On their website Bathurst Regional Council said the mobile parking patrol technology used licence plate recognition to monitor restricted parking zones.

A specialised car, fitted with a camera and computer is driven by a council ranger. As it passes cars parked in the restricted zones a photo is taken of the license plate, and the exact time, location and date are recorded on the computer. Another photo is taken after the allocated time to determine if the car has gone over the limit.

However, council's traffic engineer Dennis Valentine said it was not in council's forward plans to introduce the cars to Dubbo.

"New technology involves higher performance levels but like everything that technology comes at a cost," Mr Valentine said.

"If we were to consider it we would have to look at what the cost would be, but it's not in the forward plans to look at it."

About 1000 to 1200 vehicles per hour can be checked by the patrol cars.

"If it does come to that point, staff would research that new technology and see what was available. Part of that would be looking at the performance of it in other areas," Mr Valentine said.

"You've got to know what you want to have, you've got to know if you can afford it and you've got to know if it's financially viable."

In 2014 when Bathurst Regional Council introduced the mobile patrols parking revenue grew by 50 per cent. Parking officers issued fines worth $133,147 in the seven months from March to September, up from $87,591 in the previous seven months to March.

Mr Valentine said the possibility of a merger between Dubbo and Wellington councils would also prevent the patrol cars from being introduced in the city.

"The council amalgamation debate is still going and that's all got to be resolved before anything goes forward. But, in this case, we haven't even gone down that path," he said.

If action was ever taken to introduce the patrols it would be voted on by council, Mr Valentine said.
