Lithuania’s road network of national significance is sufficiently well developed (>21 thous. km) and over the past 10 years has been changing insignificantly. A major part (~64 %) of national roads has asphalt pavement, however, they are not safe. Even on the low-volume roads with the average annual daily traffic less than 10000 vehicles per day (vpd) under unfavorable driving conditions when driving at a speed of less than 70 km/h a large number of road accidents occurs. The low-volume roads are frequently unsafe, the driving conditions are bad and they do not serve their function, i. e. access. The work studies an important problem of the civil engineering science – factors, their influence on identifying which roads will be attributed to the group of low-volume roads, and the parameters of low-volume roads having the effect on traffic safety. The distribution of roads in country, parameters of low-volume roads influence on traffic safety will suppose further means and measures for the improvement of low-volume roads and the driving conditions.
