TRANSPORTATION DATA COLLECTOR II
Work in this class involves monitoring, recording and managing traffic data over an assigned
geographical area. Within this region, positions have responsibility for monitoring traffic volumes,
vehicle classification, speeds, truck weights and roadway inventories in accordance with statistical valid
sampling programs established in compliance with state and federal guidelines. Work is performed
under the general supervision of a Transportation Data Collector Supervisor and is reviewed through
written reports and occasional on-site observation. Employees may perform other duties and
responsibilities as required.
I. DIFFICULTY OF WORK:
Variety and Scope - Positions in this class perform all of the duties associated with the Transportation
Data Collector I classification, but are distinguished by their primary responsibility for conducting
Highway Performance Management System (HPMS) Traffic Volume Sample and Special Needs
Volume Sample for their assigned area in accordance with the unit's sampling plan and Federal
Highway Administration's "Traffic Monitoring Guide". Positions are responsible for maintaining HPMS
Field-Data Records for all HPMS roadway segments located within their assigned area.
Complexity of Work - Complexity for positions in this class was measured in the programming of
equipment; installation, calibration and operation of various electronical/mechanical data collection
devices; monitoring sample sites to ensure proper equipment operation; performing algebraic
computations while collecting field data for curves and slopes; and analyzing raw data to ensure
completeness and accuracy.
Judgmental Demands - Although standard operating procedures are established, the positions are
responsible for ensuring that field conditions meet the criteria set by the sampling program and
determining if equipment is operating properly. If data does not fall within the expected range,
judgement is required to determine if the study sample should be recollected at the same site, obtain
approval to move the site or research and justify a change in the expected range of data values.
Controls Over Work - Instructions are received in the form of project schedules, verbal directions, maps
and guidance set forth in the Traffic Monitoring Manual. Positions are responsible for a large
geographical region comprised of approximately 10 counties.
II. RESPONSIBILITY:
Potential for Loss - Work could result in improper data to be buried thus affecting study results and
decisions made by other, such as technicians and engineers which use the data to forecast trends and
future growth for projects including traffic control, intersection design and capacity design.
Safety of Others - Work has potential for causing accidents and injuries to the traveling public if
improper traffic control measures are not maintained.
III. MENTAL AND VISUAL DEMANDS:
Visual Attention - Employees must continuously exercise visual attention in all phases of work,
including reading equipment instruments.
Mental Concentration - Work requires substantial mental concentration in order to continuously observe
traffic patterns to carry out assignments.

IV. PHYSICAL EFFORT:
Intensity of Effort - Work performed is characterized by standing, walking, bending and stooping.
Frequency and Duration - Although a considerable amount of time is spent on routine efforts such as
walking, climbing and standing, these involve limited stress and strain.
V. WORK SURROUNDINGS AND HAZARDS:
Worker Surroundings - Work is performed in office and field conditions.
-Employees frequently work next to intersections and roadways with high noise levels.
Hazardous Conditions - Employees are frequently exposed to hazardous conditions relative to working
next to high traffic volumes.
VI. CONTACTS AND COMMUNICATIONS:
Purpose of Contacts - Contacts normally involve the exchange of information but at times include
explanation such as the purpose for conducting origin and destination studies, coordination work.
Scope of Contacts - Contacts are primarily with personnel within the agency; however, limited general
public contact is also required.
VII. RECRUITMENT STANDARDS:
Knowledges, Skills and Abilities - Office/computational work requires a general knowledge of
mathematical functions. Skill in the use and maintenance of office equipment such as calculators and
computer terminals, and electronic data collection devices. Ability to read and interpret information from
sources such as plans, sketches, maps and other field data. Ability to follow verbal and written
instructions. Ability to train others relative to proper installation, maintenance and operation of
electronic/mechanical data collection devices.
Minimum Training and Experience Requirements - Graduation from high school and two years of
experience in the installation, maintenance and operation of transportation data collection devices; or
an equivalent combination of training and experience.
Necessary Special Qualifications - Possession of a valid North Carolina driver's license.
Special Note - This is a generalized representation of positions in this class and is not intended to
identify essential functions per ADA. Examples of work are primarily essential functions of the majority
of positions in this class, but may not be applicable to all positions.
