Transceiver equipment that operates in the 5.9GHz frequency range has been installed at a toll point on the tollway and tests are being carried out to check whether there is any interference with the 5.8GHz dedicated short-range communications that are used for tolling.
EastLink corporate affairs and marketing manager Doug Spencer-Roy said after this was completed, the next tests would be on a range of potential messages between a freeway and a vehicle, "for example when there is an incident ahead or lane closed information. These tests will help us develop a strategy for the future implementation of infrastructure-vehicle communications".
"We expect that vehicles with built-in 5.9Ghz transceivers will become available for sale in Australia in the next few years," he said.
Regarding the first-stage trials, Spencer-Roy said: "Among other findings, the trials demonstrated the importance of clear line markings to help vehicles 'see' the lanes of a freeway, and improve the effectiveness of some of the latest driver assistance functions such as lane keep assistance and lane departure warning."
He claimed that about 95% of accident were caused by human error and the latest driver assistance functions could help to reduce the likelihood of an accident.
Among the technologies that could help were said to be:
- Blind spot warning;
- Lane keep assistance;
- Lane departure warning;
- Dynamic cruise control; and
- Autonomous emergency braking.
The trials have been conducted along with VicRoads, the Australian Road Research Board, La Trobe University and RACV.
