The Welsh Government is said to be looking at installing more speed cameras on roads with high levels of pollution.
Speed camera operator GoSafe could have its remit altered so that it can spot drivers who speed through neighbourhoods with polluted air.
According to Wales Online in June last year, the Welsh government introduced 50mph limits to cut air pollution from major roads in Wales, however most drivers failed to cut their speed down.
The 50mph were introduced last year on the M4 in Newport and near Port Talbot, the A470 in the Pontypridd area, the A483 in Wrexham and the part of the A494 in Flintshie.
Due to the poor compliance to the speed limit, the government is now talking to police and GoSafe about compelling drivers to comply. Wales Online reports that this will include deployment of average speed cameras which would operate around the clock.
Wales Online said transport minister Ken Skates told the Senedd, ‘This is to reduce the poison that is being emitted and is being inhaled by human beings. This is a measure that is proven to work. Nitrogen dioxide levels must be reduced.’
Referring to the air-quality speed limits, a government spokesman said, ‘Our officials are continuing discussions with the police and GoSafe about the most appropriate method of enforcement going forward, including average speed cameras to help ensure 24-hour-a-day compliance.’
‘It is acknowledged that existing guidance, policy and the speed awareness course curriculum may need review and amendment, and this is included within the ongoing discussions,’ added the spokesman.
