The present invention provides a system (1000) for reducing speed of a vehicle and a method thereof which reduces the speed of the vehicle and increases fuel efficiency. The system (1000) comprises at least one protruding element (200) positioned on a surface of a roadway (110) such that the at least one protruding element (200) interrupts a smooth movement of the vehicle (100); and at least one camera (400) located away from the at least one protruding element (200) such that the at least one camera (400) is able to capture images of a monitored area of the roadway (110). The at least one camera (400) is configured to capture at least one image of a moving vehicle (100) going around and avoiding the at least one protruding element (200) in the monitored area of the roadway (110). A method for reducing speed of a vehicle is also disclosed.

Equipment for machining solid surfaces such as for example, surfaces made of asphalt or concrete or similar solid materials, in particular for making sound strips, said equipment comprising rotating machining or digging means carried by a main frame, and rotating means which engage said main supporting frame, wherein the rotation of said rotating means in a predefined direction of rotation results in said main supporting frame being rotated alternately in two opposite directions of rotation.

Methods, systems, and apparatus for a speed regulator are described. An inflatable air bag is configured to inflate to an extended configuration and configured to deflate to a retracted configuration. An air bag pump is coupled to the inflatable air bag and configured to inflate the inflatable air bag. An air bag base encases at least a portion of the inflatable air bag.

A portable roadway warning device comprises one or more rumble strips. Each rumble strip comprises at least two modular strip sections, each made of a polymeric material having top and bottom surfaces and end edges and side edges. At least one of the end edges of each of the strip sections has a plurality of aligned alternating notches and tabs, and connecting links hingedly connecting the tabs at one of the end edges of one of the strip sections to respective aligned tabs at one of the end edges of another of the strip sections. Each connecting link includes a U-shape link plate bracket and a pair of frangible rods that are configured to break at less than the tear strength of the polymeric modular strip sections.

A retractable speed bump and a method for retracting a speed bump. The retractable speed bump may include a retractile element, a chassis, and a hydraulic mechanism. The hydraulic mechanism may include a hydraulic cylinder including a hollow cylindrical shape, a hydraulic piston including a solid cylindrical shape, a first connecting rod, an oil sealing member, a return spring, a spring retainer, and a floating gasket. Responsive to downward movement of the first connecting rod at a speed higher than a threshold, the hydraulic cylinder may prevent downward movement of the first connecting rod and responsive to downward movement of the first connecting rod at a speed lower than the threshold, the hydraulic cylinder may allow downward movement of the first connecting rod.

A modular highway warning strip system is formed of a plurality of segments assembled together to create a warning strip assembly having a length, wherein each of the plurality of segments are spaced from adjacent ones of the segments along the warning strip length. The segments are assembled together along a cord disposed along the length of the warning strip assembly. A plurality of spacers are disposed on the cord along the length of the warning strip assembly, between adjacent ones of the segments in order to maintain a spacing between each adjacent segment.
