2022 Healthy Streets Scorecard results
Hounslow has improved its position on Low Traffic Neighbourhoods (LTNs) – in 2020 it had 19% of LTNs as a proportion of total area appropriate for LTNs, and now has 31%, School Streets (now has 30% of schools with School Streets as a proportion of all borough schools, up from 27% last year) and School STARs (10% increase from 2021) and as a result has moved up the overall table from position 21 to 20, so is to be congratulated.
It still has a huge amount of work to do, though. It could improve its score relatively quickly by expanding coverage of 20mph speed limits and introducing more Controlled Parking Zones (CPZ) to better reflect the negative impacts of free and unrestricted parking. We were unable to update this year however Hounslow told us they introduced seven new CPZs since 2020, which is great news and we hope they will introduce even more in the coming year. Improvements will be reflected in next year’s scores.
We also want to see more LTNs and School Streets as well as action on polluting cars – Hounslow has a very high proportion of polluting cars with the second highest proportion of diesel cars compared to all other boroughs at 29% (Greater London average is 24% and borough-lead Camden has 17%).
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.
