  1. King County MetroTransit ITS Overview of the King County Metro Transit Intelligent Transportation Systems

  2. Metro ITS Projects • Communication Center • Transit Radio System • On-Board Systems • RapidRide ITS

  3. Communications Center • Enhanced computer-aided-dispatch and AVL, over legacy system • Text messaging reduces voice traffic • Automated headway management tools to support RapidRide

  4. 700 MHz Radio System • Integrated voice & data system • 4 FDMA slotted data channels, 1 control channel • 6 two-slot TDMA voice channels (12 voice paths) • 7 tower sites, 1 in Downtown Seattle Transit Tunnel

  5. On-Board Systems • Life cycle replacement and upgrades • Voice and data communications • “Smart bus” functionality • Multiple layers of integration • Single driver display for all functions • Multiple uses for wireless networks • Designed for evolution • GPS for enhanced AVL accuracy • Automated stop announcements & signs • Integrated passenger counting • “Lateness and load” data for TSP system

  6. RapidRide ITS Elements • Wireless Transit Signal Priority (TSP) • Real-Time Passenger Information • Off-board fare collection • High-bandwidth AVL • Multi-purpose ITS Network (4.9GHz)

  8. Wireless TSP • Extension of existing TSP system • IP message replaces RFID tag • Wireless vehicle-to-roadside comm. • Multi-purpose ITS Network for roadside interconnect and backhaul

  9. ‘Tech Pylon’ • Next bus arrival sign, enhanced by frequent bus location updates • Off-board fare transactions • Wireless “last-mile” communications • ITS Network for roadside interconnect and backhaul

  10. ITS Network • IP/Ethernet based network • Fiber optic infrastructure • Wireless mobile and “last mile” communications (4.9GHz) • Backhaul services through partnerships

  11. King County Metro ITSBusiness Impacts • Communication Center:Improved transit system information and management. • Transit Radio System:Modernization and FCC compliance. • On-Board Systems:Integration and modernization. • RapidRide ITS:Improved efficiency and passenger services.
