Earlier this year, the Cabinet Secretary announced a three-phase plan on 20mph, including a National Listening Programme over the summer, which encouraged people to get involved and have their say.
Yn gynharach eleni, cyhoeddodd Ysgrifennydd y Cabinet gynllun tri cham ar 20mya, gan gynnwys Rhaglen Wrando Genedlaethol dros yr haf, a oedd yn annog pobl i gymryd rhan a dweud eu dweud.
