2021 Healthy Streets Scorecard results

Merton has the second highest score of all Outer London boroughs and its stand-out result is that 41% of its schools now a School Street, where traffic is restricted at arrival and departure times, which is the highest rate of any London borough.

It also now has a 20mph speed limit on nearly all its streets which makes it the leading Outer London borough on this indicator. And it scores well on Low Traffic Neighbourhoods (LTNs) with 34% of suitable streets in an LTN (a good score though lower than leaders Hackney 55% and Waltham Forest 47%) and while it must be congratulated for introducing some new LTNs, most are historic and more could have been done in the past year.

Overall Merton sits mid-table and still has some way to go to catch up with the best performing Outer London borough Waltham Forest and to meet the Mayor’s Healthy Streets targets.

Merton also has very low numbers of protected cycle lanes compared to other boroughs, with just 3% of roads covered compared to leaders City of London with 21% covered. This is clearly an area for action. It also has low rates of controlled parking. Just 33% of Merton’s roads have controlled parking (compared to 9 boroughs where over 87% of roads have controlled parking, five of them with 100% coverage).

A third of Merton households don’t own a car so there is a need, as well as an opportunity and obligation, to do more to enable people to travel sustainably.

The Healthy Streets Scorecard combine scores for nine indicators to create an overall Healthy Streets score for each borough. See the graph below for 2021 results (includes 2020 and 2019 results for comparison). For more detail visit the London-wide overview of the 2021 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.
