  1. 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.

  4. Johnson City MPO Background • Established: 1982 • Staff: 3 Full-Time Personnel • Housed with GIS and Public Transportation Staffs • Established: 1982 • Staff: 3 Full-Time Personnel • Housed with GIS and Public Transportation Staffs

  5. 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

  6. FTA Regional Mobility Research Projects: 1991 - 94

  7. Overall Design: Systems Integration Emphasis With GIS

  8. Traffic Signal Monitoring System: • Linked Through Fiber Optics • Based on Siemens/ACTRA • Links to Other Sensor Elements • GIS Links • Opticom • Variable Message Signs

  9. Video Monitoring

  10. Traffic Monitoring Sensors • Based upon Active Microwave Sensors (RTMS) • Multipurpose Functionality • GIS Links • Real Time Data for Traffic/Transit Managers • Mounted Overhead: Reduced Maintenance Costs

  11. Integration with Traffic Monitoring Sensors • Permanent and Mobile Locations • Traffic Signal Integration • Incident Detection and Management • TDOT Count Stations

  12. Transit/Paratransit Management • Routing/Scheduling: ADA Clients • Real-Time Monitoring/GPS • GIS Integration • Coordination Among Providers • Access to Real-Time Traffic Data

  13. Incident Management • Integration of ACTRA, RTMS, GIS, Real-Time Access • I-26 Importance • Links to TDOT

  14. Strategic Approach • GIS as the “Core”: Why? • Seamless Data Integration • Spatially-Based Information • Open Systems • Existing Tools, Easy-To-Use Interfaces • Customizable

  15. The “Integrating” Nature of Present-Day GIS • GIS in the Mainstream: • Data Integration • Delivery Mechanisms (Internet) • Improved Interfaces • Lower Cost • “Toolbox” Approach

  16. GIS-ITS Integration • GIS Elements: • ESRI, Intergraph Products • ArcView, ARC/INFO, MapObjects, GeoMedia ,Web Tools • Database Flexibility (Access, etc.) • Data Availability Locally • Relationships with TDOT (TransCAD modeling)

  17. GIS Base Data • Extensive Sources: • City has Long-Term GIS (15 Years) • Transit - 1 of the First Users of GIS • High-Quality Transportation Data • Recent Digital Orthos, Planimetrics • Tested Data Exchange with TDOT • Section 15 Data • Development of Custom Interfaces for Users

  18. Internet/Visualization/ATIS: • Public Access • GIS/Web Tools • 3-D Visualization Tools • Real-Time Data Display and Query • Future Bandwidth: Internet 2 • Kiosks or Publicly Accessible Computer Terminals for Transit

  20. Potential for Vehicle Tracking On Web

  21. ITS National/Regional Architecture • Purpose: Promotes ITS Integration Nationally and Regionally • Provides a Framework, Standardized Approach for Development • Adaptable and Customizable “Integration Strategy”

  22. ITS National/Regional Architecture

  23. Customize Architecture to Fit Your Needs/Situation

  24. GIS Summary/Significance • GIS As a Central, Integrating Technology • Mainstream Maturity of GIS • High-Tech, Leading Edge Possible in Smaller Areas • For MPOs & Transit Systems…. • Many Possibilities
