SAN DIEGO, CA and MCLEAN, Va., Sept. 15, 2005 -- Science Applications International Corporation (SAIC) and Meridian Environmental Technology, Inc., have teamed up to create a system that delivers integrated information on road, weather and traffic conditions to maintenance and traffic operations managers.

Developed in response to the growing need for proactive road weather management, the system provides decision support and works to integrate information and workflow across agency boundaries. Professionals from different cities, counties or states can use the system together to create an accurate and seamless picture of road conditions in their area. The technology behind this product is designed to provide users with the integration of data necessary to make decisions on immediate travel problems as well as long-term maintenance management issues.

The joint efforts of both companies have lead to the development of the system. Meridian Environmental Technology has brought its expertise in the management and integration of road-related data systems to the project, while SAIC has contributed system integration experience and resources to the development of the product.

"This program brings the technical strengths of both SAIC and Meridian to bear on the critical information services required by highway operation and maintenance agencies," said Carl Bjerkaas, SAIC vice president for operations of the Command, Control, Communications, Computers and Information Technology Business Unit.

"As transportation agencies at all levels of government strive to make more informed decisions, they need to have the ability to integrate data and information from multiple sources. Our system provides a framework for bringing all required data and information into one location for those decisions makers," said Leon Osborne, president of Meridian Environmental Technology, Inc.
