Straßenbelag als Raserfalle

Abstract:
Heute werden Temposünder mit Radarkameras entlarvt. In Zukunft könnte der Straßenbelag selbst Daten über die Geschwindigkeit liefern, mit der Autos über den Asphalt fahren.

Möglich wird dies mit mehrwandigen Nanoröhrchen aus Kohlenstoff, wie Baoguo Han und seine Kollegen von der University of Minnesota in Duluth schreiben (Nanotechnology, Bd.20, 2009). Eingerührt in herkömmlichen Beton machen sie die Straße zu einem großen und zugleich empfindlichen Drucksensor.
