Rydym hefyd yn cyhoeddi’r adroddiad monitro terfynol o’r ardaloedd cyntaf a roddodd 20mya ar waith, cyn ei gyflwyno’n genedlaethol. Mae’r data hwn yn dangos bod 65% o’r cerbydau a gafodd eu monitro yn teithio 24mya neu lai, o gymharu â 50% cyn cyflwyno 20mya. Gostyngodd y rhai a oedd yn teithio ar y cyflymderau uchaf hefyd 3mya ar gyfartaledd.
We are also publishing the final monitoring report from the first areas that implemented 20mph, prior to the national roll-out. This data shows that 65% of vehicles monitored were travelling 24mph or under, compared to 50% prior to introduction of 20mph. Those traveling at the highest speeds also reduced by an average of 3mph.
