(WSB Radio) The commute along some of Gwinnett County's busiest roads will be getting easier.

The county will be installing a system of traffic cameras at four areas with heavy traffic.  The installations will take place in January.

One road getting a camera will be Old Norcross Road.  Officials say once it is up and running, an operator at a control center will be able to see the traffic patterns and adjust the traffic lights accordingly.  If needed, the operator can change the light from red to green, to allow better traffic flow.

"Versus the days when the engineers would have to go out and view traffic on the streets, we can sit here and make real time adjustments," says Chuck Bailey, with the county transportation department.

"If we see something in the field, we can contact 911.  They can contact us and we can make signal adjustments on the fly," he says.

Transportation officials say the cameras that are currently in place have helped during a gas leak and in other emergency situations.

The new cameras are being paid for by SPLOST funds.
