Dubbo has been chosen as one of the first regional centres for the technology.

It will be rolled out on about 85 of the city's buses as part of the first phase of the Transport Connected Bus Program.

Minister for Regional Transport and Roads Paul Toole was in Dubbo on Tuesday to make the announcement.

"Dubbo is one of three regional centres statewide that is leading the charge on real-time tracking. It will allow customers to see exactly when their bus will be arriving, which means less time waiting at the stop and more time at your destination," Mr Toole said.

"The launch of this technology is a huge step forward for people travelling in regional areas. It shows our ongoing commitment to make public transport a first choice in regional parts of the state."

Ogden's Coaches Dubbo manger Peter Odgen said local operators would also benefit from the roll-out with access to more accurate data and tools to keep buses running on time.

"This technology will capture information about the number of customers getting on or off at a particular stop. This will give us a more accurate picture of how and when customers are travelling, which will make it easier for us to understand where service improvements need to be delivered," Mr Odgen said.

The rollout of the first phase of the technology is nearing completion and will launch to customers by the end of July.
