When you are driving, you can always see the traffic
cones and lane separators in the roadside. Do you know what are the use of
them?
Nowadays, the traffic cones are usually made of PVC materials. The PVC cones have advantages of environmental protection and long life span.
The cones are are normally colored fluorescent orange and white. Those colors are used simply because they offer higher visibility. Sometimes, the white part is replaced with reflective film to improve the visibility in night. In some countries, the cones are equipped with led flashing lights in the head to improve the safety.
Lane separator is a special road safety product, which consists of rubber base, reflective film and flexible plastic flag. It is mainly placed along road sides or edges of the middle line to indicate the direction of the road and prevent the traffic hazards such as creasing etc. Since the flag with reflective film is just facing the drive direction of the vehicle, so it can be easily caught by drivers in night and rainy days.
