At this second topic, a full list of the various categories of roads and paths is presented, along with detailed explanations.
a. Road Network
Motorways and National Roads.
11. Motorway with tolls. Asphalted “closed” road, ie the entry/exit is served only by interchanges. Nominal speed of 120-130 km/h.
12. Freeway without tolls. As above but without tolls (yet …).
13. National road with tolls. Asphalted road with 1-2 lanes in each direction, with double marking in the center. Entry and exit can be done with interchanges or junctions. Nominal speed of 80-100 km/h.
14. Highway without tolls. As above but without tolls. Nominal speed of 80-100km/h (actual 60-80 km/h).
20. Main regional network. Asphalted road with one lane in each direction and a continuous or intermittent service lane. Entry and exit from junctions or simple links. Nominal speed of 80 km/h (actual 60-80 km/h).
21. Main provincial network. Asphalted road with one lane in each direction (typically 8m large). Level Entries/Exits, many intersections with roads of lower categories, open to any kind of vehicle. Nominal speed of 60-80 km/h (actual 40-80km/h). It is the normal asphalt road who connects settlements and other key destinations.
22. Secondary asphalt network. Narrow (<6 m) road that serves secondary destinations. Actual speed 30-60 km/h.
23. Other paved roads. Narrow (<6m) road with some kind of cover (usually worn carpet road or cement). Actual speed 20-40 km / h.
25. Ramps of interchanges. Nominal speed of 40-80 km / h.
29. Under blacktop road. Wide road (it has of course the width of the finished asphalt), which is at an advanced or final stages of preparation before the blacktop. Can stay for a long time in this state and be eroded, but usually is an excellent unpaved road, which allows high speeds (up to 60 km/h) and soon to be coated. Passable even by large vehicles.
31. Main unpaved road which interconnects villages or branches of the main road network. Usually it is wide, has some structures (layer of gravels, stormwater culverts, bridges into streams) and maintains a good status throughout the year. As a dirt road, there can be local, spatially or temporally, problems (holes, mud after rain and snow in the winter, etc.). Almost any car can use it. Actual speed 30-60km/h.
41. Secondary road. Serves secondary destinations (farmland, woodland, beaches etc). It has either technical structures, or very stable substrate, and thus maintains a good patency throughout the year. This category may also present problems (potholes, mud after rain, snow, etc.) during winter. Any vehicle, but mostly a small car or a crossover, can use it. Actual speed 30-40 km / h.
42. Secondary dirt road of poor or changeable patency. Dirt road without any infrastructure, opened roughly at the ground, without stormwater structures, without bridges over the streams, which presents a variety of patency problems (puddles, mud, and erosion after the rain, deep tractor or jeep pomegranate, falling stones, pavement cross slope etc.). Most of the country’s dirt roads belongs to this category. Small cars can pass, but this category is the prime field of SUV. However, due to lack of infrastructure, a large proportion of these roads can be found in winter in a condition that would require at least an SUV with good tires or even better a thoroughbred 4X4. Actual speed 20-40 km/h.
50. Dirt road of very poor state, where only a 4X4 vehicle can pass. In winter, due to the snow, landslides, erosion or other problems, the road may be completely impassable. Classic category of Greek off-roaders’ game (some spend hours to tame 1 Km of unruly soil). Average speed 10-20 km / h.
60. Ruined dirt road impassable by car. In some cases a light dirt motorcycle may be able to pass. The road can be repaired in any unsuspected phase.
83. Secondary urban street pattern.
85. Urban pedestrian way.
61-63 Pedestrian way (outside urban areas). Paved pedestrian way, closed dirt road, permanently traces of mechanical interventions on the ground.
61. Pedestrian European or National Path(E4/E6, O2/O3 etc).
62. Marked pedestrian way.
63. Unmarked pedestrian way.
64-66 Cobbled path. The hiker’s joy.
64. European or National Path(E4/E6, O2/O3 etc).
65. With marks.
67-71 Clear dirt path. Typical mountain path or well used animal trail.
67. European or National Path (E4/E6, O2/O3 etc).
68. Important path with marks.
69. Secondary path with marks.
70. Important unmarked path.
71. Secondary unmarked path.
72-77 Difficult to identify, vague or intermittent path. Usually the case of out-of-use livestock trails.
72. European or National Path (E4/E6, O2/O3 etc).
73. Important pathway with marks.
74. Secondary path with marks.
75. Important unmarked path.
76. Secondary unmarked path.
77, 78 Route without a path but across a physical line (gully, ridge)
77. With marks.
