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.

The safety tripod includes a tripod, a flight driving machine mounted on the tripod to enable the tripod to fly, a landing base for seating the tripod on the ground when the tripod lands, and a standing guide mounted on the tripod to enable the tripod to stand up.

The present disclosure relates to an retroreflective structural colour film and a preparation method thereof. The main steps are as follows: (1) assembling colloidal microspheres to form a monolayer of microspheres; and (2) transferring the monolayer of microspheres onto a transparent substrate which has an adhesive layer to make the monolayer of microspheres partially embedded in the adhesive layer to prepare the retroreflective structural colour film. The retroreflective material has the advantages of the simple preparation process, high reflective brightness and uniformity of reflection colour. Moreover, the retroreflective material can exhibit unique retroreflective structural colour under the illumination of a white light source. These characteristics make the retroreflective material especially suitable for nighttime traffic safety applications, for example, to provide a constant colour signal to drivers, and simultaneously to provide dynamically changing colour signal to pedestrians to warn them of approaching vehicles.

A support for positioning a marking pole relative to a driving surface and a method of using the same is disclosed. The support includes a shaft member extending between a first end and a second end and an intermediate portion between the first end and the second end. A first anchor extends from the second end of the shaft member. A second anchor extends from an area of the shaft member between first end and the second end of the shaft member. The shaft member defines a cantilevered section between the first end and the intersection of anchor. A receiver is at the first end of the shaft and configured to receive a marking pole.

A system of retroreflectorized traffic control channelizing devices is disclosed. The system comprises a plurality of channelizing devices, each device having a reflective member that is either white, yellow, or red in color. Those having a white reflective member are used to direct traffic from a right side of a traffic lane. Those having a yellow reflective member are used to direct traffic from a left side of a traffic lane. Those having a red reflective member are used to stop traffic for a road closure. A method of use of a system of retroreflectorized traffic control channelizing devices is also disclosed.

A vehicle distance advise system includes a first housing section including a first reflective strip and a first warning device connected to the first reflective strip, and a second housing section removably connected to the first housing section. The distance advise system may be connected to a vehicle and then set-up to alert other vehicle drivers of the presence of an immobilized vehicle.
