CLASS SPECIFICATION
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.
