Application of a statistical analysis of traffic for the development of Lithuanian road network

For the purpose of making safe and convenient traffic road conditions Gravel Road Paving Projects have been implemented in Lithuania since 1998. According to the 1998-2000 Paving of Gravel Roads Program and 2001-2004 Investment Project of Lithuanian Roads (Gravel Roads) during 1998-2004, 1,5 thousand km of national and regional gravel roads have been paved. Gravel road selection for paving was based on traffic volume and by considering road conditions and road structure's material quality. Traffic is grouped as follows: low traffic volume, moderate traffic volume, high traffic volume and very high traffic volume. By referring to the data of statistical analysis, this paper presents the distribution and grouping of roads according to traffic. Based on this, the zoning of the Lithuanian territory has been carried out. Research data to improve traffic conditions and to solve regional roads problems through the use and implementation of the principles of sustainable development have also been investigated and summarized
