Cafodd camerâu cyflymder cyfartalog eu codi mewn pedwar lleoliad ym mis Awst, a gwnaethant ddechrau monitro traffig y mis diwethaf. Mae cyflymderau ar yr M4 yng Nghasnewydd yn cael eu monitro gan gamerâu 'cyflymder sbot' wedi'u gosod fel rhan o'r system terfyn cyflymder cyfartalog.
Average speed cameras in 4 locations were erected in August and became operational for monitoring last month. Monitoring of speeds on the M4 in Newport is being undertaken by the ‘spot speed’ cameras installed as part of the VSL system.
