What are Intelligent Transportation Systems ITS The application

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.

Current Technology Innovation Larger storage Voice/ writing input Cheaper Faster processors High-quality video and graphics Smart cards Flat, highresolution screens

Future Wide Area Bandwidth Generation Speed Technology Application 33. 3 56. 0 Modem, ISDN Text great, Pictures OK Midband 100 -400 ISDN, PC cable modem Pictures great, Video OK Broadband 1500+ Internet 2 Video great (k-baud/sec. ) Narrowband (Today) (1 -2 years) (2+ years)

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 v Identify larger statewide ITS initiatives for “mainstreaming” and tests v Emphasize “practical side” of ITS (Internet, GIS, lower cost sensors, etc. ) v Software Integration v Focus on SR 381 Medical Corridor and New Interstate 26 Extension to Asheville, NC v

FTA Regional Mobility Research Projects: 1991 - 94

Overall Design: Systems Integration Emphasis With GIS

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

Video Monitoring

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

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

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

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

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

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

GIS-ITS Integration • GIS Elements: v ESRI, Intergraph Products q. Arc. View, ARC/INFO, Map. Objects, Geo. Media , Web Tools v Database Flexibility (Access, etc. ) v Data Availability Locally v Relationships with TDOT (Trans. CAD modeling)

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

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