MONTGOMERY COUNTY GOVERNMENT Code No. 4117
ROCKVILLE, MARYLAND Grade 20
TRANSPORTATION SYSTEMS TECHNICIAN LEADER I
DEFINITION OF CLASS:
This is skilled technical and lead level work involving the field and bench assembly, installation, wiring, testing, and routine maintenance and repair of traffic monitoring and traveler information equipment (e.g., traffic control cabinets, signal heads and school flasher assemblies, overhead and underground wiring and communications cable, microwave links, variable message signs, lane control and channelization devices, video cameras, traveler advisory radio system and related equipment). Contacts are primarily with the employees of the crew to which a position of this classification is assigned and employees outside the work unit and others (e.g., police), normally to pass and receive information which facilitates accomplishment of assigned duties and responsibilities. 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 leading and participating in the work of a crew assigned primarily to either traffic signal maintenance or the above-ground installation (overhead construction) of traffic control, monitoring and information dissemination equipment. The work of this class includes routine set-up, maintenance and repair of traffic signal control devices and related ATMS and FiberNet devices (e.g., video cameras, radio transmission equipment, fiber optic cable plant) which can be accomplished in the field or in a shop environment. Work assignments are received from the unit supervisor along with general shop priorities and time requirements identified; the employee must plan and coordinate daily work with crew members and, as required, with other crew leaders. Work is occasionally checked upon completion for compliance with intersection requirements as specified. Guidelines for accomplishing the work are established in the form of unit standard operating procedures, technical manuals, codes and references; from these sources the employee selects how best to accomplish the tasks. The complexity of the work is marked by the employee's application of technical knowledge and skills to a variety of equipment produced by different manufacturers. The purpose of the work is to ensure the safe, efficient installation and maintenance of field equipment supporting the Transportation System Technical Centers capital and operating projects and programs. The work is primarily performed outdoors in the midst of or adjacent to moving traffic, and from considerable heights (bucket truck). Strict observance of safety precautions and procedures is required at such times that the employee is working around high voltage electrical wires. An employee in this class must possess good strength and agility in order to, on an occasional basis, lift objects weighing between 50 and 100 pounds.
