The invention relates to a device for limiting the speed of moving traffic. The device comprises at least one protruding element positioned on the surface of a road that is open to traffic. The protruding element wherein the shape and dimensions thereof are such that it affects only vehicles of certain sizes, the speed of which is going to be controlled. Likewise, vehicles travelling at an acceptable speed and along an appropriate path are also not affected by the device of the invention.

1. A device for limiting the speed of moving traffic, comprising: at least one protruding element (1) positioned on the surface of a road that is open to traffic in such a way that the protruding element (1) intervenes in the path of a vehicle (3), wherein the protruding element (1) comprises a dire
1. A device for limiting the speed of moving traffic, comprising: at least one protruding element (1) positioned on the surface of a road that is open to traffic in such a way that the protruding element (1) intervenes in the path of a vehicle (3), wherein the protruding element (1) comprises a directrix line (1.1) which in a plan view has a curved shape, and the protruding element (1) is positioned in the direction of the travel of the vehicle (3) in such a way that the width (1.2) of a projection of the protruding element (1) on a transverse plane to a traffic lane is greater than the width between wheels of the same axis of a largest vehicle (3) that is anticipated to use the road and whose speed is going to be controlled,canted left and right side walls that cause the vehicle (3) to fall to the road due to the effect of gravity while following the path along the protruding element (1),lowered ends and having a different height in the center of the protruding element (1) with respect to the lowered ends, so as to dissuade drivers from passing over,where the maximum width (1.3) of the cross section is less than or equal to the width between wheels of the same axis of the smallest vehicle (3) whose speed is going to be controlled; anda hump (2) that is aligned on a same transverse axis (5) of the road as the at least one protruding element (1), with the hump (2) being located on at least one side of the lane or lanes, so that the distance (2.2) between the protruding element (1) and the hump (2) is less than the distance between the wheels of the same axis of the smallest vehicle (3) whose speed is going to be controlled, thereby allowing that vehicles with a greater width between wheels of the same axis than the width (1.2) of the projection of the protruding element (1) can go straight without being affected by the device. 2. A device for limiting the speed of moving traffic, according to claim 1, wherein the width of the cross section to the directrix line (1.1) is constant along the protruding element (1). 3. A device for limiting the speed of moving traffic, according to claim 1, wherein the width of the cross section to the directrix line (1.1) is not constant along the protruding element (1). 4. A device for limiting the speed of moving traffic, according to claim 1, wherein the corners of the protruding element (1) are rounded, cornered or bevelled. 5. A device for limiting the speed of moving traffic, according to claim 1, wherein the protruding element (1) is symmetrical about the transverse axis (5) of the road. 6. A device for limiting the speed of moving traffic, according to claim 1, wherein the protruding element (1) is asymmetrical about the transverse axis (5) of the road. 7. A device for limiting the speed of moving traffic, according to claim 1, wherein said at least one protruding element (5) comprises one protruding element (1) on each lane of the road. 8. A device for limiting the speed of moving traffic, according to claim 1, wherein the curvature of the protruding element (1) requires the vehicle (3) to move in left and right directions when following the path of the protruding element (1). 9. A device for limiting the speed of moving traffic, according to claim 1, wherein the hump (2) comprises a rectangular shape or a half ellipse shape, or a semicircle or a triangular shape, placed on a single lane road. 10. A device for limiting the speed of moving traffic, according to claim 1, wherein the hump (2) comprises a rectangular shape or an ellipse shape, or a circular shape or a triangular shape, placed between two lanes of a road with its longitudinal axis (2.1) coinciding with the line of separation of lanes (4). 11. A device for limiting the speed of moving traffic, according to claim 1, wherein the maximum width of the hump (2) will be larger than the separation of wheels of the same axis of the largest vehicle (3) whose speed is going to be controlled. 12. A device for limiting the speed of moving traffic, according to claim 1, wherein the center of the protruding element (1) has a trapezoidal cross section.
