Summary Information

The Transportation Management Center Staffing and Scheduling for Day-to-Day Operations technical document provides guidance, useful strategies, suggested approaches and techniques, and recommended practices to assure transportation management centers (TMCs) are adequately staffed to meet service demands.

The study indicated that personnel payroll costs are most often the predominant cost factor in O&M budgets for service operations. To be cost-effective, TMCs must generate efficient schedules and optimize staffing levels.
