Various methods of collecting data on passenger traffic, their advantages and disadvantages are considered. It is shown that in order to improve the quality of transport services, it is necessary to regularly collect and refine data on passenger traffic. The goals and methods of obtaining information about passenger traffic in the system of municipal passenger transport are indicated. All currently existing methods are divided into three categories: data collection using technical means, data collection with the help of censors and volunteers, and interpretation of fare payments. All the methods presented in the article were compared in terms of labor intensity, costs and accuracy of the results obtained. The advantages and disadvantages of each method are considered. The general structure of an automated system for collecting data on passenger traffic is presented. The necessity of creating a centralized system for collecting and processing data associated with all passenger transport control systems has been substantiated. The tasks solved by this system at all levels of transport services for passengers are shown. Each of the tasks is assigned to one of three service levels: pre-transport, transport and post-transport. It is shown that only solving problems at all levels can ensure high-quality operation of the municipal passenger transport system.

This article focuses on the launch of Sputnik that transfixed the world by Carpenter Technology Corp. By incorporating advanced processing equipment, including a rolling mill, shape controller, annealing furnaces, wet grinders, and leveler with state-of-the-art automated control systems, Carpenter has improved the productivity and quality of its high value strip at a time when Space Shuttle launchings are taken in stride. The Carpenter specialty strip facility installed a cold rolling mill designed by Joseph Frohling GmbH of Olpe, Germany, in November last year, to increase rolling capacity and guarantee that the steel strip it produces meets the desired shape and thickness. In the Frohling mill, strip passes between two working rolls that reduce its thickness to sizes between 0.150 and 0.008 inch, at speeds up to 1500 feet per minute. Carpenter also installed three Ebner vertical annealing furnaces. Coiled strip on mandrels is unwound through each furnace, annealed, then rewound continuously to promote productivity.

In Ukraine, the condition of surface water near industrial enterprises is extremely critical. The operation of enterprises leads to intensive water pollution with industrial and domestic wastewater. Therefore, improving the quality of treatment facilities through the introduction of automated control systems is an urgent problem. For the operation of automated control systems for typical cleaning processes, a software package is required, which is developed on the basis of appropriate algorithmic software and mathematical models of processes. To obtain them, methods of mathematical and simulation modeling and block diagram method of algorithmization were used. In order to assess the quality of the developed algorithm for controlling the process of buffer wastewater neutralization during operation, a comparison of control system operation based on this algorithm with the most successful foreign variants of neutralization control systems was made. Simulation for the average values of operating parameters Q = 75 m3 / h, CP = 75 g / l, and Ck = 2 g / l at minimum b = 0.02 g / l pH and maximum buffer value b = 0.47 g / l pH, and also with  unidirectional extreme combination of parameters Q = 50 m3 / h, CP = 100 g / l, b = 0,02 g / l pH and Q = 100 m3 / h, CP= 50 g / l, for minimum b = 0.02 g / l pH and maximum buffering value  b = 0.47 g / l pH shows that the best quality of transient processes is for the control system operating on the basis of the developed algorithm. For any combination of parameters, the transients for this control system provide better quality transients. Studies have shown that the control system based on the developed algorithm in comparison with the previously proposed systems provides better process control by reducing the time of transients and reducing the dynamic deviation of the output parameters, which improves the quality of wastewater treatment. Given the non-stationary process and high requirements for the cleaning parameters, manual control of this process is beyond the power of even an experienced operator. The developed mathematical model describing the dynamics of the wastewater neutralization reactor with buffer properties and the process control algorithm made it possible to proceed to the development of the control system software, which is necessary for the automated control of this process.

One of the requirements of our time is a high-quality public transport service for passengers. Reliability and regularity of traffic, duration and comfort of the trip, traffic safety, availability of equipped and convenient stops - all this and many other factors affect the quality of passenger service. The peculiarities of the organization of passenger transportation, as well as the performance of city routes, affect the psychophysiological state of a person and, as a result, the functional state and the degree of passenger fatigue, which leads to a decrease in his income. The study identified and analyzed the performance indicators of competing routes, which duplicate each other: bus route №276e and trolleybus route № 46. Based on the analysis of studies in the field of the quality of the provision of services by passenger transport, a survey form was formed on the quality of transportation on the routes of urban passenger transport. The assessment of the degree of consistency of experts' opinions using the Kendall coefficient of concordance indicates the consistency of expert opinions. Most of the criteria that were determined by passengers (interval of movement, the degree of filling and the service life of the vehicles) are indicators of the operation of the route, affect the passenger's transport fatigue and a decrease in the passenger's income. The change in the level of transport fatigue of the passenger during the waiting periods and at the end of the route trip in general along the directions of movement and on the individual hauls of the routs are determined. When assessing the quality of transport service on routes, the obtained values of transport fatigue indicate that when using routes, the condition of passengers is assessed as "good". But, if we consider the state of the passenger while using the individual hauls of the routes, his transport fatigue changes significantly and is assessed as "satisfactory". The value of a decrease in passenger income on routes increases throughout the trip, due to the dense filling of the vehicle interior, which negatively affects the functional state of the passenger. Under the existing conditions of passenger transportation on routes, the value of passenger fatigue and the value of passenger income reduction on bus route No. 276e exceeds the value of this indicator on the trolleybus route. To improve the organization of the bus route No. 276е, it is proposed to update vehicles and use buses with a larger passenger capacity (III class instead of I and II, which are used on the bus route now). After the implemented proposed measures for the busiest direction: the occupancy rate of the bus cabin decreased from 1,05 to 0,36, transport fatigue decreased from 5,5 points to 3,03 points, respectively, the value of the decrease in income from 60,55 UAH to 51,53 UAH. Updating vehicles on the Kharkiv bus routes are an urgent problem that requires an immediate solution to improve the quality of passenger transportation. The use of obsolete vehicles on city bus routes affects not only the passenger's fatigue, but also the drivers and, as a result, the likelihood of an road traffic accident. A significant adverse factor affecting the driver is the air pollution of the vehicle interior with harmful compounds, especially carbon monoxide.

Passenger transport of the country has a significant impact on the level of its economic development, providing the connection of the population with objects of industrial, social, cultural and household purposes.In Russia, intercity passenger transportation by public transport is mainly represented by bus, rail, aviation (aircraft) and water (domestic). The article analyzes the dynamics of passenger transportation and passenger turnover of public transport for the period from 2015 to 2020, presents a calculation of the number of flights performed by bus, rail, air (aircraft) and water (domestic) transport, identifies the reasons for the lack of development of passenger transportation and suggests solutions.It is established that inland water transport is currently undergoing decline and state intervention is necessary for their development. Also, during the period under review, there is a decrease in the popularity of buses and a preference for private transport to public, it is necessary to improve the quality of transportation. The indicators of air and rail transport have positive dynamics, but they also require growth. The development of air transport in Russia can be carried out by the introduction of new services, for example, air taxi, rail-transport in the field of urban and suburban communications, the construction of new high - speed highways. In 2020, due to the announcement of restrictions on movement and quarantine measures, there is a sharp decline in indicators for all types of transport.The materials can be used to analyze and improve the work of the country's passenger complex.
