Abstract (en)
[origin: EP2551410A2] The roadway (1) with an optical-kinetic speed bar for reducing speed of passing vehicles the roadway (1) comprises at least one driving lane, in which a system of grooves (2) is milled, the grooves (2) being transversal to the direction (X) of travel in the lane, wherein the distance in between them is constant, the width of the transversal grooves (2) decreases gradually in the direction (X) travel, and the milled grooves (2) are at least partly filled with flexible material (3) having a colour contrasting with the colour of the roadway (1). The method of adapting of a roadway (1) to reduce speed of passing vehicles includes the step of milling a system of transversal grooves (2) in at least one lane of the roadway (1), wherein the transversal grooves (2) are perpendicular to the direction (X) of travel in the driving lane and the distance in between them is constant and their width decreases gradually in the direction (X) of travel in the lane and it further includes a step of filling the milled grooves (2) at least partly with flexible material (3) having a colour contrasting with the colour of the roadway (1).
