INFORMATION TECHNOLOGY OF TRANSPORT INFRASTRUCTURE MONITORING BASED ON REMOTE SENSING DATA

Context. In the light of current road network monitoring practices, this study aims to explore the capability of remote sensing technologies to solve the problems of increasing the objectivity of preliminary evaluations of the condition of the infrastructure as a whole. The object of the study was to process the monitoring of transport infrastructure (TI) to find ways to improve it in the implementation of development projects. 
Objective. The goal of the work is to increase objectivity of decision-making on the evaluation, reconstruction, development of the transport network structure due to the visual presentation and disclosure of open data for monitoring the transport value. 
Method. Existing approaches to TI monitoring and evaluating its condition are analyzed. The identified shortcomings, as well as the development of remote sensing technologies, open up prospects for the use of remote sensing data in the TI monitoring process. A set-theoretic model of the monitoring process information flows is proposed, the consistent refinement of the elements of which made it possible to develop information technology (IT). Formation of a set of input and output parameters of IT, the set of its operations, their representation with IDEFX-models set explains how a set of heterogeneous (graphic, text, digital, cartographic, etc.) data about TI elements coming from different sources are processed and presented to support decision-making on the survey of existing infrastructure and its improvement. The developed IT makes it possible to obtain complex indicators for analyzing the TI of a particular area, to solve the problems of inventorying objects, TI and its elements modeling, taking into account the physical and geographical location, which makes it possible to consider it as an auxiliary tool that complements existing methods of TI monitoring. 
Results. The developed IT was studied in solving the problem of monitoring the TI section of the Kharkiv region using satellite imagery of medium (Sentinel–2) and high (SuperView-1) resolution and the results of laser survey of the road bridge across the river Mzha (as an element of infrastructure). 
Conclusions. The conducted experiments confirmed the operability of the proposed information technology and showed expediency of its practical use in solving the problems of obtaining generalizing characteristics of the infrastructure, inventory of TI objects and their modeling. This opens up opportunities for substantiating project decisions for the reconstruction of the transport network and planning procedures for examining its condition. Prospects for further research may include: creating reference models of TI objects, expanding the table of decryption signs of road transport infrastructure objects, integrating remote data, survey results of TI sections and engineering surveys of objects to obtain evaluations of the condition of TI in general.
