Executive summary

  • There has been a massive increase in traffic in London since 2009
  • Virtually all this increase has materialised on minor roads (‘C’ and unclassified)
  • Croydon matches these trends
  • Traffic increases on specific rat-run roads are even more significant

DfT comment on above graph: “The traffic count data for a given location can be used to understand the trends for that specific minor road. However individual counts at minor road locations cannot be combined to produce a Local authority level. Traffic estimates for a local authority would need a larger sample size, and can’t be inferred from a limited number of raw minor road counts in that area.”

Local main roads

The data points marked ‘Manual count’ are from a typical day between 7am and 7pm. The remainder are estimated.

All data points except 2016 were manual counts on a single day between 7am and 7pm.


The Speedvisor is located near the entrance to Stambourne Woods on Auckland Road. It displays speed to drivers approaching from Anerley Hill (North East). It was installed temporarily in 2013, then permanently in 2019 after a serious crash. It can download raw data which can be used to derive traffic counts and speeds. This has been performed three times.

The Speedvisor has spectacularly failed to reduce speed. The record in January 2019 was 70mph.

Comparison of January 2013 with January 2019

Between 2013 and 2019, traffic increased over three-fold overall but by four times in the evening rush hour.


See Telraam traffic counters coming to Crystal Palace for more details about what these citizen monitoring devices are. There are currently 3 in operation locally:
