A Quick Response Light Rail Transit Operation & Maintenance Cost Utility Tool to Perform Sensitivity Analysis

Determination of the unit cost of supply variables is challenging. At present, to develop unit cost, the expenses assigned to each supply variable are summed and divided by the annual quantity supplied. Such an approach tends to overestimate, because there is no reasonable or analytical way of determining the expense allocated to each supply variable.There is a need to develop a total operation and maintenance (O & M) cost model and other types of models that only consider some supply variables and not the unit costs. The objective of this study was to develop a standard O & M model by analyzing the system data of 12 peer light rail transit (LRT) facilities. Attempts were made to derive relationships among cost components and various system variables. In this effort, a utility tool was developed that includes a set of nomographs and a cost calculator to be used to estimate the total O & M cost and its components. The main focus of this work was to develop a tool that can quickly produce a firsthand estimate of LRT total yearly O & M cost based on the input values of system attributes.
