The Com2React team says their technology could be useful to drivers, traffic police, emergency services and companies with a fleet of vehicles to manage.
The researchers developed a system to help inform drivers of poor weather or road conditions immediately ahead, allowing them to choose alternate routes, easing congestion and cutting down on accidents, says Dr Chanan Gabay, Com2React’s (C2R) project coordinator.
Being able to share such data is a crucial component of any future automated road traffic management system that aims to provide drivers with ‘live’ information en route. Vehicle-to-vehicle (V2V) communication is also key to the vision of the intelligent car, one able to process data and aid drivers.
The EU-funded Com2React project’s main achievement was to develop software that creates a virtual traffic control sub-centre, which temporarily forms to manage a moving group of vehicles in close proximity.
The software assigns the role of the virtual control centre automatically to one of the vehicles in the group according to rules embedded in the C2R software.
“A lot of areas are not covered by regional traffic control centres,” says Gabay. “By creating virtual sub-centres, the system extends the traffic networks to those areas.”
The sub-centre obtains and processes data acquired by the group of vehicles and rapidly provides the driver with instructions related to local traffic and safety situations.
The software also transmits selective data to a regional control centre and receives current traffic information to distribute to the vehicles. The updated ‘common knowledge’ is then processed by each vehicle’s software, allowing drivers to make informed decisions.
Local information processed locally
The concept works as information processed through the virtual sub-centre can be better directed to the relevant vehicles, avoiding information overload, says Gabay.
“Local communication is much faster than remote communication and can, therefore, enable an immediate reaction to sudden events,” he adds.
The challenge for the C2R research team was to develop software able to handle a large amount of relevant shared information intelligently. The resulting system is made up of software linked through a series of sensors.
The software is designed to handle safety alerts, link into a vehicle’s navigation system by providing real-time traffic information, and organise the data according to an individual driver’s needs.
And a prototype system, tested in Munich and Paris last summer, proves that it works. “We showed that the conceptual part of vehicle-to-vehicle communications can be done.”
Now, the team is looking for further funding to bring down the cost of the system to about €100 a vehicle before it can be accepted by vehicle manufacturers and commercialised. Currently, the system costs “thousands” of euros, he says.
The regulation and harmonisation of V2V communications could also pose another obstacle to the technology, he believes.
The Com2React team is holding seminars with ministers of transport from Israel and with the European Commission in a bid to develop the concept further.
The team is made up of researchers from Motorola, Arttic, Transver, the Technical University of Munich, INRIA, Armines-Ecole des Mines, Everis, Intempora, Telefonica, Sphericon, PSA (Peugeot Citroen), Navteq and the Jerusalem Transportation authorities.
Peugeot is interested in the technology, according to Gabay, but is waiting until the costs are brought down first. Israel’s government is also considering the technology, says Gabay. Another team member is promoting the technology in Spain.'
Their business plan forecasts that the concept and technology could be profitable after three years.
“It is a real breakthrough,” says Gabay. “As far as is known, no distributed programmes are underway in a peer-to-peer mode on top of an ad hoc network implementing a concrete traffic application.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
