Surrogates for roadside objects, such as metal guardrails, can be used for vehicle testing. A surrogate for a metal guardrail can have substantially the same size and/or shape as the metal guardrail that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart metal guardrail when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle system (e.g., a road departure mitigation system). The surrogates can be configured to withstand being crashed into by a test vehicle without being damaged and without damaging the test vehicle.

Molded plastic barrier segments, typically water or sand-ballasted, are engineered to be attached together, end-to-end, in a barrier array, with innovative features which result in low rotation between attached barrier segments. Such a low rotation barrier array will, upon impact by a vehicle, act as a re-directive barrier, rather than a capturing barrier, which is an important safety feature in some crash scenarios.

Disclosed is a shock absorber for buffering the barrier wall of a road. According to the present invention, a horizontal inner pipe bumper is inserted into a pedestal attached to a boundary of a barrier wall and joined to the support pillar. The buffer rail transversely connected to the protruding portion of the buffer pad on the front surface of the pedestal constitutes the buffer portion of the collision portion barrier wall, and when the buffer pad adhered to the inner pipe bumper is displaced upright, tension of the elastic rail connecting the buffer pad and the elastic rail block is generated, and the guard rail of the pillar is coupled to the barrier bridging body by a connecting member.

The invention relates to a barrier element (1) for bounding a carriageway comprising an elongated casing (2), including two opposing longitudinal side walls (3) and a, the two side walls joining, upper wall (4); and at least one casing support structure located in the elongate casing and connecting to both the side walls. The invention further relates to a support structure for use in a barrier element.

In an example, a system of road barriers includes a corner barrier segment, which includes a central member, a first member extending from the central member, and second member extending from the central member. The first member and the second member are configured to rotate about an axis of the central member relative to each other. The system also includes a first barrier segment coupled to the first member of the corner barrier segment via fasteners on both the first barrier segment and the first member. The system further includes a second barrier segment coupled to the second member of the corner barrier segment via fasteners on both the second barrier segment and the second member.

Surrogates for roadside objects, such as concrete dividers, can be used for vehicle testing. A surrogate for a concrete divider can have substantially the same size and/or shape as the concrete divider that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart concrete divider when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle system (e.g., a road departure mitigation system). The surrogates can be configured to withstand being crashed into by a test vehicle without being damaged and without damaging the test vehicle.

A barrier for a roadway (e.g., a highway, bridge, or other road), which can be used to manage vehicular traffic, such as to establish lanes, protect motorists and other people (e.g., pedestrians, constructions workers, etc.) against crashes or other impacts, and/or other purposes, and which may be configured to enhance its use and performance, such as by better protecting the motorists and others when impacted by vehicles (e.g., reducing deflection by deflecting less or substantially not deflecting; mitigating risks of catapulting or vaulting of vehicles; and/or otherwise improving protection provided by the barrier), facilitating transportation, installation and/or transfer of the barrier at the roadway, and/or enhancing other aspects of the barrier.

A road safety barrier has a plurality of panels flanking one another at respective vertical lateral edges thereof, made of a material deformable upon impact by a vehicle, and a plurality of vertical support elements supporting the panels. The vertical support elements include a first and a second vertical support member facing one another at the flanked vertical lateral edges of the panels, on opposite sides with respect to two major faces of the panels. The barrier has components for reciprocally blocking the first and the second vertical support member to the two opposite faces of the panels, and longitudinal stiffening elements coupled to the panels at respective upper longitudinal edges thereof.

An elongate barrier (3) comprises an outer shell in an elongate lower section of the barrier that defines a cavity (11) that receives and contains a pourable settable ballast material when the barrier is being manufactured. The barrier also comprises a solid block (15) of a ballast material in the cavity formed from the pourable settable ballast material.

An apparatus includes a base having a length in a first direction, a height in a second direction different from the first direction, and a depth in a third direction different from the first direction and the second direction. The base includes at least one sidewall having an outer surface, an inner surface, and an edge defining an open end of a cavity within the base. The base also includes a plurality of ribs extending from the inner surface of the at least one sidewall toward the open end of the cavity. The ribs of the plurality of ribs are separated from one another along the first direction. The base further includes at least one tube extending from the inner surface of the at least one sidewall toward the open end of the cavity. The apparatus also includes at least one plaque removably attached to the outer surface of base.
