SOFTWARE FOR VISUALIZATION OF INFORMATION ON THE STATE OF ROAD NETWORK OBJECTS

Tsesar Alexey Alexandrovich, Ivashchuk Olga Alexandrovna

A brief review of geoinformation systems, the most common in Russia, is made. The possibilities of software for visualizing information about the state of road network objects, created by domestic developers, are described in more detail. The basic principles underlying the development of specialized software for visualizing information about the state of road network objects are given and a brief description of the main subsystems is given. The visualization subsystem and the calculation system are considered in more detail. The joint use of subsystems for storage, information visualization, calculations and output of data on the state of road network objects ensures the implementation of all software functionality. The dependences for calculating the index of the road surface condition on the basis of monitoring data collected by mobile complexes for the multi-criteria assessment of the operational state of the objects of the road network "ADS-MADI" are given. The necessity of taking into account environmental factors, the properties of pavement materials, the quality and timing of repairs, the sufficiency of funding in assessing the index of the condition of the pavement and predicting the residual life of the pavement is substantiated. The results of visualization of the results of monitoring the objects of the street and road network of the city of Moscow in 2019–2020 are presented. in the form of diagrams and on the "heat map". The resulting pavement condition index values can be used by decision makers to assess the condition of the pavement, predict the time required for maintenance and repair activities, and estimate future funding needs.
