The study of influence, exerted by the road projects on road traffic safety was carried out on the basis of data, contained in the System of Registry of Accidents and Collisions (Polish acronym: SEWIK) for the years 2006-2012, and the questionnaire-based survey. The level of safety on the motorways and expressways, or, more broadly – on the separate traffic roads, is being assessed as much higher than on the remaining national roads. Construction of a motorway results in a significant drop in the number of persons harmed in the accidents over the connections between the cities considered. The fast traffic roads, including the ring roads, being the segments of expressways, significantly improve the safety over the routes of national roads, but do not entail any important change in the accident rates on other roads.
