VW gives traffic lights a voice – pilot project in Wolfsburg

Beginning next year, VW plans to bring the first truly networked cars to the market. The technology is currently being tested and demonstrated in Wolfsburg. In the future, cars should be able to communicate not only with one another but also with the infrastructure along the roadway. How that could happen is currently being tested by Volkswagen and Siemens in Wolfsburg city traffic. A total of ten traffic lights are now being equipped with WLAN transmitters that emit information about the red and green phases to the surrounding area. Partially automated cars, equipped with a suitable receiver, will then adjust their speed so that traffic flows as smoothly as possible.


Furthermore, two intersections are being equipped with sensors for detecting pedestrians and cyclists. Approaching cars can thereby be warned of possible collisions. This should help prevent accidents and improve traffic safety.


With the project, VW hopes to demonstrate the possibilities of its vehicle networking. Beginning next year, the first cars of the brand will be equipped standard with communication interfaces based on the pWLAN wireless communication standard. The range of the data transmission is approximately 500 metres. (SP-X)
