Abstract: A module of road safety barrier for contacting and redirecting an errant vehicle includes a first beam, a second beam, and uprights that support them. The first beam has a first longitudinal part projecting laterally with respect to the uprights and also has a second longitudinal part projecting laterally with respect to the uprights, on the opposite side of the uprights with respect to the first longitudinal part. The first longitudinal part and the second longitudinal part are each joined to both of the uprights by means of permanent joints and are joined to one another by welds or brazing so as to form an internally hollow beam with longitudinal slots. In manufacturing, the whole module is galvanized.

Abstract: A central road safety barrier includes modules mutually couplable by means of a bolt which engages holes made in protrusions extending in a longitudinal direction at the ends of the modules. Walls adjacent to the protrusions improve the transfer between the modules of an impact of an errant vehicle on the barrier and improve response to an impact. The safety barrier provides an emergency openable passage. A module may include a wall solidly constrained to an upright and adjacent to the protrusions of the module on a first side of the barrier. An openable passage module has a further wall solidly constrained to a further upright and adjacent to the protrusions of the openable passage module on a second side of the barrier.

Each cavity of the supports is accessible from outside in order to enable replacement or repair of an electronic device housed internally thereof.

Abstract: Road safety barrier assembly has a barrier and an electric circuit that can be supplied with direct current. The circuit includes an outward electric cable and a return electric cable, and sensors along the barrier for detecting impact of a vehicle against respective portions of the barrier, each sensor causing upon impact detection a switching of electric current from the outward electric cable towards the return electric cable at the respective portion of the barrier. A device is arranged so as to measure a voltage value between the outward electric cable and the return electric cable upstream of the sensors. A control unit is predisposed to receive a signal indicating the voltage value measured by the voltage measuring device and is configured to calculate the distance between the voltage measuring device and the location of impact against the road safety barrier, by applying Ohm's Law.

Abstract: A road safety device has a frame firmly connected to and arranged on a road surface and an irreversibly deformable part connected to the frame for absorbing at least part of the kinetic energy of a vehicle impacting against the road safety device. An associated monitoring system includes a control unit, an image acquiring device connected to the control unit for acquiring at least one image of a vehicle registration number that is nearing the road safety device, a memory for acquiring the image, and a vibration and/or deformation sensor connectable to the frame for detecting a reversible deformation thereof. The sensor is connected to the control unit. The control unit is predisposed to identify an impact of a vehicle against the road safety device on the basis of data received from the sensor.

Abstract: A road safety barrier with a plurality of metal cables, arranged along the side of a carriageway, for re-directing a vehicle in a case of impact, has a plurality of poles, fixed to the ground, which are distanced from one another and which are arranged one following another along the side of a carriageway. The safety barrier also has a plurality of metal cables supported by the poles, so that each metal cable is parallel to and at a predefined distance from the remaining metal cables in order to re-direct a vehicle in a case of impact. Each metal cable is fixed to each pole and is wound at least once about the lateral surface of each pole.

Abstract: A deformation guiding system for a road safety device and a road safety device group, wherein the device has a frame and a deformable longitudinal body with a first end fixed to the frame and a second end. A head is fixable to the second end of the body. A guide rail is reciprocally arranged with respect to the deformable body for identifying a deforming direction thereof which is parallel to the guide rail. Coupling means fixed to the head couple the head to the guide rail for sliding motion along the guide rail. Stabilizing means fixed to the head prevent oscillations of the head about the guide rail. The coupling and stabilizing means are reciprocally arranged and conformed so that, in an impact of a vehicle against the head, the head can slide along the guide rail without oscillating about the guide rail so as to guide the deformation of the deformable body in the deforming direction.
