The cost of O&M at the Arizona TMC was estimated at $2 million per year.
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. The data below extracted from Figure A.2 (2005) of the source report identifies O&M cost items in the Arizona TMC budget.
|Equipment and Supplies|
The Arizona TMC operates 24/7 and performs three primary functions: Incident Management, Traffic Management, and Traveler Information. The TMC includes an administrative unit, a project development unit, and a unit that maintains day-to-day operations at the TMC. Each day includes three shifts: morning (6:00 AM to 2:00 PM), evening (2:00 PM to 10:00 PM) and night (10:00 PM to 6:00 AM).
Staffing levels for day-to-day operations were reported as follows:
- Full-time state employees (1 Operations supervisor; 3 Operations shift supervisors; 9 Operators)
- Part-time students and interns (3 Operators per shift)
