General description:
This is the former system of the Soviet Union, which is still in use in Central Asia (Turkmenistan and Uzbekistan), though Uzbekistan seems to have introduced new numbers at least for administration, see orexca. In Russia the system has been changed but many numbers remain the same. Kazachstan has recently introduced its own system but the old numbers are still used.
M: M1 - M10 are main roads from/to Moscow (Moskva). Numbers evolve in counterclockwise order but 3 comes before 2, 6 before 5 (branching off 4) and 10 (to St. Petersburg) before 9. There is some clustering in other numbers.
A: There is some clustering within zones. Zone 1 covers Russia. Numbering begins near Moscow with A100 (parallel to the M1). Zone 2 used to comprise the Baltic states, Belarus, Moldova and Ukraine. None of these numbers are left. Zone 3 covered the Caucasus and Central Asia. The highest number is the A388 in Turkmenistan.
R: The name Republican highway refers to the republics of the Soviet Union. The 'R' is denoted as 'P' in cyrillic.

History: The current system was introduced around 1980. Before that, there were very few numbered roads (some Soviet republics only had one). Numbers were between 1 and 37. For more information see Russia. It can be expected that some of the countries will introduce new national systems.
E numbers have been extended to the Caucasus and Central Asia around 2000. In addition to an extension of the grid with odd numbers up to 127, 3-digit numbers with trailing zeroes E001-E016 were introduced. E001 and E002 are in the Caucasus and the rest in Central Asia. See Europe and E Route list.
