VEHICLE MAINTENANCE: COST RELATIONSHIP AND ESTIMATING METHODOLOGY

Abstract

An investigation into maintenance costs and programs at transit properties throughout California is summarized. The objectives of the research were to study and report on maintenance cost information, and on the need for maintenance management support. The materials presented in this paper are intended to aid maintenance managers in planning, managing, and controlling maintenance costs and effectiveness. Cost relationships are presented for the estimation of maintenance costs by element and maintenance function area. Graphs are presented for estimating total maintenance cost dependent on fleet size and annual vehicle miles. Cost element contributions to total maintenance cost are identified for repair, inspection and servicing labor, fringe benefits, and overhead; maintenance administration, material, and supply cost rates are also provided.
