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. A segmented metallic plate is disposed between upper and lower rubber layers, the segmented plate comprising a plurality of segments separated by slits comprising living hinges.

What is needed is an apparatus and system for creating high contrast to heighten marking conspicuousness and heighten driver safety under extreme light conditions. According to the present disclosure, a ridged contrast surface marking may comprise a topography that may allow for consistently visible and conspicuous messaging of proximate base surface markings, which may limit loss of visibility or conspicuity during extreme light conditions. In some aspects, ridged contrast surface markings may be used in conjunction with more traditional contrasting and color techniques, such as with painting, coating, or tape. Ridged contrast surface markings may provide surrounding contrast to flat messaging or other profiled solutions, wherein even if light reflection in extreme light conditions may reduce visibility of the message, sufficient surrounding contrast would still allow for comprehension of the message.

Various examples are provided related to multi-purpose context-aware bumps (CABs) that can support dynamic adaptation of form factors and functionality. In one example, a CAB system can include sensors distributed in a traffic network and communicatively coupled to a remotely located computing environment; context-aware bumps (CABs) placed in the traffic network and communicatively coupled to the remotely located computing environment; and a CAB application configured to adjust a form factor of a CAB in response to information obtained from the sensors and/or CABs. In another example, a method can include receiving, by a remotely located computing environment, traffic information from sensors distributed in a traffic network or CABs placed in the traffic network; communicating, by the remotely located computing environment, a form factor control to a CAB in response to the traffic information; and adjusting a form factor of the CAB in response to the form factor control.

A cargo carrier for portable nimble strips that is mountable to a vehicle has a support surface that is configured to support multiple portable rumble strips. The support surface also is configured to move between a deployment position having a first width and a transit position having a second width that is less than the first width. The cargo carrier includes a frame that defines the support surface. In the illustrated embodiment, the support surface is divided along a major width dimension into at least three planar segments that are movable relative to one another to alter the overall width of the support surface, including a center portion and lateral portions extending from opposing sides of the center portion. The lateral portions are pivotably movable between extended positions aligned with the center portion in a horizontal orientation and retracted positions inclined relative to the center portion.

An automated rumble strip assembly includes a frame having a top surface configured to support a vehicle tire moving along the frame. The automated rumble strip assembly also includes a plurality of elongate members, each elongate member having a top surface. The automated rumble strip assembly also includes an actuator assembly configured to move the elongate members from a first position where each of the top surfaces of the elongate members is flush with the top surface of the frame, to a second position where each of the top surfaces of the elongate members is recessed relative to the top surface of the frame.
