The article deals with the problem of improving the traffic management system. In the AnyLogic environment, the workload of a traffic flow is simulated with the calculation of the throughput efficiency. By varying the parameters of the agent-car and the traffic light control system, the optimal values for the duration of the signals are revealed and the shortest time for crossing the intersection is achieved.To analyze the workload of the selected section of the city of Volgograd, a cartographic service was used. An experiment was conducted on a quantitative model, in the form of measuring the parameters of a car stream at different times of the day. The search for the optimal solution to the traffic control problem on a specific section of the road in Volgograd was carried out, for which variable parameters were selected, the objective function was determined in the form of waiting time at the intersection, and the solution of the problem was obtained in the form of traffic light switching times. The advantages of the method include the visibility of the model and ease of use.

The construction industry is considered to be one of the most unsafe industries, and as a result, safety in the construction industry is considered a very important factor. To reduce the number of accidents and monitor workers at a construction site, the article suggests integrating new tracking and communication technologies. The authors analyze the existing similar technological solutions, identify their advantages and disadvantages. A method for organizing monitoring of workers at a construction site using mobile devices is proposed, as well as the architecture of a software and hardware complex. The developed method is a smart system for a mobile device. This solution allows you to monitor the location of workers using a GPS tracker and a built-in accelerometer, and, if necessary, notify them of a possible danger.
