Oval to Stockwell Low Traffic Neighbourhood Stage Two Monitoring Report

A report on the impact of the Oval to Stockwell low traffic neighbourhood. This stage two report is part of our continuous monitoring of the scheme.

We’re asking people who live, work and travel in the Oval to Stockwell trial low traffic neighbourhood (LTN) to share their views by doing a survey. This is because we’re considering making the changes permanent after monitoring the LTN and finding that it has been reducing traffic in the area.

We put in LTNs, which use measures such as traffic filters, to help reduce motor vehicle traffic. With less traffic we aim to improve road safety for all users, encourage travel in more active and healthy ways, support the local economy and make streets nicer places to be, reduce air pollution and improve air quality.

LTNs were recommended in our long-term transport strategy agreed in 2019. They were introduced more quickly than planned because of Covid-19.

Impact of the LTN so far

We’ve been keeping track of traffic, air quality and cycling in the Oval to Stockwell LTN, and here’s what we’ve found out: 

  • Motor vehicle traffic fell by a quarter inside the LTN and by 8 per cent when including boundary roads. 
  • The largest reduction on a boundary road was 1,300 vehicles a day on Clapham Road. 
  • Traffic did not reduce much on Harleyford Road and increased 3 per cent on South Lambeth Road.
  • Cycling increased by 87 per cent, with increases in cycling seen at 12 of the 15 monitoring locations.
  • Traffic has reduced on a further five streets in the area by enough to be added to our ‘Healthy Routes Network’, which means we class them safe enough for a 12-year-old to cycle independently.
  • The LTN has had some impact on air quality and we expect to see more substantial changes over time.
  • Reductions in nitrogen dioxide are five times greater in London than elsewhere in the UK, partly due to measures such as the Ultra-Low Emission Zone.
  • All the places where we analysed air quality that were classed as sensitive, such as outside schools and care homes, had air quality within legal air quality limits.

Improving the LTN

We know that some car journeys are hard to avoid and that the LTN will not solve all traffic issues in the area. Therefore we’ve come up with changes to the LTN that we think will help it work well for everyone if it stays in place.

  • Ability to apply for an exemption from one traffic filter for blue badge holders.
  • Ability to apply for an exemption from bus gates within LTNs for taxis and fully accessible private hire vehicles.
  • Rapid response healthcare providers to be exempt from all filters. Emergency services are already exempt.
  • Accessibility improvements to pavements, kerbs and roads spotted through audits and resident feedback.
  • Seating and planting outside businesses to encourage more visitors.
  • Review of road layouts to increase bus priority and walking and cycling access.
  • Review of traffic signal timings and putting back movement bans at junctions where possible. 
  • Further changes to specific roads such as Lansdowne Way.
  • Support installation of ‘green screens’ to combat pollution on busy roads for buildings such as schools.

Across the borough we’re also planning activities to support people to walk, cycle and use public transport instead of private motor vehicles. We’re also introducing ultra-low emission vehicles and bikes for council operations.
