30 km/h orari invece di 50 per ridurre drasticamente il rumore e aumentare la qualità di vita dei cittadini. Il chiasso, si sa, nuoce alla salute. Lo stress generato da anni di esposizione a un elevato inquinamento fonico può avere conseguenze fatali. Ogni anno in Svizzera circa 500 morti per malattia cardiovascolari e circa 2500 morti per diabete sono attribuiti all'elevato inquinamento fonico. Il rumore oltre a logorare i nervi, causa anche una perdita di valore degli immobili.
La limitazione della velocità di notte, dalle 22.00 alle 6.00 per Losanna è un grande passo. Le ambizioni ecologiche della capitale vodese però non si fermano qui. Entro il 2030 si prefigge di bandire il traffico motorizzato.
