To construct a system of rural roads needed insight into the relations between the extent of rural traffic and land use, the purpose of traffic movements, the period when it takes place and the kind of vehicles used.Rural traffic started and ended in land and farm buildings and may remain in the area or go beyond it. It may be part of farm operation or social traffic for maintenance of social relations between farmers and other people. Farm-bound traffic consisted of external functional traffic and social traffic.A linear relation was introduced relating annual average daily traffic volume (AADT) of internal functional traffic per 100 ha accessible grassland to density of land use, which was a function of the mean size of holdings. The mean working-day farm-bound traffic during October-March was highly correlated with the number of accessible farms.The effect was discussed of quality of roads and the length of routes on choice between an indirect route and a direct route in strip parcelled areas. The weighted length of the unmetalled parts of a route was approximately 2.5 to 3.5 times the absolute length.
