Europe begins testing vehicle-to-vehicle and vehicle-to-infrastructure communications systems

Under pressure to improve safety and reduce traffic congestion, fuel consumption, and carbon dioxide emissions, the European Union has spawned a batch of projects to give cars the ability to communicate wirelessly with the road and among themselves. The effort, similar to some in Japan and the United States, has reached a major milestone following a June EU ruling that set aside RF spectrum for vehicle-to-vehicle communication. Those developing car- and road-communications systems will begin testing their wares this fall ahead of large-scale road trials at six sites in Europe, which will begin in early 2009. Experts expect the technologies to begin commercial deployment as soon as 2011.

There's been no shortage of ideas. A car might share data with other vehicles over a distance of 20 to 200 meters, giving the driver enough time to intervene and avoid a crash or, if a crash is inevitable, to provide data that optimizes usage of air bags, motorized seat-belt pretensioners, and extendable bumpers. Or a vehicle could communicate directly with others and with roadside infrastructure, using a dynamic local map to help the driver quickly respond to warnings of congestion and make better decisions about his or her route. Now these and other concepts are being tested at the Lindholmen Science Park, in Göteborg, Sweden.

We Need More Than Just Electric Vehicles

To decarbonize road transport we need to complement EVs with bikes, rail, city planning, and alternative energy

EVs have finally come of age. The total cost of purchasing and driving one—the cost of ownership—has fallen nearly to parity with a typical gasoline-fueled car. Scientists and engineers have extended the range of EVs by cramming ever more energy into their batteries, and vehicle-charging networks have expanded in many countries. In the United States, for example, there are more than 49,000 public charging stations, and it is now possible to drive an EV from New York to California using public charging networks.

With all this, consumers and policymakers alike are hopeful that society will soon greatly reduce its carbon emissions by replacing today’s cars with electric vehicles. Indeed, adopting electric vehicles will go a long way in helping to improve environmental outcomes. But EVs come with important weaknesses, and so people shouldn’t count on them alone to do the job, even for the transportation sector.
