The council's Slow Down in My Street project looked to deliver a strong message to local drivers after research showed one Wagga street recorded almost one in three drivers travelling more than 10km an hour above the speed limit.

Some speeds recorded were considered grossly dangerous, which Wagga council's road safety officer Emma Reynolds said needed to be addressed with speeding a factor in about 40 per cent of road deaths in NSW.

"During the past six months, the council has collected data across the city which not only records traffic numbers, but also the speed at which vehicles are travelling," she said.

"On several local roads, almost 13 per cent of vehicles were detected travelling up to 25km/h over the speed limit during the five-week recording period."

The five roads targeted as part of this campaign consisted of Hampden Avenue towards Cartwrights Hill, Gregadoo Road, Henwood Avenue, Copland Street and Red Hill Road.

Wagga's Highway Patrol sergeant Steve Bloomfield said officers saw a noticeable change in driver behaviour during the campaign.

"Although speeding offences were still detected, there appeared to be a lesser number than there would usually have been," he said.

"I believe that the campaign was a valuable initiative that acted as both a deterrent to offenders and a reassurance to Wagga residents."

Moving forward, community members have been asked to nominate their street before September 28 as part of another speed-focused project.

In consultation with police, the council will select five residential roads and five rural roads to become the focus of the next phase to promote safer speeds on the city's streets.
