A reflector having an information generation function, wherein information allowing a quick and clear understanding of a traffic system and the surrounding environment thereof can be generated by a combination of unit reflectors recognizable by a light detection and ranging (Lidar) or radio detecting and ranging (Radar) system, is proposed. The reflector includes a plurality of unit reflectors for representing information through code generation, wherein each of the unit reflectors represents information by reflecting light beams or radio waves therefrom or transmitting the same therethrough, whereby binary-coded information is generated using the reflector, which allows a Lidar system or a Radar system to recognize the generated information.

A socket mounted post system including a post with a hollow base portion attached to a spring mechanism. The spring mechanism includes a pillar, the pillar having a finger extending from the hollow base portion. The finger is engageable with a socket that is mountable in a floor. The spring mechanism allows the post to flex angularly relative to a vertical orientation of the post.

A collision detection system (1) for detecting and assessing the state of a crash guard (2), comprising at least one crash guard (2), which is provided with a sensor for detecting a collision onto or against the said crash guard (2), wherein the said system comprises a processing unit, which is provided to assess, on the basis of the signals generated by the sensor, the effect of a collision on the crash guard (2) and, if necessary, to initiate an alarm signal.

There is disclosed a pole support for removably supporting a hollow tubular pole, wherein the pole has a latching recess provided along its length. The pole support includes a housing defining a socket that is open at its operative upper end for receiving the pole. A latch is located within the socket and is mounted on a pivot to be pivotally movable between a latched position and an unlatched position. The latch has a latching arm extending on one side of the pivot and a ballast arm extending on an opposed side of the pivot, wherein a centre-of-weight of the latch is located off-centre from the pivot in the ballast arm so that ballast arm normally biases latch under gravity into its latched position.

A portable, self-illuminating traffic sign having a sign head with two opposite sides. One side indicates a first traffic signal, and the other side indicates a second traffic signal. Light assemblies are attached to each side of the sign head. The light assemblies emit light that may match the predominant color of one of the sides of the sign head. A battery may be disposed in a pole that connects to the sign head. A handlegrip allows for the sign to be held and provides a switch to allow for the lights to be selectively turned on and off.
