Spatial and descriptive data on the current reference system of state roads (RSDP) contain 3 classes of data:
1. Primary nodes RSDP - point entities with attributes:
• Node ID
• Node name
• The road mark to which the node belongs
• Type of node (reference system, section)
• Chainage of the node along the route of the state road to which the node belongs
• Mark of roads that intersect at the node
• Belonging to section
• GPS coordinates
2. RSDP primary sections - line entities with attributes:
• Link ID
• Direction (link direction indicates whether the link is intended for two-way traffic (O-
on both sides), for one-way traffic in the direction of chainage growth (D-right), for
one-way traffic in the opposite direction of chainage growth (L-left), or is a link in one of its
parts (section) intended for mutual traffic and on in the second part (section) there are
separate driving directions (M-mixed))
• Road category
• Road mark
• Start node ID and End node ID
• Name of start and name of end node
• Link length
• Initial and final chainage
• Direction of chainageing
• Comment (containing the following information: unbuilt traffic link,
folding traffic link, temporary traffic link, built but not exploited, etc.)
3. Traffic loops - line entities with attributes:
• ID, type and length of additional link
• Mark of the initial and final additional node
• RSDP node ID and name
• Road mark
• Date of recording the additional link
Loop data are collected successively. So far, three phases have been realized. Within phase
1 in 2020., 17 loops were recorded, within phase 2 another 19 were recorded loops at the
beginning of 2021., within phase 3, 30 loops were recorded at the end of 2021. year.
Loops are represented by additional links and additional nodes and have the prefix "d" in its
designation separates them from the primary sections and primary nodes RSDP.
