È entrato in funzione oggi, venerdì, a Winterthur il primo semaforo parlante in Svizzera. Quando il pulsante viene premuto, una voce femminile dice in tedesco: "Grazie, diventerà presto verde".
L'iniziativa per un progetto pilota di questo tipo è arrivata dalla polizia cittadina.
Indicazioni per i non vedenti
Oltre all'introduzione del controllo vocale, il dispositivo ha un altro vantaggio per le persone non vedenti: su un lato vi sono delle informazioni stradali scritte in rilievo col sistema Braille. Queste indicano ad esempio se la strada è dotata di due o tre corsie e se vi è un'isola al centro. Il congegno regola il proprio volume secondo il livello di rumore.
La fase di test servirà a verificare la funzionalità e la resistenza alle condizioni atmosferiche e ad eventuali episodi di vandalismo.
