What are Intelligent
Transportation Systems (ITS) ?


The application of advanced sensor, computer,
electronics, and communications
technologies

and management
strategies



in an
integrated

manner


providing traveler
information

-

to increase the safety and
efficiency of the surface transportation system.

Johnson City Project Scale


ITS “Lite”


Urban Metro Setting < 200,000 population


Identify larger statewide ITS initiatives for
“mainstreaming” and tests


Emphasize “practical side” of ITS


(Internet, GIS, lower cost sensors, etc.)


Software Integration


Focus on SR 381 Medical Corridor and New
Interstate 26 Extension to Asheville, NC


FTA Regional Mobility
Research Projects: 1991
