Visual warning devices that include illuminated rectilinear arachnid structures that break inattentional blindness of observers. The illuminated rectilinear arachnid structures can be mounted on height-adjustable support posts that extend upright from bases. Alternatively the illuminated rectilinear arachnid structures can be provided with magnets to mount the visual warning devices to metal structures. The illuminated rectilinear arachnid structures include pairs of arms that radiate outward from a central head. The arms and central head can be made from a translucent material through which light can be transmitted to illuminate these structures. Lights for illumination can be provided in the heads. The length of the arms can be adjustable, and the arms can be retracted and/or folded into a storage configuration.

A lighted temporary barrier having a body of at least one length of hollow translucent tubing, a string of LEDs with a power source, and connectors on each end for coupling to a structure such as a traffic cone or traffic tube so as to provide a solid barrier between the two structures. The body may be made of at least a first length of translucent tubing forming a body and an optional second length of translucent tubing fitting within the first length of translucent tubing to form an extendible body. Alternatively, the body is made from a plurality of telescoping tubes, in one or both ends. The LED strand may be secured within the body or to the outside of the body.

A safety cone enhancer fits onto a traffic cone or safety cone. The traffic cone or safety cone has a conical member with a first diameter at a base of the conical member and a second diameter at a top of the conical member. The safety cone enhancer has a round or polygonal member with a hole therethrough, the hole having a diameter which is less than the first diameter of the traffic cone and greater than the second diameter of the traffic cone. The safety cone enhancer has a plurality of arms extending from the round or polygonal member; and at least one of: a first hole in said round or polygonal member extending through said polygonal member from the top surface to the bottom surface, said first hole being configured to receive a first signaling device; and a second signaling device which shines light from a surface of the round or polygonal member.

An attachment system for attachment to a signaling device includes an attachment member. The attachment member is formed of a ring-shape made of an elastic material and includes an annular base and at least one fin. The annular base includes an external peripheral edge and a central orifice defining an internal peripheral edge. The annular base also includes an annular lower face and an annular upper face. The fin projects from the external peripheral edge of the annular base. The attachment member is movable between a rest configuration in which the annular base is planar and extends in a main plane to allow insertion and positioning on the signaling device at a selected position, and a deformed configuration in which the annular base is non-planar in a deformed state in order to be able to match a peripheral area of the signaling device.

Described herein is a vehicle cone placer and chock assembly. The vehicle cone placer is equipped with collapsible traffic cones, a motorized linear actuator, and may have LED safety lights. The vehicle cone placer is telescopic, remote controlled, and mountable to a vehicle. The vehicle cone placer and chock assembly includes at least two chock systems and adjustable brackets hydraulically operated and with at least one motorized assembly. The vehicle cone placer and chock assembly is remotely operated and self-contained as components of the vehicle.

One or more techniques and/or systems are disclosed for alerting workers in a work zone of a potential intrusion by a vehicle. The example system can comprise a detection unit operable to mount to a work zone boundary marker. The detection unit can monitor the work zone for intrusion by moving objects, such as by using the Doppler Effect. The detection unit can transmit an alarm signal to one or more personnel alerters, such as worn by workers. The personnel alerters can receive the alarm signal and activate an alert, such as an audible, visual, or other sensory alert. In this way, an alert is provided to personnel working in an established work zone that a moving object, such as a vehicle, has penetrated the work zone perimeter. This type of alert may provide the personnel the vital seconds needed to move to safety.

Proposed is a smart guardrail capable of absorbing a shock induced when a vehicle collides with the guardrail to protect an occupant against the shock and of in real time performing monitoring and remote control to prevent a subsequent traffic accident. The smart guardrail, including a support fixedly installed at an equal distance at a center or an edge of a road, and a guardrail plate fixedly coupled to one or both sides of the support, further includes: a shock absorption member absorbing and thus reducing a shock induced when a vehicle collides with the guardrail; and a terminal configured to detect an external shock, an appearance of a wild animal on the road, and transmit a warning signal to an adjacent terminal positioned in a direction opposite to a traveling direction of the vehicle and to terminals positioned in succession behind the adjacent terminal.
