Example OrganizationDOT District EngineerDOT District <strong>Operations</strong> Mgr.TMC Manager<strong>Operations</strong> SupervisorLead OperatorSenior OperatorOperatorTraineeAccessibilityIn any situation where supervisory intervention is required, easy access to thedecision maker is essential. Most TMCs place the shift supervisor’s <strong>of</strong>fice in oradjacent to the control room, but typically in a separate <strong>of</strong>fice (providing soundisolation and privacy for handling personnel issues). Supervisors in essentially allTMCs surveyed carried pagers and/or cellular telephones whenever <strong>of</strong>fsite orelsewhere in the building complex.Some systems rely on a lead, experienced operator outside <strong>of</strong> prime shifts, withsupervisory access from home. In these cases, <strong>of</strong>ten the supervisor has thecapability to dial into the computer system (normally without video access dueto communication bandwidth requirements) so that he/she can view thesituation comprehensively before providing direction.Other supervisory <strong>of</strong>ficials, such as the maintenance supervisor, may be similarlyaccessible. This is particularly important in work situations where requiredservices are performed by personnel working under a collective bargainingagreement, whose efforts must be initiated by a member <strong>of</strong> TMC management.4-32Inquiries or Interest from AboveParticularly in difficult situations, the TMC is likely to receive inquiries fromhigher levels <strong>of</strong> agency management, or from other governmental <strong>of</strong>ficials. Theconcept <strong>of</strong> operations should provide direction as to how these inquiries are tobe handled, as the impressions made upon such senior decision-makers canhave a major impact upon their impressions <strong>of</strong> the effectiveness and importance<strong>of</strong> the TMC. In such situations, the balance between responsiveness andauthority is delicate, as is the perspective from which the information ispresented (details critical to the operator may be <strong>of</strong> little interest to seniormanagement).
In situations where inquiries are received from outside <strong>of</strong> the agency, it may beappropriate (or agency policy) to involve or work through the agency’s publicaffairs <strong>of</strong>fice.For TMCs such as Georgia NaviGAtor, Houston TranStar, and San AntonioTransGuide which have dedicated public affairs staff onsite, this process issimplified, although the public affairs staff must be informed about anyemerging situation before taking action.StaffingNumber <strong>of</strong> StaffThe number <strong>of</strong> staff required is one <strong>of</strong> the most important elements <strong>of</strong> theconcept <strong>of</strong> operations. This calculation must reflect all elements <strong>of</strong> theworkload, including how the team is organized and deployed. There are noabsolutes regarding the number <strong>of</strong> personnel per number <strong>of</strong> signalizedintersections, number <strong>of</strong> transit vehicles dispatched, or centerline miles <strong>of</strong>freeway under incident management.The primary determining factor is the set <strong>of</strong> functions which the staff areemployed to deliver. In freeway management, for example, the responsibilitiesmay include only incident management (detection, verification, action,monitoring, closure), or may also include various traveler information functions,interaction with a motorist assistance patrol, control <strong>of</strong> ramp meters, control <strong>of</strong>planned lane closures, and other functions (such as some forms <strong>of</strong> enforcement)which are not directly related to freeway management.TMC StaffingBoston Toronto Long Island Detroit Milwaukee Atlanta Phoenix Houston<strong>Center</strong>line Miles 7.5 60 165 180 63 220 254 122Number <strong>of</strong> OperatorPositionsNumber <strong>of</strong> PrimeShift OperatorsTotal <strong>Operations</strong>StaffNumber <strong>of</strong> OperationStaff Levels<strong>Operations</strong> StaffSource10 9 5 6 3 12 6 183+ 3+ 5 4 2+ 5 2 1210 12 12 9 5 18 8 193 3 2 2 1 1 2 1MassPike asContractorAgency Staff(FT and PT)ContractorPersonnelTemporaryPart-timeStaff,StudentsStaff,StudentsAgency StaffAgency StaffNumber <strong>of</strong> Shifts 3 3 3 2 2 3 3 3Backup <strong>Operations</strong>Staff ResourcesSupervision,Off-shift,OvertimeSupervision,Off-shiftContractorResponsibilitySupervision,Off-shiftSupervision,Pr<strong>of</strong>essionalStaff, Offshift,StudentsSupervision,Pr<strong>of</strong>essionalStaff, Offshift,StudentsSupervision,Off-shiftVaries byAgencySource: Metropolitan <strong>Transportation</strong> <strong>Center</strong> <strong>Concepts</strong> <strong>of</strong> <strong>Operations</strong> Cross-Cutting Study, FHWA (9/99)4-33
