extended type graph. The shoulder straps criss-cross to form a soft, triangular shaped panel on the harness wearer’s back. The tear stitching is arranged on the protection device such that tension forces acting to rupture the tear stitching act primarily on the break point so that the tear stitching ruptures first at the break point and then along the first and second segments of the tear stitching. At least some of the plurality of participating vehicles are in direct communication with each other.
