A new study found a 35 percent drop in overall road injuries in one of London’s low-traffic neighborhoods (LTN), areas designed to prioritize people on bikes and on foot.

As Ron Johnson explains in Momentum, “the injury reduction inside LTNs was consistent across different user groups and locations, although the benefit was smaller in outer London LTNs introduced since 2020. Where LTNs were removed, injury levels rose back to pre-intervention rates.” According to the researchers, the LTNs prevented over 600 injuries during the study period.

Further, the analysis addressed a common criticism, that LTNs could potentially shift dangerous traffic to other streets, finding that cyclists and motorcyclists on boundary roads around LTNs also saw a decrease in injury rates.
