<p>The system (1) has a sensor arrangement integrated in a roadway segment i.e. shaft lid (5) of underfloor system, and comprising a distance sensor (3) and a weight sensor (2). An evaluation unit (4) generates a binary output signal based upon sensor signals of the sensor arrangement, where switching states of the binary output signal indicate whether a sensitive object i.e. motor vehicles (8), is on the roadway segment. The weight sensor and the distance sensor are integrated in the shaft lid. The evaluation unit is integrated in the roadway segment. The distance sensor is formed as an ultrasonic sensor or an optical sensor.</p> |
