Researchers at the 933 Fraunhofer Institute for Communication Systems ESK in Munich, Germany, have developed a car-to-x communication (C2X) system that makes structured communication possible between an electronic unit in the vehicle and the outside world.

According to Josef Jiru, the project manager, “This system is premised upon on a WLAN specifically developed for vehicles in combination with GPS. The vehicle’s position and sensor data on speed, acceleration or sliding can be reported to wireless communication roadside units (RSUs).”

In exchange, the RSUs give vehicles three types of information – standardized messages that every car transmits to other cars and the RSUs up to ten times a second; event-based information such as notifications of accidents; and application information, for instance on traffic-light sequences that vehicles can exchange with one another, along with traffic information generally.

    A connected vehicle project in the US state of Wyoming has developed an open-source application to allow third parties to monitor safety along the I-80 highway. The Wyoming Department of Transportation (WYDoT) Connected Vehicle Pilot includes the deployment of 75 roadside units (RSUs) along 400 miles of I-80. WYDoT’s app allows authorised transportation management centre (TMC) operators to monitor and manage each RSU on the route – and can also be used to let the travelling public know what is happening.

    There is some controversy over the testing of connected and autonomous vehicles – but Robert Deans of Transurban North America explains how managed lanes could be vital in the development of CAVs, benefiting everyone. Managed lane operators have the opportunity to establish themselves as leaders in the testing and roll-out of connected and automated vehicles (CAVs), assisting and accelerating the transition of CAVs onto road networks to deliver economic and safety benefits.

However, there remain issues from manufacturer to manufacturer with interpretation of what are supposed to be common standards The 'promise' of Ethernet was that different devices such as IP video cameras and traffic signals could be easily integrated into communications networks, simplifying the process of transporting data over copper, fibre or wirelessly. However, although Ethernet devices have come to pre
