The surface of this type of vibrating coating line is distributed and scattered with raised bumps. Some bumps are coated with high-refractive-index glass beads.When a speeding vehicle runs over the raised road lines, it produces a strong warning vibration to remind the car driver of deviation from the lane.

Painted lines tended to become invisible during rain. The initial dots were made of glass [ 6 ] and were attached to the road by nails or tacks, as suggested by Botts. [ 7 ] The nails were soon abandoned: his team discovered that when the dots popped loose under stress, the nails punctured tires.
Incident light is refracted within glass beads on road surfaces and reflected into the driver's field of view. Road paint with reflective glass beads being applied to a pedestrian crossing in Baliuag, Bulacan. Glass beads composed of soda lime glass are essential for providing retroreflectivity in many kinds of road surface markings. [1]
A line drawn along the side of the road: White line: parking and stopping is allowed, but it isn't allowed on motorways and expressways. Yellow dash line: stopping is allowed, but no parking. However, some local governments allow parking at particular times. The time available for parking is written on a sign.
Animation of Kikuchi lines of four of the eight <111> zones in an fcc crystal. Planes edge-on (banded lines) intersect at fixed angles. The set of all lines through the origin in three-dimensional space forms a space called the real projective plane. This plane is difficult to visualize, because it cannot be embedded in three-dimensional space.
A rollsign on the MBTA Red Line in Boston.This sign has a hand crank to change the destinations displayed, but many rollsigns are motorized. For many decades, the most common type of multiple-option destination sign was the rollsign (or bus blind, curtain sign, destination blind, or tram scroll): a roll of flexible material with pre-printed route number/letter and destinations (or route name ...
A traffic light secured crossing has a solid line. A cycle path is represented by two points next to each other, a vehicle lane by a rectangle and tram rails by two lines lying one above the other. Islands are represented as a rectangle, which has semicircles on the right and left side.
Light exerts physical pressure on objects in its path, a phenomenon which can be deduced by Maxwell's equations, but can be more easily explained by the particle nature of light: photons strike and transfer their momentum. Light pressure is equal to the power of the light beam divided by c, the speed of light.
