Vehicle-to-infrastructure successfully tested over 4G networks

October 05, 2016 // By Christoph Hammerschmidt
The Australian telecommunications provider Telstra and telematics group Cohda Wireless have successfully tested a range of Vehicle-to-Infrastructure (V2I) applications over 4G networks. V2I, and more general, V2X is regarded as an enabling technology for intelligent connected road transport systems that will in turn open the path to better traffic management with less congestions, coordinated autonomous vehicle operation and more efficient use of the road infrastructure.

During their trials, the partners tested applications involving vehicles talking to infrastructure (such as traffic lights), vehicles communicating with other vehicles, and vehicles talking to vulnerable road users such as cyclists and pedestrians. In detail, the applications included alerting a driver to roadworks ahead, giving green light priority to high priority vehicles, and testing optimal green light timing where the vehicle is informed of the optimal speed to approach a traffic light so that that they get a green light when they arrive, therefore allowing a more continuous flow of traffic.

Telstra believes its 4G and future 5G networks can play a vital role in supporting the faster rollout of intelligent transport systems and V2X applications, making implementation of the technology cheaper and more efficient. Telstra’s Director of Technology Andrew Scott said that the successful V2I trial marked the first phase of Telstra’s plan to show how V2X technology can be supported via Telstra’s 4G network. “While there has been a lot of focus around future transport technology, there has not been much work done to date in Australia on supporting intelligent transport systems via existing 4G mobile networks,” Andrew said.

According to Andrew, this was the first phase of Telstra’s project with additional trial phases lined up for testing Vehicle-to- Vehicle and Vehicle-to-Vulnerable (bicycles and pedestrians) within the coming months.
