of Transit Signal Priority (TSP), a system that can extend green lights to allow buses to get through. The system can boost average speeds as much as 8% and is in use on several of the city's busiest corridors, including Aurora Avenue North, Rainier Avenue S and Lake City Way NE. The system uses RFID tags that are read as buses approach a TSP equipped intersection. In 1998, the fleet was updated with an Automatic Vehicle Location (AVL) system that utilizes battery-powered beacons that read the RFID tags and communicate the buses' location to Metro. In 2010, the AVL system was replaced with a GPS-based system as part of a system-wide radio update. As a part of the radio update Metro also added automated next stop signs and announcements to all buses. In 2010, Metro rolled out a new IP network based ITS infrastructure for its RapidRide service. Buses will communicate with roadside equipment using 802.11 wireless technology on the 4.9 GHz public safety band. A fiber optic backhaul connects access points and roadside equipment together to Metro's Communication Center. The system will extend the legacy RFID-based TSP system. It will also be used in conjunction with GPS technology to provide frequent and accurate location updates for next bus arrival signs at RapidRide stations. The extent of Metro's application of intelligent transportation systems (ITS) for transit information available for customers has been limited to a few projects: An early project called MyBus by the University of Washington (UW) utilized the tracking data to provide real-time bus information. This is now hosted by Metro under the name Tracker. An improved version of MyBus called OneBusAway, developed by UW graduate students Brian Ferris and Kari Watkins, combines Tracker information with Google Maps. OneBusAway continued to be maintained by the University of Washington Department of Computer Science, until a new nonprofit organization was founded to house and administer it in 2019. Transit Watch displays, like those found in airports and major train stations, are installed at some transit centers and transfer points to show real-time bus arrival information. A pilot project provided bus information displays along a city arterial. Metro discontinued the project in 2005, citing the cost of maintenance and technical problems. Metro has a regional trip planner that provides itineraries for transit trips within King, Pierce, and Snohomish counties, including those on Sound Transit services, Washington State Ferries, the Seattle Center
