diamond on the road / traffic

Pavement marker often mounted between two lanes, which played the important role on the road. We found that the expose of the round convex part is mostly hemispherical and very slippery. Which often caused motorcycle riders skidding and easily to make the tire squeeze incomplete. Thus, we make hemispherical into multi-angular design, which could increase the friction between tire and surface and add the fixing part in to the multi-angular style pavement marker, so that is easier to replace it. This work will make traffic safer.
