Eastlink trials of automated vehicle technologies ‘have delivered real results’

Trials in Australia to determine the compatibility of the latest automated vehicle technologies with EastLink have been steadily progressing throughout this year.

The trials are being undertaken by EastLink in partnership with 4728 VicRoads, the Australian Road Research Board (ARRB), La Trobe University and RACV, with the assistance of major vehicle manufacturers.

With autonomous driving on EastLink and other suitable freeways expected within the next few years (subject to legislative changes), Eastlink says the trials have produced real results for freeway operators and vehicle manufacturers to facilitate the safe and early introduction of this capability on EastLink and other Victorian freeways.

EastLink trials have already been conducted with the latest Level.2 vehicles provided by the widest range of manufacturers for a trials program of this type, including 1731 BMW, 1683 Honda, 1844 Mazda, 1685 Mercedes, 4962 Mitsubishi and 609 Volvo. The most recent technology demonstration to be completed involved a vehicle provided by 8534 Tesla. This week, a vehicle provided by 4349 Lexus has commenced trials on EastLink. In addition, 2125 Audi and 1686 Toyota will soon be providing vehicles to assist with the trials program.

Vehicle manufacturers and freeway operators are now able to work on taking advantage of these opportunities to further improve the performance of the latest Level.2 automated vehicle technologies, which will pave the way for Level.3 hands-off-the-wheel driving on EastLink and other suitable freeways, subject to legislative changes.

With Level 3 autonomous driving on the way, Eastlink envisages that freeway operators will need to communicate directly to autonomous vehicles, for example to communicate a change in conditions or operating environment (e.g. emergency incident, congestion event, or lane/tunnel/bridge/freeway closure).

As part of the trials, connected vehicle transceivers are now being installed at three of EastLink’s tolling gantries, to create a section of road enabled for vehicle to vehicle and vehicle to infrastructure communications.

Initial testing has been focused on verifying the compatibility of connected vehicle communications (5.9 GHz) with the existing DSRC tolling tag communications (5.8 GHz).

The trials program will next conduct on-road tests of different message types using suitably equipped connected vehicles.
