Introduction. The use of geographical spatial data of the public road network has led to the question of the feasibility of applying existing methods of road length accounting and the need to introduce single-lane road length accounting.
Problem statement. The search for alternative ways to account for the length of a road calls for improving the principles of forming road titles, which have certain solutions for accounting for sections with more than one lane in each direction and establishing the lengths of traffic interchanges, additional lanes on ascents, external and internal transitional high-speed lanes, dedicated (channelized) lanes, etc.
Objective. To improve the system of accounting for the length of public roads of national importance.
Materials and methods. The principles of road titling introduced in [1] have certain solutions for accounting for sections with more than 1 lane in each direction and establishing the lengths of traffic interchanges, which were rational at the time of adoption, but without further improvement may be ineffective and increasingly lead to contradictions. The need to introduce the term "length of a public road in single-lane calculation" is due to the fact that there are fundamental differences between the lengths of roads approved by the Resolution of the Cabinet of Ministers of Ukraine "On Approval of the List of Public Roads of National Importance" of December 15, 2023 No. 1318 [2] and the actual length (area) of lanes subject to repair and maintenance, since the road may have a different number of main lanes along its length, additional lanes on ascents, external and internal transitional high-speed lanes, dedicated (channelized) lanes, and exits may have several lanes in one direction.
Results. The article considers the issues of introducing a method for accounting for reducing the length of roads to a single-lane equivalent to establish the exact length of traffic interchanges, additional lanes, transitional high-speed lanes, etc. in order to determine the scope of work on new construction, reconstruction, repair and maintenance of roads. Based on the above principles of road length accounting and the data obtained as a result of works on determining the spatial coordinates of public roads of state importance, the lengths of public roads in single-lane calculation were calculated for international, national and regional public roads of state importance.
Conclusions. The implementation of the proposed method of accounting for reducing the length of roads to a single-lane equivalent allows to establish the exact length of traffic interchanges at the same and different levels, additional lanes, transitional high-speed lanes and provides a more accurate calculation of the volume of work for new construction, reconstruction, repair and maintenance of roads. This will contribute to the rational planning of public expenditures for new construction, reconstruction, repairs and operational maintenance of highways.
