and in 2005 FirstGroup was fined for delays and safety violations. Although the city council has included a light rail system in its local transport plan since 2000, it has not yet funded the project; Bristol was offered European Union funding for the system, but the Department for Transport did not provide the required additional funding. As of 2019, a four-line mass transit network with potential underground sections radiating from Bristol Temple Meads is proposed; a southern line to Bristol Airport, a northern line to Aztec West, a northeastern line Bristol & Bath Science Park and a southeastern line to Brislington or Keynsham. In 2006, a project to develop a bus rapid transit system (BRT) named MetroBus was started, with the purpose of providing a faster and more reliable service than buses, improving transport infrastructure and reducing congestion. The project was approved by the government in December 2013, and in June 2017, it was announced that First would operate the buses. MetroBus services commenced in 2018, with the opening of a route from Emersons Green to Bristol City Centre (route m3). Further routes were subsequently introduced from Cribbs Causeway to Hengrove Park (route m1), and from Long Ashton Park and Ride to Bristol City Centre (route m2). In May 2022, it was announced that a fourth route would open in Spring the following year to connect Cribbs Causeway with Bristol Parkway Railway Station (route m4). Three park and ride sites serve Bristol. The city centre has water transport operated by Bristol Ferry Boats, Bristol Packet Boat Trips and Number Seven Boat Trips, providing leisure and commuter service in the harbour. Cycling Bristol was designated as England's first "cycling city" in 2008 and one of England's 12 "Cycling demonstration" areas. It is home to Sustrans, the sustainable transport charity. The Bristol and Bath Railway Path links it to Bath, and was the first part of the National Cycle Network. The city also has urban cycle routes and links with National Cycle Network routes to The rest of the Country. Cycling trips increased by 21% from 2001 to 2005. Air The runway, terminal and other facilities at Bristol Airport (BRS), Lulsgate, have been upgraded since 2001.
