FOREWORD
This report documents
a top-down system analysis conducted during the course of an investigation
of human factors issues critical to the design of an advanced traffic
management system (ATMS). Methodologies employed in conducting this
analysis, procedures for implementing such methodologies, and analysis
results are presented. System objectives and performance requirements
for an ideal ATMS, as well as the functionality for such a system, are
defined. (The ideal system represents a hypothetical ATMS, one that
is unconstrained by real-world events, existing practices in traffic
engineering, or current technologies.) Ultimately, real-world elements
were considered, where idealized objectives, performance requirements,
and functional definition were revised. These revisions are documented
here.
Issues associated
with the human operator (assignment of operator roles to each ATMS function,
specification of operator performance requirements, and identification
of operator tasks) are also addressed. Results of the ATMS function
allocation process are presented. Included in this presentation is an
introduction to the theoretical framework guiding ATMS function allocation:
operator role theory, In this report, assessment of the human operator
begins at a global level and progresses through increasingly detailed
levels. This assessment terminates with the results of a detailed task
analysis. Task analysis results supported the preparation of a human
factors specification for traffic management center (TMC) configuration
items.

16. Abstract
This report documents
an approach for designing an Advanced Traffic Management System (ATMS)
from a human factors perspective. In designing the ATMS from a human
factors perspective, a user-centered top-down system analysis was conducted.
Methodologies employed in conducting this analysis, procedures for implementing
such methodologies, and analysis results are reported. System objectives
and performance requirements for the AIMS, as well as ATMS functionality,
are derived. Human operator issues (assignment of operator roles to
ATMS functions, specification of operator performance requirements,
and identification of operator tasks) are also addressed. Results of
the operator task analysis supported the preparation of a human factors
specification for the ATMS.
