Prynhawn da,
Oes rhywun wedi dod ar draws cyfieithiad ar gyfer 'smart motorway'? Traffordd glyfar? Traffordd ddeallus?
Dyma'r diffiniad:
A smart motorway uses technology to actively manage the flow of traffic. The technology is controlled from a regional traffic control centre. The control centres monitor traffic carefully and can activate and change signs and speed limits.
Diolch ymlaen llaw am unrhyw gymorth.
Cofion gorau,
Meinir
