The purpose of Gympie’s new, tiny radar dishes is revealed

IT may be paranoid to believe there are eyes everywhere – but when it comes to Gympie’s traffic lights the idea is not so far fetched.

Eagle-eyed Gympie Regional councillor Bruce Devereaux queried why some of the lights near Gympie Central Shopping Centre and at the top of upper Mary St were topped with radar dishes, sparking a storm of comments and speculation on his Facebook page over their function.

“We use a specialist Intelligent Transport System (ITS) software called STREAMS to remotely manage the operation of traffic signals,” a Transport and Main Roads spokeswoman said.
