CLASS SPECIFICATION
TRAFFIC MANAGEMENT TECHNICIAN II
DEFINITION OF CLASS:
This is traffic engineering and management work of a paraprofessional nature
at the full performance level. Employees in this class have contacts with engineers,
contractors, consultants, utility companies, the general public, and related
County, State, and other public agency personnel to exchange information and
provide advice and/or guidance. Contacts require interpretation of requirements
and discussion of technical problems, and facilitating the provision of a particular
process or service such as traffic management plan implementation, data analysis,
and traffic surveillance. This class of work may entail some public service/assistance,
but it is incidental to the primary focus of the work performed.
Employees in this class work rotating shifts and weekends, and are responsible
for the daily operation of an automated traffic management system including
operating a central traffic signal computer, identifying traffic problems and/or
malfunctions within the system, dispatching the appropriate service technician,
participating in the management of traffic incidents, and conducting traffic
engineering studies and analyses. Employees receive work objectives and deadlines
with assignments and independently plan, coordinate, and perform the work, resolving
most conflicts and referring only unusual or unprecedented situations to the
supervisor for assistance. While positions in this class are non-supervisory,
employees periodically provide training and assistance to Traffic Management
Technicians I. Work is reviewed upon completion to ensure technical soundness
and conformity to standard operating procedures, policies and objectives. Guidelines
include industry standards and State and County codes and regulations that are
not always completely applicable to the work and may require adaptation or modification.
Performance of the work requires specialized technical knowledge of computers
and their application to traffic signals, the impact of traffic signal timings
and phasings upon traffic management, and the design and operation of traffic
signal systems. The complexity of the work of this class is characterized by
assignments that involve a variety of processes and methods, and require consideration
of many factors and an understanding of interrelationships among these factors,
i.e., performance of engineering computations, preparation of recommendations
for alterations in traffic flow, implementation and the assessment of the effectiveness
of traffic management changes during a highway incident. Efforts of these employees
involve treating a variety of traffic management issues, and adapting precedent
or established procedures as necessary to accomplish objectives. Work affects
the overall operation of traffic on County roadways on a daily basis through
the development of refinements in traffic controls and the resolution of traffic
management problems. Employees in this class perform field investigations or
traffic surveillance, which entails working in an environment that involves
moderate discomforts and risks such as exposure to operating equipment at construction
sites, moving traffic on the highway, observation from an aircraft, and driving
in traffic. A reflective vest is worn when working in close proximity to moving
traffic. Employees are required to operate a motor vehicle.
EXAMPLES OF DUTIES:
Operates a computer-controlled traffic signal system making changes and adjustments
independently based on real time conditions on the roadways, and coordinates
the management of traffic during an incident or traffic disruption, i.e. an
accident or road construction activity.
Monitors the operation of the computerized traffic signal system and the formulation
and input of data base information. Calculates signal phasing and timing, and
prepares time-space diagrams.
Conducts comprehensive traffic surveys to collect data to be used in controls;
prepares graphs, tables, maps, and accident reports related to traffic, pedestrian
safety, and highway design.
Develops recommendations and prepares plans for traffic control measures such
as traffic signal timings, traffic system parameters, and changes in geometric
design. Performs related duties as required.
MINIMUM QUALIFICATIONS:
Experience: Thorough (5 years) experience in paraprofessional traffic engineering
with a concentration in traffic signal and/or operations that has required the
application of the principles of traffic engineering and mathematics to the
solution of traffic engineering/management problems involving traffic control,
capacity, vehicular speed, and related matters; including some experience in
traffic signal computer operation.
Education: Completion of high school or High School Certificate of completion
recognized in the State of Maryland.
Equivalency: An equivalent combination of education and experience may
be substituted.
Knowledge, Skills, and Abilities:
Knowledge of the principles and practices of traffic engineering and traffic
management as they concern developing refinements in traffic control systems
and the resolution of traffic management problems.
Knowledge of mathematics, including algebra and geometry, as well as the methods,
equipment, and techniques for planning, designing, estimating costs, and monitoring/inspecting
traffic engineering projects.
Knowledge, or the ability to acquire knowledge of County, State, and Federal
laws, codes, and regulations pertaining to traffic engineering and management.
Knowledge of the methods and procedures of operating a central traffic signal
computer system.
Ability to read and interpret traffic engineering plans and specifications and
to convey their meaning to others.
Ability to work with coworkers, contractors, engineers, and other public agency
and County employees to obtain, clarify, and provide information, discuss and
resolve technical traffic management problems, and to provide advice or guidance.
Ability to independently perform field investigations and surveillance in environments
that present moderate discomforts and risks.
Ability to communicate instructions and decisions over a two-way radio.
Ability to react to situations clearly and completely and make independent judgments
and decisions regarding traffic management and control.
LICENSE: Possession of a valid motor vehicle operator's license.
PROBATIONARY PERIOD:
Individuals appointed or promoted to this class will be required to serve a
probationary period of six (6) months, during which time performance will be
carefully evaluated. Continuation in this class will be contingent upon successful
completion of the probationary period.
MEDICAL PROTOCOL: Core Exam.
Class Established: July, 1990
