Dilston Bypass

The Tasmania state government in Australia has revealed that it will test an intelligent transport system (ITS) designed to improve safety at the northern junction of the Dilston Bypass from this month onwards.

The Minister for Infrastructure, David O’Byrne, said the system is being installed to address community concerns about poor visibility in winter fog.

"This is another excellent example of using modern technology to make our roads and highways safer," Byrne said.

"While it’s encouraging that the number of deaths and serious injuries on our roads is trending down, every life is precious, and there’s still more work to do."

The intelligent traffic system is tasked with improving safety on the East Tamar Highway in particular, and consists of a weather station linked to variable speed limit signs.

It will use high-visibility LED signs designed for foggy conditions, to improve safety at the junction.

The system will automatically adjust the speed limit according to the weather conditions, including fog, and will also warn drivers who fail to slow to a safe speed with a ‘check your speed’ electronic sign.

Vehicles approaching the northern junction on the East Tamar Highway will see a ‘watch for turning traffic’ electronic warning sign.

The electronic signs warn the motorists waiting to enter the traffic stream to be extra cautious.

During the testing period, mobile variable message signs located on the approaches to the area will inform motorists that the new signs are being tested.

Once the testing is finished, they’ll be switched-off until the official turn-on date later this year.

The state Government has earmarked an investment of around AUS$12m a year from the Road Safety Levy for education and infrastructure.
