Tymoshchuk O. Improving the passport system of roads at the operation stage

The dissertation is devoted to the developed scientifically substantiated approach on definition of rational quantity of technical indicators for improvement of structure of the passport for highways of the state and local value. Currently, inconsistencies in the informatization of road network management processes have led to the emergence of a large number of data collection methods and the presence of separate software-analytical systems (PAC) that store such data and there is no single approach to assessing the quality of collected data. and the effectiveness of the use of information obtained. In accordance with the identified areas of research, an analysis of existing methods and technologies of data collection currently used in the road industry and the feasibility of their use in the certification of roads. On the basis of the conducted theoretical and analytical researches the economic-mathematical model with use of approaches of qualimetry that allows to insert in the final stage numerically ranks of technical indicators of the passport of the automobile upwards (the quantitative and qualitative criteria are offered) is developed. The obtained ranks of technical indicators allowed to develop practical recommendations for improving the structure of the passport for highways of state and local importance. The developed economic-mathematical model for determining the criterion of performance evaluation (KE), allows you to quantify the effect of improving certification and reducing the financial costs of these works. The economic effect of this model from the implementation of the results of the study is 23.4 thousand UAH for the certification of 1 km of state roads and 33.5 thousand UAH for the certification of 1 km of local roads. The total effect within the entire road network of Ukraine is UAH 3.5 billion. A five-level qualimetric model has been developed to generalize the evaluation of the efficiency of road certification, taking into account the multiparametric and hierarchical data. Based on the ranked results of the study of technical indicators of the highway passport by the level of their weight, it was established: 58 technical indicators (4.0% of the total) are in the range of 0 - 0.1 (very low level of weight); 17 technical indicators (22.0% of the total) are in the range of 0.1 - 0.25 (low level of weight); 89 technical indicators (47.8% of the total) are in the range of 0.25 - 0.5 (average weight level); 342 technical indicators (23.8% of the total) are in the range of 0.5 - 0.75 (high level of weight) and 34 technical indicators (2.4% of the total) are in the range of 0.75 - 1 high level of weight). The most effective are the use of remote sensing methods (efficiency of the method Epak = 0.80), unmanned aerial vehicles (efficiency of the method E_PAK = 0.60) and instrumental surveys using laser scanning (efficiency of the method Epak= 0.58) to collect data at road certification. Practical recommendations for improving the structure of the passport for highways of state and local importance have been developed. According to the results of the study, the number of objects in the highway passport was reduced from 85 to 45, or 47%.
