  1. Center to Center (C2C) Regional Signal Interoperability Using the Traffic Buster Network Michael Forbis, P.E. ITS Engineer Northwest Region Traffic Operations Paula Hammond Secretary of Transportation Steve Reinmuth Chief of Staff ITE Washington State Section November 12, 2008

  2. Traffic BusterOverview • Connects agencies with “free” network • Shares video between agencies • Stores agreements and emergency plans • Provides the backbone for sharing traffic signal control

  3. Traffic Buster Project Goals • Use WSDOT ITS network to connect agencies • Equipment to share agency cameras • Provide network for C2C traffic signal system communications • Website for agreements and contacts

  4. Traffic Buster Fiber Cable Plant 22 Agencies Connected 24 to 96 fibers Traffic Buster adds 12 additional agencies for a total of 22 Digital Network (2.4 Gigabit) • Ethernet to connect central systems • Streaming Video to monitors and computers • Expandable to meet the region’s needs

  5. Everett Snohomish Co. Federal Way SeaTac Des Moines Kirkland Edmonds Lake Forest Park Seattle Bellevue Issaquah Mountlake Terrace King Co. EOC Snohomish Co. EOC Community Transit Tukwila Kent Redmond Auburn Lynnwood King County Renton Traffic Buster Agencies Connected

  6. Traffic Buster System Architecture • Access to 1 gigabit synchronous backbone • 100 megabit agency connection to the backbone • Private network with a sub-network for agency use • Share Cameras 10 at a time (MPEG4 encoders) • See cameras 4 at a time (MPEG4 Decoders ) • PC terminal and software as needed • IP network for C2C connections

  7. Traffic BusterPhases 1 and 2 Phase 1: -regional network - camera coordinationPhase 2: - regional data collection - signal coordination - incident management plans

  8. Traffic Buster Center to Center Communication

  9. Traffic Buster Time Based Signal Coordination

  10. Traffic Buster Traffic Responsive Signal Coordination

  11. Traffic Buster Traffic Responsive Signal Coordination Central Database: • VOS from system loops • Greens from all or just key signals • Current pattern, cycle, split, offset, ped phase • Preemption status • Bus priority status from signals and KC Metro • Signal clock data • On-ramp and freeway VOS data

  12. Traffic Buster One Agency Operating

  13. Traffic Buster Signals Connected to Network

  14. Traffic Buster AWV Mitigation and ICMSeattle Area Transportation Management Systems Data Exchange and Joint Operation • C2C for TACTICS (Seattle) • C2C for I2TMS (WSDOT, KC) • C2C for WSDOT Freeway System • C2C for KC Metro and ST Data (Phase 2) • Central Database for Performance Data • Connect Seattle, WSDOT, KC, and UW
