Cohda Wireless trials vehicle-to-pedestrian (V2P) technology on city streets
In collaboration with Australian mobile network operator Telstra and the South Australian Government, Cohda Wireless has conducted the first test of V2P technology over a mobile network in South Australia’s capital, Adelaide. The technology was originally developed to allow cars and motorcycles to communicate among each other and pass information about traffic and road conditions.

In contrast to original V2X technology which is based on the IEEE 802.11p wireless protocol, the system tested by Cohda Wireless utilized cellular technology to provide an early-collision warning to a driver and also alerts a pedestrian or cyclist via a smartphone application. This technology could become available in the 16 million smartphones in use in Australia and could potentially be extended to the two billion smartphones worldwide, the company said in a press release.

Cohda Wireless CEO Paul Gray said the trials highlighted the impact of Vehicle-to-everything communications on community safety. “Giving vehicles 360-degree situational awareness and sharing real-time driving information is the only way we can create safer roads for the future,” he said. “Cohda’s ongoing partnership with Telstra also demonstrates Cohda’s ability to deliver Cellular- V2X (C-V2X) solutions, an important part of the complete V2X system.”

The technology makes use of available 4G networks to allow riders, drivers and pedestrians who are further away to reliably receive necessary information.

Before a driver turns a blind corner the system will notify them of any pedestrian or cyclist crossing the adjacent street. The system was tested using other common scenarios, such as a car and a cyclist approaching a blind corner, a car reversing out of a driveway, and a car approaching a pedestrian crossing.

The trial was funded in part by the South Australian government’s AU$10 million Future Mobility Lab Fund to boost local testing, research and development of connected and autonomous vehicle technologies.

By its own account, Cohda commands about 60 per cent of the global vehicle-to-vehicle communication market. The company previously developed a “digital protective shield” system, which transmitted information such as vehicle types, speed, position and direction of travel between cars and motorcycles, at a rate of up to 10 times per second to ensure a high level of accuracy. This service could be transmitted to any device within a several hundred-metre radius.
