Track sections

Lines representing each section of the tracks. A section has at least one lane. A section belongs to a municipality. A section represents, most often, the center of the roadway. The sections of track are topological: the ends of a section correspond to intersections or junctions, except in the case of overlap (see next paragraph). In the case of a bridge (crossing of a road or rail section): the sections intersect without cutting each other. A stretch begins at an intersection or junction and ends at another intersection or junction
