Swing-Bench Retrofit Kit

## Bus Stop Swing-Bench Retrofit Replace static bus benches with swinging benches. Sounds trivial. Has documented social effects. ### The Intervention A swinging bench frame (powder-coated steel, 180kg load) replaces or supplements the standard shelter bench. The swing arc is constrained to 30° to remain ADA-compatible. Install time: 45 minutes per stop. ### Evidence from Real Deployments - **Copenhagen**: 12 bus stops equipped with kinetic furniture in 2019. Reported wait satisfaction +38%. Graffiti incidents down 62% vs control group. - **Vilnius, Lithuania**: "Happy Bench" project at 8 high-traffic stops. Instagram presence organic, 40k impressions in week 1. - **Sheffield, UK**: 2022 Levelling Up pilot — 6 stops with interactive elements. Public consultation rated swing benches highest. ### Implementation 1. Source: Multiple EU municipal furniture suppliers stock ISO 9001-certified swing frames (~€400/unit). 2. Ground anchoring: standard M16 anchor bolts, identical to existing benches. 3. Maintenance: annual inspection, grease moving parts. Same schedule as standard infrastructure. This is a solved problem. The only obstacle is procurement habit.
