brief introduction
Temporary road signs are generally conical or cylindrical, and are generally used to remind passers-by during construction and accidents to ensure the personal safety of engineers and road users, or to separate or merge traffic diversions, people and vehicles. But in other cases, daily traffic diversion/confluence will use "permanent" road signs/signs with low portability.
The earliest traffic cone can be traced back to the concrete traffic cone made by Charles P. Rudebaker in 19 14. Since modern times, traffic cones have been made of thermoplastic or rubber, with bright warning colors to facilitate road users to observe at a distance, and recycled PVC can also be used to manufacture traffic cones. In addition to traffic cones, safety island lights can also provide similar functions.
