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 MPO Background
• Established: 1982
• Staff: 3 Full-Time Personnel
• Housed with GIS and Public Transportation
Staffs
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 - 94
