King County MetroTransit ITS Overview of the King County Metro Transit Intelligent Transportation Systems
Metro ITS Projects • Communication Center • Transit Radio System • On-Board Systems • RapidRide ITS
Communications Center • Enhanced computer-aided-dispatch and AVL, over legacy system • Text messaging reduces voice traffic • Automated headway management tools to support RapidRide
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
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
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)
