All four Oxford hospitals can be reached by car without entering a traffic-filter zone, according to the available travel arrangements.
Drivers are not required to hold a traffic filter permit when travelling to John Radcliffe, Churchill, Warneford or Nuffield hospitals, all of which lie within the ring road.
A route around the ring road provides access to the hospital sites.
Cyclists, van users and motorcyclists are also permitted to travel through traffic filters, giving them an alternative approach to the hospitals.
Public transport provides several options for reaching the same destinations.
Services 600, 700, H2 and X32 call at, or close to, John Radcliffe, Churchill and Nuffield hospitals.
The 600 and H2 services originate at Thornhill Park and Ride, with as many as four journeys each hour.
The 700 operates from Oxford Parkway Park and Ride at intervals of up to three services per hour, while the X32 from Redbridge Park and Ride runs up to six times hourly.
Warneford Hospital is served by the H2, 600 and 700 services.
Travellers departing from Thornhill Park and Ride can board the H2 or 600, with up to four buses each hour, or take the 700 from Oxford Parkway Park and Ride, where up to three buses per hour are available.
The 400 service, also departing from Thornhill Park and Ride, calls near John Radcliffe, Nuffield and Warneford hospitals.
It runs up to six times per hour, and passengers face an approximately 10-minute walk from the stop to the hospital.
A joint car-park and bus ticket is priced at £3.
It can be obtained from the car-park ticket machine or through the RingGo app by choosing the Parking & Bus option.
Either the parking ticket or an active RingGo session may be shown to the bus driver.
