RATIONAL AREAS OF USING BUSES OF DIFFERENT CLASSES OF PASSENGER CAPACITY
Journal Title: Автомобильный транспорт - Year 2018, Vol 43, Issue
Abstract
Problem. One of the key issues of the public transit operating is the choice of vehicles passenger capac-ity. This parameter has a wide range of variation and the basis arises for the segregation of buses into classes. The use of buses of a certain class of pas-senger capacity has rational areas, due to a quanti-ty of parameters characterizing the process of de-mand formation in transit services (passenger flow volume, its spatial and temporal dynamics, etc.). An analysis of existing research of vehicles capacity choice for route operating has shown that they are not well-coordinated and require further research. Goal. The purpose of the article is to determine the rational areas of using the buses of different classes of passenger capacity. Methodology. Mathematical formulations of the problem have been concerned with minimizing of overall costs, that measure as a combination of user and operator costs. As operated variables, the passenger flow and the load factor on the maximum load section of the route were used. Results. As a result, recommendations for using dif-ferent bus classes of capacity were proposed. For the applied input data, rational areas of using buses of different classes of passenger capacity have the following ranges of passenger flow on the maximum load section of the route: from 50 to 280 pass./hour – small capacity buses; from 280 to 1100 pass./hour – medium capacity buses; from 1100 to 2450 pass./hour – large capacity buses; from 2450 to 5400 pass./hour - especially large capacity buses. Originality. In contrast to the existing, the proposed approach allows two-factor optimization by passen-ger capacity and passenger density parameters and takes into account various route parameters, in par-ticular, the characteristics of passenger spatial flow dynamics. Practical value. The obtained results can be used for public transit planning and operation tasks solving, in particular, of vehicles capacity choice on the bus routes. The vehicle capacity de-fined other parameters of transportation such as headway, service frequency, etc.
