TRB’s Transit Cooperative Research Program (TCRP) Report 184: Maintenance Technician Staffing Levels for Modern Public Transit Fleets identifies existing tools and practices used to determine optimum maintenance technician staffing levels. The report also provides an analysis of variables that influence maintenance technician staffing needs.

In addition, the report documents an MS Excel-based Maintenance Staffing Calculator produced along with the report. The tool is designed to help managers of transit agencies of any size to:
(1) break down staff by location or sub-fleet;
(2) adjust raw employee numbers to full-time equivalents and available productive hours using information on current technician staffing, other employees contributing to maintenance, breaks, vacations, and shift information;
(3) calculate preventive maintenance, core maintenance, and unscheduled maintenance task hours required by sub-fleet;
(4) calculate heavy maintenance and repair hours required;
(5) model effects on staffing of changes to fleet composition or usage;
(6) model effects on staffing of changes to maintenance times or intervals, accounting for overtime required; and
(7) compare results to a group of peer agencies.
