Surrogates for roadside objects, such as concrete curbs, can be used for vehicle testing. A surrogate for a concrete curb can substantially be similar in size and/or shape as the concrete curb that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart concrete curb when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test automated 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 impacted by a test vehicle without being damaged and without damaging the test vehicle.

A barrier system (100) includes first and second barrier segments (102) connected to one another such that crash energy is absorbed. The connection between the segments includes a pair of wedge-shaped connectors (202) disposed between angled faces (118) formed at the opposing ends of the segments. Elastic pads (700) are sandwiched between the respective segment faces and connectors (202).

A modular railing system for on-site assembly of a railing system along a roadway is provided. The modular railing system can include a deck with an edge beam along one side and a railing that can be attached to the edge beam. Attachment of the railing to the edge beam raises the joint between the deck and the railing to inhibit water seepage into the joint. In a specific embodiment, UHPC can be used to attach the railing to the edge beam.

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.

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.

A system for illuminating a carriageway in a case of fog includes a road safety barrier arranged along the carriageway, at least one fog density detecting device arranged along the road safety barrier, and a plurality of light sources borne by the road safety barrier, distributed along the road safety barrier, and oriented for each to emit a light beam having a direction that is transversal to an extension axis of the road safety barrier so as to illuminate signage on the carriageway. A control unit that is connected to the light sources and to the fog density detecting device is configured to activate the light sources when the fog density detecting device detects a fog density value of above a threshold value.
