Eindhoven University of Technology is working on a technique that could reduce congestion. In the future cars would be a form of cruise control cruise that is called by the developer of the technology cooperative adaptive control. Equipped for this purpose Jeroen Team doctorate for his research into CACC and submit to Tweakers how the technology works and what the benefits are.

Ploeg CACC works by combining with telemetry of predecessors. Radar data of the cars For example, information can be remotely connected to a vehicle of information about what the car is doing. In this way, the following vehicle can anticipate the acceleration or inhibition of its predecessor. That information vehicles that are equipped with the technology can drive much closer to each other than is now possible. During the demonstration, a distance of 0.3 second, about ten meters, held on the highway. The current legal distance at speeds of 120 kilometers per hour is 67 meters. The CACC technology allows cars so much closer to each drive, making the road capacity is effectively reproduced.

Because cars have a long lifetime and are subject to strict regulations, CACC will not be implemented in the majority of cars on the road in the short term. Despite this, new cars quite easy ‘instrumented’ are: the bulk of the necessary hardware in modern cars because all standard. Thus, the requirement for the GPS system, electronic throttle and braking and information already present, only the wifi transmitter is still missing. That wifi transmitter is 802.11p, a protocol specifically for vehicle communication has been developed and is called Wave.

Although CACC for passenger cars could represent a solution to the congestion problem in the long term the technology could already be deployed. Much shorter period for cargo Trucks are already obliged equipped with technology that CACC can use and there is also a financial motivation. By letting drive trucks closer together they can stay in each other’s slipstream and save fuel. That can add up to twenty percent, sufficient reason for fleet owners to invest in technology.
