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.

    Jenoptik’s Uwe Urban looks at the advantages of ‘sensor fusion’ for the ITS sector. When considering the ideal sensing and monitoring system to enable the ITS sector to deliver improvements in mobility and road safety, for general policing security and border protection, we have to think beyond radar-base systems or laser scanners. What is needed today are solutions for detecting and tracking vehicles while recording evidence to deacide if any action is necessary. There is no sole sensor capable of

Although Floating Vehicle Data (FVD) or probe vehicle fleets have been around for about a decade, the idea behind them is of course much older: from probe vehicles that flow with the traffic it should be possible to get a precise, fast and spatially near-complete picture of the prevailing traffic flow conditions in an area under surveilla
