The low maintenance speed bump is an elongated, rigid, solid body having an arcuate top surface and a flat base, angled grooves defined in the top surface, and a reflective material disposed within the grooves. The reflective material is disposed lower than the top surface of the speed bump to prevent contact between vehicles passing over the speed bump and the reflective material. In this manner, the reflective material is protected from damage by vehicle tires and the life of the reflective material is extended. Further, the angled grooves provide greater visibility of the reflective material to drivers approaching the speed bump.

A surface marking assembly for providing guidance to vehicle operators includes first and second panels. The first panel is configured to couple to a surface, such as tarmac of a road. A plurality of solar cells is coupled to a top of the first panel. At least one battery is coupled to the first panel and is operationally coupled to the solar cells, which are configured to charge the battery. A plurality of bulbs is coupled to the first panel and is operationally coupled to the battery. The second panel, which is textured and substantially transparent, is coupled to the first panel to protect the solar cells and the bulbs. The battery is positioned to power the bulbs to provide visual direction to an operator of a vehicle proximate to the first panel. The second panel is configured to provide vibratory and auditory notifications to the operator.

A ground attachment system (1) for a tire characteristics detection unit (15) comprises an attachment plate (2) comprising a plurality of recesses (3) distributed over the surface of the attachment plate, a plurality of frustoconical clamping rings (4), and a plurality of cylindrical guide tunnels (5) arranged in the detection unit (15), the clamping rings (4) and the guide tunnels (5) each comprising a complementary conical portion (6, 7) converging towards the attachment plate (2) when the ring (4) is in the clamping position in a tunnel (5).

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.

A modular highway warning strip system which comprises a modular warning strip segment having first and second ends, a length extending between the first and second ends, two opposing lengthwise sides, a width extending between the opposing lengthwise sides of the segment, top and bottom surfaces, and a thickness. Each of the first and second ends comprise at least one male protrusion and at least one female receptacle, wherein the at least one male protrusion is configured to engage the at least one female receptacle for joining a plurality of the segments together end-to-end. Advantageously, a plurality of metallic cables are molded into the molded rubber segment and extend along substantially the entire length thereof. One of the metallic cables extends into each of the male protrusions. The cables are preferably formed of corrosion-resistant steel, and preferably are joined together to form a cable mat. The mat is molded into the segment, which segment is molded of rubber.
