SYSTEM FOR SURVEYING AND SIGNALLING THE PRESENCE OF OBSTACLES ON THE ROADWAY

摘要

A device for detecting and signalling the presence of obstacles or impediments on the roadway comprises, in combination: at least one reflective surface facing oncoming vehicles, means for detecting obstacles and/or impediments on the roadway, means for remote signalling of the presence of danger and means for visual and/or acoustic signalling of the state of danger. Said device is constituted substantially by a cat's eye or similar reflective gem, designed to be located at the edges of the roadway or carriageway and comprising: sensors for identifying the presence, position, and speed of the vehicles (or of the obstacles) on the roadway; radiofrequency transceiver devices for remote signalling of the state of danger; devices for visual and/or acoustic signalling in situ of the hazard detected; as well as batteries for electrical supply of the aforesaid sensors and devices.
