A comprehensive automated system for monitoring the formation, transportation, processing and disposal of liquid production and consumption waste in the region is proposed. The system developed by the authors allows, on a unified information basis, to unite carriers of liquid waste, places of their generation, reception and disposal. The article discusses in detail the software for an automated station for receiving and neutralizing liquid waste, as well as a web-shell that allows digitalizing objects of communal infrastructure, on the territory of which activities for processing, neutralizing, and disposing of liquid waste are carried out. The tools and technologies used in the development of the automated system are indicated. In the final part of the work, the software for routing the transportation of liquid waste is presented and the mobile applications of carriers and waste generators for interaction between the system and its client applications are described.

In this paper, the authors present a method for estimating the longitudinal adhesion coefficient of motor vehicles with road covering on approaches to level crossings. A feature of the technique is the possibility of using as input data in assessing the coupling qualities of road pavements, a large number of variables characterizing both moving vehicles and road paving combined with weather and climate factors. A multi-factor assessment of the adhesion coefficient at approaches to level crossings contributes to the improvement of traffic safety at railroad crossings as part of the development of a road maintenance management system
