The present invention relates to posts, carriages, methods of manufacturing the components and their assembly into a barrier. The invention also includes a Z post attachment includes an attachment tab 8.016 and end engagement flange 8.024, 8.026 adapted to engage the end of the post. The arrangement can include a delineator 8.030 which is skew in relation to the tab 8.016, so as to provide reflector faces 8.032 which face oncoming traffic.

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.
