Traffic filter trial to start in Oxford on 28 September

Residents are being encouraged to check their eligibility for a permit to travel through Oxford’s traffic filters ahead of the trial starting on 28 September.

Oxfordshire County Council’s temporary congestion charge will be replaced by the traffic filter trial on 28 September as the council continues its work to tackle congestion, improve bus reliability and support sustainable travel across the city.

For most people who already hold a temporary congestion charge permit, there is no need to take any action as their permit will automatically transfer to the traffic filter scheme. However, Oxfordshire residents, businesses and organisations that do not currently hold a permit are being encouraged to check their eligibility and apply before the trial begins.

Councillor Gareth Epps, Oxfordshire County Council's Cabinet Member for Transport Management, said: "If you don't currently have a permit and think you may be eligible, now is the time to check and apply. Taking action now will help ensure a smooth transition when the trial begins on 28 September."

Applications can be made online. Residents in the Oxford permit area are eligible for 100 free day passes per year, while residents in the Oxfordshire permit area are eligible for 25 free day passes per year.

The traffic filter trial was approved by Oxfordshire County Council’s cabinet in November 2022 following a public consultation.

The temporary congestion charge was introduced in October 2025 as an interim measure while the Botley Road closure prevented the planned introduction of traffic filters. Monitoring data published monthly shows a number of encouraging trends.

Use of Oxford's park and ride network has increased significantly since the congestion charge was introduced. The most recent data for July 2026 shows that usage was up by 44 per cent at Redbridge, 33 per cent at Oxford Parkway and 31 per cent at Seacourt compared with the previous year.

Oxford Bus Company has reported around 41,000 additional passenger journeys per week across Oxfordshire compared with the same period last year, representing approximately 12 per cent growth. Around 17,450 of those journeys each week are linked to increased park and ride use.

The council's monitoring has recorded consistently lower traffic volumes on a number of key routes into Oxford, including Magdalen Bridge, Folly Bridge and Abingdon Road, which showed reductions of 8 per cent, 12 per cent and 5 per cent respectively in June 2026. At the same time, some outer and ring-road sections are experiencing increased traffic or longer journeys, such as the sections between Cutteslowe roundabout and Wolvercote roundabout, Headington and Marsh Lane, and the southern ring road around Kennington, Heyford Hill and Hinksey Hill.

More than 129,000 permits have been issued since the temporary congestion charge was introduced.

Councillor Epps added: "The experience of the temporary congestion charge has shown encouraging signs that people are changing how they travel and that traffic and journey times have improved on many routes into central Oxford. We have seen strong growth in park and ride use, significant increases in bus patronage and improvements in journey times on a number of key routes into the city.

"The traffic filter trial is the next step in helping us tackle congestion that has blighted the city for decades.

“A six-month public consultation will open on 28 September. Feedback from residents and businesses will help us shape our future plans. We are listening and learning as we develop the best long-term solution for traffic in and around Oxford.”

About the traffic filter trial

• The traffic filter trial will operate in a similar way to the temporary congestion charge, with the filters being at the same six locations and a permit scheme in place. The trial, under an experimental traffic regulation order, can last for up to a maximum of 18 months.
• The key difference is that, from 28 September, car drivers will no longer be able to pay the £5 congestion charge to go through the traffic filters. However, with Botley Road open, everywhere in Oxford will be accessible by car at all times without driving through a traffic filter. You may need to take an alternative route, but often you won’t.
• Cars with valid permits and all other vehicles can travel through the filters at all times.
• At each traffic filter site, automatic number plate recognition (ANPR) cameras will monitor and enforce the restrictions. There will be no physical barriers. Cars without a valid permit driving through the filters will receive a fine of £70 (reduced to £35 if paid within 21 days).
• During the first six months of the traffic filter trial, the council will send a warning notice the first time any car goes through a traffic filter without using a permit, instead of sending a penalty charge notice.
• The scheme only applies to cars. All other vehicles are exempt. For those where car use is essential, there are 20 different types of permits e.g. for carers and community health and care workers, making travel around the city easier for these groups.
