  1. SCATS Adaptive Traffic System TRB Adaptive Traffic Control Workshop January 2000 Session 2 - Equipment Requirements For further information contact: Neil R. Gross Neil.Gross@transcore.com

  2. SCATS Architecture

  3. SCATS System ArchitectureMinimal System - Single Region

  4. SCATS System ArchitectureSCATS 1 - with Integration Server

  5. Configuration - SCATS2

  6. SCATS Sensors • Controller collects number of spaces and total space time during green of each movement, each cycle for use by SCATS adaptive algorithm. • Actual movement data collected by stop line detectors allows accurate split determination.

  7. SCATS Sensors • Loop Detectors or equivalent (video detection in Oakland County MI) in most lanes at the stop line. • Some lanes can be left without detectors.

  8. Communications - SCATS1

  9. Communications - SCATS2

  10. AWA Delta 170 upgrades existing 170 controller to support SCATS. Relay Module added for sense/control of cabinet status. AWA Delta 3N controller replaces existing NEMA controller. Connections are via existing A, B and C connectors. One back-panel link required. SCATS Traffic Controllers -Existing 170 NEMA

  11. SCATS 2070 SCATS 2070N SCATS Traffic Controllers -Planned

  12. SCATS Hardware Requirements • Management Computer - Database and Mgt Systems • SCATS 1 DEC VAX/ALPHA, OpenVMS • SCATS 2 Networked PCs • Regional Computer - Strategic Control • Personal Computer with Windows NT • Digi Serial Interface system.

  13. SCATS Hardware Requirements • Operator Workstations - Up to 15 • Personal Computer with Windows NT or Windows 98 • SCATS Controllers - Tactical Control • up to 250 per Regional Computer

  14. SCATS Installation Cost Ranges 64 Intersection System • Central Hardware approx. $ 30,000 (small VAX) • Central Software approx. $40K to $70K • Regional Hardware approx $20K • Regional Software approx $70K

  15. SCATS Installation Cost Ranges 64 Intersection System • Local Controllers approx. $3.5K to 5.5K, total say $300K • Communication Network - Included above • Detection Sensors …. Standard loop amplifiers and 6 x 15 loops…..$230K? • Total - approx $650K for single Regional (No CMS)

  16. SCATS Operations & Maintenance Cost Ranges - 64 Intersection System • Central Hardware approx $3K per annum • Central Software approx $4K per annum • Regional Hardware - negligible. • Regional Software approx $8Kpa • Regional Setup & Support - similar to current support level plus quarter to half man year per annum.

  17. SCATS Operations & Maintenance Cost Ranges - 64 Intersection System • Local Controllers - similar to current controllers • Communication Network - User owned TWP? or VG Leased Line approx $22/month • Detection Sensors …loop maintenance? Depends on quality of original installation and road surface...

  18. End Thank You
