Road Safety Campaigns Linked to Reduction in Injuries

a study from London showed that introducing low‑traffic zones (LTNs) — an urban road‑safety measure — was associated with a 35% reduction in all road injuries and a 37% drop in deaths and serious injuries within the zones, compared with control roads.
In Kenya, a behaviour‑change intervention targeting public minibuses (matatus) saw promising results. A study found that placing evocative safety‑messages inside ~12,000 matatus led to a 25–33% reduction in insurance claims, and was associated with an estimated 140 fewer road accidents per year, compared with predictions.
Broad, evidence‑based road safety measures — such as reducing speeding, enforcing helmet and seat‑belt laws, and improving drunk‑driving enforcement — have been shown globally to have major impact. A recent meta‑analysis indicates that such interventions could prevent 25%–40% of all fatal road injuries worldwide.
These examples show that road‑safety campaigns — whether through urban design, public‑transport behavioural nudges, or policy enforcement — can meaningfully reduce injuries and fatalities. If you like, I can gather 5–10 recent examples from Africa and around the world illustrating this — so you can see the diversity of effective interventions.
