Oxford traffic filters: gridlock reported across city centre

Oxford traffic filters gridlock has been reported by shoppers, taxi drivers and bus operators since the county council’s trial began, according to the BBC. At the weekend there were reports of standstill traffic in and around Botley Road and Oxpens Road, and at the entrance to the Westgate shopping centre car park. The picture is not simple, because roadworks in the same area are also affecting traffic.

What the Oxford city centre congestion filters change

On 28 September the £5 daily congestion fee to drive past six points around Oxford was replaced by a fine of up to £70, as part of the Oxfordshire County Council traffic filters trial, the BBC reported. The six points are on Thames Street, Hythe Bridge Street, St Cross Road, St Clement’s Street, Marston Ferry Road and Hollow Way. The filters use the same technology as the earlier temporary charge, including automatic number plate recognition cameras.

Four of the points operate seven days a week from 07:00 to 19:00. The two on Marston Ferry Road and Hollow Way work only at peak times, between 07:00 and 09:00 and between 15:00 and 18:00, Monday to Saturday.

The filters were first approved by the county council in November 2022, then postponed because of the long-delayed Botley Road works. A six-month public consultation is now under way and the trial can run for up to 18 months. Gareth Epps, the council’s transport chief, said: “The traffic filter trial is the next step in helping us tackle congestion that has blighted the city for decades.” The council says it is still early days and that it is monitoring the impact carefully.

Who pays more, and who is affected most

The change moves from a modest daily fee to a much larger penalty. The figures below are as reported by the BBC.

Oxford residents are eligible for 100 permits a year, which let them pass the points without a penalty. Under the 2025 charge proposals, people living elsewhere in Oxfordshire were to receive 25, while carers, traders and blue badge holders were to be exempt. Earlier 2022 plans also exempted buses, coaches, vans, lorries and emergency vehicles.

The pressure is falling on those stuck in the queues as much as on those fined. Taxi driver Mohammad Dil Pazir, who holds a permit and welcomes the filters overall, said the return journey to the railway station “could take us up to one hour… because it is gridlock. You cannot move.” Luke Marion of the Oxford Bus Company said there had been “quite significant queues” in the afternoon peak and on weekend afternoons, which he linked to traffic coming down Botley Road. He added that it is hard to judge the filters’ effect because of the roadworks.

Westgate Oxford said the scheme had the potential to harm the city centre and local businesses unless there is significant investment in public transport. It said that in severe congestion it had offered water to people stuck in its car park, including on Sunday after the Oxford Half Marathon.

A worked example: what the numbers mean in practice

Take a driver without a permit who is caught by a camera. The BBC reports a fine of up to £70, cut to £35 if paid within 21 days. Prompt payment saves £35, but even £35 is seven times the old £5 daily charge, and the full £70 is 14 times higher.

Now take a resident with 100 permits. If one permit covers one day, as the 2022 proposals described a 100-day pass, that is just under two days a week across a year. Someone driving through a filter five days a week for 52 weeks would need 260 days, so they would run out well before the year ended. That calculation is ours and rests on the one-permit-per-day assumption, which the sources do not confirm.

The cost of delay can matter as much as the fine. Mr Dil Pazir described a fare to St Aldates as “only about a £6 job”, but said the return was “costing us more money in fuel when we are stuck in the traffic, and time wise we are losing literally one hour for £6”. On his own account, that is £6 for an hour before fuel is counted.

What to do now

First, check your route before you travel. Councillor Andrew Gant, then the council’s traffic chief, said during the earlier 2025 proposals that it would be “perfectly possible to drive to almost everywhere in Oxford without passing a filter point”. Remember the hours: four points run from 07:00 to 19:00 every day, and two apply only at weekday and Saturday peaks.

Second, if you are eligible for permits, keep a note of how many you have used. If you do receive a penalty charge notice, the BBC reports the reduced rate applies if you pay within 21 days, so check the date on the notice rather than leaving it.

Third, if you were charged for driving on 27 September, do not assume the notice is valid. Oxfordshire County Council said it was investigating a supplier technical issue affecting some congestion charge permits that day, which it said had resulted in some people receiving notices incorrectly. It said it would contact those affected directly. Driver Rachel Griffin told the BBC she found more than 30 people reporting the same problem on social media. Finally, you can respond to the six-month consultation, which the council says is open.

Your questions answered

What are traffic filters?

Traffic filters stop drivers without permits from using certain busy routes. The BBC describes the Oxford version as using automatic number plate recognition cameras to issue penalties to vehicles that pass through without a permit. In Oxford they have replaced a temporary £5 daily congestion charge at the same six locations.

Where are the filter points in Oxford?

The filter points are on Thames Street, Hythe Bridge Street, St Cross Road, St Clement’s Street, Marston Ferry Road and Hollow Way. Check the county council’s own information for any other traffic restrictions.

Are the filters causing the gridlock?

That is not yet clear. Shoppers and drivers have complained of delays since the trial began, and Westgate Oxford says the scheme could harm the city centre without significant investment in public transport. But the Oxford Bus Company’s Luke Marion said roadworks in the area make it hard to judge. The council says it is monitoring the trial.
