Data: Monitoring and Consultation


Data: monitoring and consultation

Oval LTN has followed Lambeth’s LTN monitoring strategy and gone through two stages of monitoring and a public consultation. We know changes to roads take time to settle in, so we need to monitor in stages to see how travel behavior changes over time. 

The monitoring considered traffic counts, air quality, public transport and emergency service journey times and community feedback. The stages are outlined below:

Temporary Traffic Order:

  • Stage 1 Monitoring

Experimental Traffic Order:

  • Objection period (6 months)
  • Stage 2 Monitoring 
  • Consultation (5 weeks)

Permanent Traffic Order:

  • Stage 3 Monitoring
  • Filter design engagement

The primary objective of the scheme was to achieve a reduction in traffic considering both roads within and the boundaries of the area. 

 The results of the monitoring are outlined here:

Stage 1 - Oval to Stockwell

Stage 2 - Oval to Stockwell

 Monitoring Summary:

  • 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.


The consultation was open to any organisation and any member of the public who wished to provide a response. The primary response channels available during the consultation were:

  • An online survey (residents could request a paper copy with free post return envelope)
  • Telephone surveys undertaken by a market research agency with a representative sample of residents living within the area
  • Email correspondence
  • Council staff being available on-street to help residents and visitors to the area complete the survey on tablet, provide paper copies of the survey, or answer quick questions. 
  • Street audits with disabled people, run by Transport for All (a pan-disability, mobility charity)
  • Street activation events to gather feedback on permanent space ideas.


  • Online consultation survey form: 3395 
  • Representative telephone polling: 211 
  • Email correspondences: 256

Total: 3862
