Traffic

Traffic data, analysis and feedback.

Collecting traffic data is a crucial element of our monitoring process that reveals key insights into how the LTN is working towards its objectives. Data has been collected inside LTN areas as well as on the immediate boundary roads that surround them at three separate stages of assessment.

  • Stage 1 data and analysis was published in February 2021 and is available at this link .
  • Stage 2 data and analysis is published below

Headlines SYSTRA Stage 2 Monitoring:

The total volume of motor vehicles counted on streets within the LTN has decreased by 54% , but increased by 13% on boundary roads.

  • Traffic on streets within the LTN and on boundary roads combined decreased by 5% , around 6,000 vehicles a day.
  • Across all streets, the volume of HGVs has decreased by 22% whilst the volume of LGVs has decreased by 14% .
  • The volume of motorcycles on internal streets has increased by 80%  and increased by 89% on external streets, with a 85% change overall.
  • Through traffic has reduced significantly on streets within the Low Traffic Neighbourhood.

Note that the increase in motorcycles, although high in percentage terms, is generally low in absolute terms.

Data gathered through the enforcement cameras show that about 90% of penalty charge notices come from people who live outside of the scheme, with the highest proportion of them living outside of Lambeth.

Instances of penalty charge notices has significantly dropped since the scheme began which indicates that people are not routinely noncomplying.

Through the analysis of bus journey time data provided by TfL, there is no indication that bus journey times have significantly increased on boundary roads due to the LTNs, but where bus routes pass through the LTN - such as Downton Ave (P13) - we have seen an improvement in bus journey times.

Since the start of the stage 2 feedback collecting period in January 2021, we have received 215 traffic related emails.

Benefits noted:

  • A noticeable reduction in traffic speeds and volumes along Hillside Road
  • Less aggressive traffic and less rat running
  • Reduction in traffic noise within the LTN
  • Quieter streets considered more pleasant and safer

Concerns noted:

  • An increase in vehicle traffic on boundary roads
  • Roads of concern – for varying reasons - included Leigham Court Road, Leigham Vale, Christchurch Road (the South Circular), Mount Nod Road, and Hailsham Avenue
  • Respondents noted that traffic volumes and flows had been impacted negatively by ongoing road works
  • Stakeholders frequently mentioned short journeys taking longer
  • Quieter, car-free streets feel less safe to some
  • ABCD streets were wide enough to accommodate two-way traffic


Further Changes: Leigham Vale

Stakeholders have raised issues such as increased congestion, speeding, inadequate carriageway width leading to aggressive driving of vehicles, and safety concerns.

We are currently developing options for this location to address the issues raised by residents. These proposals will be shared with stakeholders in the coming months.

Leigham Court Road

We are exploring potential actions to take to improve traffic flow and calm traffic, both of which are issues raised through correspondence.
