Traffic Engineering

Class code: 003677
Bargaining unit(s): 207
Classification title: Transportation Specialist
Function: Traffic Engineering (with CADD)
Kind of work: Senior level technical and/or specialized work

Nature & purpose

Under limited supervision an employee in this class performs difficult technical work preparing and inspecting traffic signing, striping, temporary traffic control, signal, lighting and Intelligent Traffic Systems plans; serves as the technical expert on traffic operations, studies and/or plans; provides expert technical assistance during the construction of traffic systems; assists in the training of staff members; and performs related work as required.

This position is different from the Transportation Generalist Senior in that at the Transportation Specialist level, employees plan and organize work based on deadlines, procedures and standards.  An employee determines what shall be done and how it will be done and continually improves work processes.  At this level, an employee provides technical expertise and information, in a specialized field, to others.

An employee resolves most problems using theoretical principles and concepts of a specialized field as well as knowledge of and impact on the department’s programs.  The employee is considered the technical expert in a specialized area and provides technical support and expertise to others.  A Transportation Specialist is responsible for completing or leading multiple complex projects and/or work activities and has a substantial degree of authority in planning, organizing and completing 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.

  • Investigates traffic control device complaints by identifying problems, making recommendations, and corrections on need and placement of traffic control devices. 
  • Conducts field reviews to assure lighting, signing, or striping (permanent and temporary) are implemented to conform to work orders, project objectives and/or MnDOT specifications. 
  • Perform field review of operational conditions of the electrical systems to assure that optimal system performance is occurring and all new and existing maintenance and repair needs are noted and documented in the TAMS database.
  • Monitors Gopher State One Call on-line for locate requests, locates utilities, or assigns request to others, and documents completed work to ensure reimbursement; upon completion, collaborates with Electrical Services Section to ensure proper utilities documentation.
  • Completes plat/permit reviews Independently. 
  • Coordinates the implementation of traffic plans in the field by acting as liaison between contractors, construction and traffic personnel and inspecting contractor’s work involving construction projects; keeps supervisor informed, as necessary.
  • Gathers data, performs field work, and prepares various study reports independently.
  • Updates and maintains the Linear Referencing System (LRS) crash database so crash reports are correct and complete and independently runs complex reports.
  • Obtains crash information and creates detailed crash studies using CADD, Linear Referencing System (LRS) and Geographic Information Systems (GIS) software so that collision diagrams, concept drawings and maps may be prepared to provide safety information for the project development process.
  • Operates and maintains all vehicles, tools, equipment, and communications devices so 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.
