2022 Healthy Streets Scorecard results

Sutton is 28th of 33 London local authorities in this year’s Scorecard and so remains in the same position as last year, lingering at the bottom of the table. 

There has been little progress in Sutton to make streets healthier. Sutton has advised they have over 10 School Streets (where we reported they had zero in 2022), where traffic is restricted around schools at arrival and departure times, after removing all the schemes it implemented in 2021. Sutton has just 9% of the borough’s streets in a Low Traffic Neighbourhood (LTN) compared to leading Outer London borough Waltham Forest at 47%. 

Just 24% of borough-managed roads have 20mph speed limits whereas 17 boroughs have over 80% and many have them borough-wide. Sutton has below 10% of borough-managed roads under some form of Controlled Parking Zone.

Car ownership rates are among the highest in London with 104 cars per 100 households, this compared to leading Outer London borough Greenwich with 69 cars registered per 100 households.

Sutton needs to make a start on implementing all measures – LTNs, 20mph speed limits, controlled parking, protected cycle lane and more School Streets – or it will stay bottom of the table with some of the unhealthiest streets in London.

The Healthy Streets Scorecard combine scores for nine indicators to create an overall Healthy Streets score for each borough. See the graph below for 2022 results (includes 2019 – 2021 results for comparison). For more detail visit the London-wide overview of the 2022 results. You can also:

Scorecard (factored score) chart explained

In the chart above, each borough has been given a factored score. Factor scores are composite variables which provide information about a borough’s placement on a scale. Factor scores are given by F=XB, where X is the indicator normalised score for a borough and B is the factor score coefficient (or weight). Each indicator is weighted as 1, or 0.5 if there are two parts to one indicator, for example Modeshare has a weighting of 1, Active travel – walking has a weighting of 0.5 and Active travel – cycling has a weighting of 0.5. The borough’s total factored score is the sum of all indicator factored scores which is then factored to 10 (multiplied by the number of indicators/10) to give a value on the scale between zero and 10. We can then compare boroughs against each other on the scale.
