Low-traffic neighbourhoods cut road injuries and deaths by more than a third within their boundaries with no apparent negative safety effect on nearby roads, a study has shown.

Based on comparisons of more than a decade of road casualty statistics between 113 London LTNs and other roads that did not have them, the report’s authors found that LTNs were associated with a 35% reduction in all injuries, rising to 37% for deaths and serious injuries.

In absolute terms, the study concluded, this meant that creating the LTNs prevented more than 600 road injuries that would have otherwise taken place, including 100 involving death or serious injury.

On boundary roads, those just outside the LTNs, there was no observable change in the number of casualties.
