The Life Cycle Cost for the definition of the correct use of the drive system chosen by the local public transport operators

Introducing lots of buses into the operator's fleet TPL is linked to many variables such as eligibility, environmental sustainability, infrastructure, the characteristics of the line to maintain, etc ... The analysis of the maintenance data and Life Cycle cost of buses with different diesel traction systems, CNG, Hybrids, battery electric, ecc.. who currently dominate the TPL scene allows to verify the temporal evolution of the costs. There LCC methodology is the only one that allows you to keep tabs on maintenance costs and to improve the product through the bus manufacturer's involvement in the operation phase. Through the experimental validation of corporate data of technologically more mature traction systems, it has highlighted the need for the operator to TPL which must introduce more sustainable transportation systems, to characterize them on the basis of LCC methodology. In this article of research we’ll try to demonstrate how the LCC method allows to point out the defects of the bus components and optimize using the bus on lines with particular morphological characteristics and commercial speed.
