This is professional engineering work in the planning, design, installation and improvement of traffic and transportation highway systems and control devices.

Employees in this class participate in and implement transportation planning studies, produce geometric traffic engineering designs of roadways and develop comprehensive traffic signal control systems for the metropolitan area. Work involves the application of professional traffic engineering principles to varied projects related to the safe, convenient and economical transportation of persons and goods over the roadway network of the local area. Duties require the application of basic engineering sciences and transportation theory to expedite the movement of vehicular traffic and to overcome deficiencies in the existing transportation complex. Supervision may be exercised over drafting and data collecting subordinates through assignment and review of work in process and upon completion for accuracy and engineering sufficiency. A professional engineering superior assigns projects and advises on unusual or difficult problems, with completed work checked for conformity with departmental policy and governmental regulatory provisions.
