System Acceptance Test
Plan
for
CARAT
Scope
Identification
This document is the System Acceptance Test (SAT) Plan
for the Congestion Avoidance and Reduction for
Automobiles and Trucks (CARAT) Traffic Management System
(TMS) of the North Carolina Department of Transportation
(NCDOT).
Purpose
The purpose of this document is to specify the plan for
performing the CARAT System Acceptance Test which will
formally verify the CARAT system.
Scope
This test plan applies to the overall system and relates
to system-level tests to verify compliance with project
functional requirements. The Hardware Compatibility Test
(HCT) is part of the subsystem tests. Some levels of
unit testing, subassembly testing, and subsystem testing
may be completed and documented separately.
This plan provides:
Description of the test environment
Description of text baseline management
Definition of general test requirements
Definition of levels of tests
Definition of test classes
Definition of qualification methods
Sample of items that will be provided in the System
Acceptance Test Procedure document:
Test description
Test definition (procedures)
Requirements verification matrix
NCDOT Relationships to the SAT
NCDOT has the contractual right to observe all aspects of
informal and formal CARAT testing in the ATSC ITS lab,
the ATSC CARAT lab, and the TOC.
NCDOT has the contractual responsibility to be present
during the HCT and SAT in order to officially verify that
the CARAT system meets all requirements.
System Overview
CARAT will provide the infrastructure required to
accomplish not only the CARAT goals but also the NCDOT
long-term goals. This infrastructure will include the
systems and services to support the planning and
execution of the CARAT mission operations in addition to
providing a platform for future expansion and
improvement. To accomplish this goal, the following
requirements must be satisfied:
The design must specify open and expandable modular
architectures and utilize COTS products to the maximum
extent. Standards-based COTS components will reduce the
risk and cost of development and test, and allow the
insertion of new technology for future applications.
A proven operations engineering process must be
established with the participation of the CARAT systems
engineering organization.
