Data on national road network refers to:

• Road category - motorways, category I, II, III roads;
• Type of pavement - bituminized, cobblestones, crushed stones, coarse aggregate and unpaved roads.

· The classification of National roads is made by conditions and order set by the Council of Ministers;

· Glossary for transport statistics· Classification of Territorial Units for Statistical Purposes in Bulgaria - NUTS ;

· Glossary for transport statistics - - Geneva 2003.

The National road network (NRN) ensures the connections between the built-up areas in the country and those with other countries for transport of goods and passengers. National roads are classified according to their administrative and economic importance and functions for the transport system in the following classes: motorways and roads of the first, second and third class, which ensure national significance transport connections and give the length of the state road network. Separate national roads are included in the Trans-European road network.

According to road category NRN includes:

Motorways - roads designed exclusively for high-speed vehicular traffic.  

They have separate carriageways for traffic in each direction with a dividing strip between them, emergency stopping lane and crossing other roads or railroads at a different level. The maximum speed is 140 km / h.

 I-st category roads –designed for transit traffic on big distances /mainly from border to border/. They service big territories and coincide with the major transport fluxes in the country.

II-nd category roads - designed for transit traffic on medial distances. They have distributing functions and provide optimal routes for transit traffic to different country regions.

III-rd category roads - roads within the boundaries of built-up areas that are part from roads higher category. Ensure the connection between the different municipalities as well those to local roads.

According to type of pavement:

Bituminized road surface - for all types of traffic;

Cobblestones - often used for roads with major traffic;

Crushed stones - used for local roads with light traffic;

Coarse aggregate - used for local roads with very light traffic.

Unpaved roads. Usually these are forest, tractor and cart roads without a special coating.
