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.
Document Overview
This document is organized in the following manner:
Section 1 describes the document purpose and scope
Section 2 describes any referenced documents
Section 3 describes the test environment
Section 4 describes test baseline management
Section 5 describes the general test provisions
Section 6 describes data recording, reduction and analysis
Section 7 describes the System Acceptance Test Procedure document.
