I would encourage anyone who receives an invite to participate in the Wales National Travel Survey to take part and contribute their views and experiences to this important research.
Byddwn yn annog unrhyw un sy'n derbyn gwahoddiad i gymryd rhan yn Arolwg Teithio Cenedlaethol Cymru i gymryd rhan a rhoi eu barn a'u profiadau i’r ymchwil pwysig hwn.
