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.
