SUPERVISOR, TRANSPORTATION SYSTEMS TECHNICAL CENTER
DEFINITION OF CLASS:
This is skilled technical and first level supervisory work involving the County wide construction, modification, installation, testing, maintenance and repair of traffic control, traffic monitoring and traveler information equipment, devices, and sub-systems supporting the County's Advanced Transportation Management System (ATMS). Contacts include unit employees to assign and evaluate work; parallel units and employees from other government agencies to plan and coordinate the work of the unit; and private contractors and equipment vendors to coordinate purchase, installation and use of equipment. This class of work may entail some public service/assistance, but it is incidental to the primary focus of the work performed.
An employee in this class is responsible for planning, coordinating and scheduling the safe installation, repair and maintenance of the equipment, devices and subsystems of the Montgomery County transportation management system, including traffic signal devices, fiber optic cable plant and related components including base and broad band video equipment, video traffic surveillance cameras, traveler advisory radio system, variable message signs, lane control and channelization devices, and related telephone and data communication equipment. Work is performed under general supervision of a traffic engineer who provides the employee with a schedule of projects and completion dates and general assignments for nonroutine work; the employee is expected to plan and coordinate the work of unit subordinates in such a manner as to meet the prescribed work objectives within established schedules. While the work of the unit is reviewed and evaluated for compliance with instructions and schedules, normally the means by which the work is accomplished are not reviewed in detail. Guidelines are available in the form of engineering plans, manufacturers' technical manuals, national and state codes and other references to which the employee refers for technical assistance. The employee exercises independent judgment and ingenuity, under the general guidance of the engineering staff; to modify and adapt standard technical procedures and practices related to equipment use and installation in order to accomplish the unique requirements of the County's transportation management system. The complexity of the work is marked by the technical knowledge required of the employee to be proficient in the field of electronics, the sophistication of the traffic control and monitoring equipment and devices implemented in the County's ATMS system, the potential for increased technological development and expanded communication capabilities, and the challenge of managing a unit consisting of a diverse staff of construction and technical employees. Impact of the work is significant in that the employee is responsible for overseeing the work activities of the unit in planning, coordinating and scheduling the systems supporting the ATMS. Supervision of installation, maintenance and repair of traffic control, monitoring and other communication equipment occurs primarily in a clean shop environment with occasional field trips to projects at outdoor locations. Strict observance of safety precautions and procedures is required at such times that the employee is working around electrical voltage, high powered equipment and fiber optic materials and equipment. An employee in this class must possess good strength and agility in order to occasionally lift objects weighing 20 to 50 pounds.
