Leveraging Weather Information to Cost Containment, Profitability, and Safe
Operations/Travel This document is used to specify the understanding of
requirements between the Stakeholders and SCSU Research Principal Investigators
for the purpose of implementing a Rural ITS Solution for the Lower Savannah
Region to meet the following objectives: n
Improve transportation safety n
Improve transportation security The document is divided into three parts: n
Project Objects n
General requirements and constraints n
Specific requirements and constraints. The National ITS Architecture was developed for the US
Department of Transportation (USDOT) as the framework for implementing modern
transportation operations systems. The national ITS Architecture provides a common structure
for the design of intelligent transportation systems. It defines the framework around which
different design approaches can be developed, each one specifically tailored to
meet specific regional requirements, while maintaining the benefits of a common
architecture within current (legacy) and planned systems. The National Architecture can provide short-term benefits
by saving time and money in the development of a project from its inception
through its implementation, since it: n
Correlates requirements and problems to services
that must be performed, thus providing trace ability for a project to overall
transportation needs. n
Illustrates efficiencies that can be gained by
eliminating redundant implementations of similar functions. n
Provides a view into the future to identify
services and functionality that may not have been initially considered,
currently needed, or even feasible. This
provides a checklist of future capabilities that could be planned for now in
anticipation of future requirements. n
Provides an extensive list of the transportation
agencies (by matching the functions they perform with the corresponding
subsystem names in the National ITS Architecture) that an agency should
consider talking to during initial planning of an implementation. n
Defines the kind of information one should
consider sharing among these agencies.
The agency can use this information as a checklist in planning the
project and in discussions with other stakeholders to show how they can
participate through sharing of the information. n
The following information was obtained from the South
Carolina Department of Transportation website. n
A fog mitigation system that monitors visibility
conditions is in operation on I-526 near the Cooper River in Charleston. n
Closed circuit television cameras are being
utilized on the Grace Memorial and Pearman bridges in Charleston to detect
roadway traffic incidents. n
The South Carolina Department of Transportation
(SCDOT) is in the process of developing a traffic surveillance system\motorist
information system on Interstates 26 and 1-26 in Columbia, and I-85 in
Spartanburg. n
The SCDOT and various Metropolitan Planning
Organizations (MPO) have implemented a motorist assistance program. This program is being used in many urban
areas within the State. The name of the program is “State Highway Emergency
Patrol” (SHEP). n
An ITS study has been proposed by the Central
Midlands Regional Planning Council of Columbia. n
SCDOT has
made a significant investment in upgrading traffic signal systems throughout
the state. n
South Carolina is a participant with other
Southeastern states in developing a commercial vehicle operations (CVO)
institutional issues study n
A pilot "One Stop Shop" for CVO
permitting has been implemented in Columbia The SCDOT, working with the FHWA Division Office, selected
Lockheed Martin IMS for the private operation and maintenance of a toll system
on the Cross Island Parkway in Hilton Head. The 7.5-mile Cross Island Parkway
has one toll plaza with 14 lanes and two ramps with two lanes apiece. ITS
technologies to be included in the system will consist of, but not be limited
