Traffic Engineering

Class code: 003685
Bargaining unit(s): 202
Classification title: Transportation Generalist
Function: Traffic Engineering (with CADD)
Kind of work: Basic level technical and/or skilled maintenance work

Nature & purpose

Under general supervision an employee in this class assists in performing basic and/or skilled construction, operations and maintenance work; assists in the preparation of traffic construction plans; collects data for traffic engineering studies; and performs other traffic engineering activities to ensure requirements of the work unit are met; performs related work as required.

This level is different from the Transportation Associate level in that it requires less direct supervision.  At the Transportation Generalist level, daily work and projects are assigned by the supervisor and/or lead worker. Work/projects are completed with a higher level of discretion than at the lower level.  An employee modifies simple established procedures to improve work processes.

An employee resolves semi-routine yet similar problems using defined approaches learned through work.  An employee at this level is responsible for completing daily work assignments and may identify service needs not currently being met by either taking care of it or bringing it to the attention of the supervisor/lead worker.  Some employees may provide work direction to others as part of a specific assignment.
