Evaluating Passenger Carrying Capacity of Buses for Urban Public Transportations

Introduction. For urban agglomerations, public transportation is of crucial importance - it provides mobility of population at minimal cost and within minimum urban space, acceptable negative environmental impact being achieved. This paper considers the problem of estimating passenger carrying capacity of vehicles for operation on urban public routes. The solution is based on determining optimal ratio between parameters of efficiency and quality of public transportation.

Materials and Methods. In this article based on empirical data from transport organizations it has been shown that the cost of bus operation is linearly dependant on its capacity. On the other hand, the costs per passenger-seat are of non-linear character. With the same tariffs to ensure profitable transportation buses of smaller capacity should be operated with a higher degree of passenger compartment occupancy, as a result the quality of transportation suffers. Recommendations on selecting vehicle passenger carrying capacity for operation on urban regular routes taking into account the unevenness of passenger flows, as well as the influence of the used class of rolling stock on the efficiency (economic parameters) of the transportation process have been given.

Discussion and conclusion. The effectiveness of the developed methodology for determining the passenger carrying capacity of rolling stock to operate on regular urban routes is shown based on test calculations for a real route of Krasnoyarsk city.
