Draft Report

Procuring, Managing, and Evaluating the Performance of Contracted TMC Services

transportation/traffic engineering departments; organizational models can vary in effectiveness from one region to another.


Public agency staffed and operated, requires operating agency to have skills inhouse as well as budget and training to support these specialized skills; does provide uniform staffing system and maximizes fulfillment of transportation objectives; however, recruitment and retention of staff can be difficult. For the best chance of success, TMC positions need to be created as new positions rather than being carved from existing personnel and operating budget allotments and thereby being forced to compete with existing operations needs.


Private sector staffed and operated, either entirely or in part with public agency supervision.  Allows specification of staff qualifications and places hiring/training burden on the private contractor; monies for contracted staff may be more easily found than monies for operations activities.  There are, however, contractual issues to be dealt with as well as administrative oversight and contractor performance measurement.


Operating versus capital dollar availability for decisions on contracted services must be made when comparing contracted with in-house TMC services.  Operating and capital funds come from different sources within agencies and therefore have implications on staff availability and development.  These are different sources of funds that can be used to pay for TMC services that may be influenced by a state’s financial position.

Table 3 presents examples of organization models commonly found around the country.
