<p>The apparatus has a sensor detecting a vehicle, and an optical indicator indicating an occupied/free status of an individual parking position (4), where the optical indicator includes a bistable indicator element that comprises an electro mechanical component i.e. flip dot. The sensor has transmit aerials for transmitting the occupied/free status by radio to a parking facility control center. The sensor and the optical indicator are placed in a sturdy casing (1) that is adapted to be mounted on one of a roadway pavement and at an overhead location.</p> |
