Traffic Engineering

Class code: 003676
Bargaining unit(s): 207
Classification title: Transportation Generalist Senior
Function: Traffic Engineering without CADD
Kind of work: Intermediate level technical, skilled work and/or lead worker

Nature & purpose

Under general supervision an employee in this class performs moderately difficult construction, operations and maintenance traffic engineering work: prepares traffic control, signing, pavement marking, signal, lighting plan sets; gathers data and prepares special studies; performs operation and maintenance checks for traffic signals, lighting and Intelligent Transportation Systems; and performs related work as required.

This level is different from the Transportation Generalist in that at the Transportation Generalist Senior level, an employee initiates and/or prioritizes work activities, completes a variety of work assignments, and chooses the methods in which to complete work using acquired knowledge of the function. 

An employee resolves semi-routine yet uncommon problems by searching for solutions learned from experience.  An employee is responsible for completing multiple projects and/or work activities with competing deadlines and may set some priorities in the completion of work.  Some employees at this level may perform as lead worker having considerable freedom to organize human, equipment, material and other resources as well as prioritize, schedule, assign, direct, guide and report on the work activities of other state employees.

Examples of work

A position may not include all the work examples given, nor does the list include all that may be assigned.

  • Reviews the work of contractors to verify construction conforms to MnDOT traffic specifications/plans and keeps engineer informed as necessary.
  • Creates, updates, and archives as-built plans.
  • Develops and implements basic traffic signal timing parameters in accordance to with MnDOT standards.
  • Performs operational and maintenance checks to ensure the signal functions correctly.
  • Reviews construction plans for accuracy and provides comments to other functional areas.
  • Gathers data such as sight distance, safety, no passing, infrastructure inventory, Before/After, crash, etc. to complete special studies.
  • Analyzes the traffic data for reporting, planning, and study purposes.
  • Updates and maintains crash information/databases and creates detailed crash studies using Transportation Information System (TIS) and Geographic Information Systems (GIS) software.
  • Responds, orally or in writing, to customer inquiries/request by translating technical information into responses easily understood by the general public.
  • Completes basic plat/permit reviews and assists in the completion of more complex plat/permit reviews.
  • Provides technical assistance to construction inspectors and contractors in the field, as needed.
  • Prepares signal, signing and pavement marking work orders for traffic modifications performed by maintenance within set deadlines.
  • Assists with implementing traffic control plans in the field.
  • Perform field review of operational conditions of the electrical systems to assure that optimal system performance is occurring and that all new and existing maintenance and repair needs are noted and documented in the AFMS database.
  • Conduct field reviews to assure lighting, signing and striping (permanent and temporary) are implemented according to work orders, project objectives and/or MnDOT specifications.
  • Operate and maintain all vehicles, tools, equipment and communications devices so that optimal performance and condition of those assets is assured, that all record logs are maintained and monitored, and all repairs are promptly requested and scheduled.
