Impacts of 2020 Low Traffic Neighbourhoods in London on Road Traffic Injuries

We assessed the impacts of Low Traffic Neighbourhoods (LTNs) implemented in 2020 on road traffic injuries. We used police data from October-December 2018/2019 (pre) compared with the same period in 2020 (post). We found absolute numbers of injuries inside LTNs halved relative to the rest of London (ratio 0.51, p<0.001). Considering changes in background travel patterns, our results indicate substantial reductions in pedestrian injury risk. Risks to other road users may also have fallen, but by a more modest amount. We found no evidence of changes in injury numbers or risk on LTN boundary roads.
