Traffic Barrier 2021

Barrier: Captures jersey barriers and walls along roads and bridges as linear features. This includes impact attenuators. Where road edges and barriers share the same delineation, the geometry is coincident.

Guardrail: Captures guardrails along roads and bridges as linear features. This includes impact attenuators. Where road edges and guardrails share the same delineation, the geometry is coincident.

Hidden Barrier: Captures hidden jersey barriers and walls along roads and bridges as linear features. Hidden barriers are features that run under other features such as bridges, overpasses, or tunnels and are not fully visible in an aerial photograph. The location is interpreted based on the information visible on either side of the visible feature. Where road edges and barriers share the same delineation, the geometry is coincident.

Hidden Guardrail: Captures hidden guardrails and walls along roads and bridges as linear features. Hidden guardrails are features that run under other features such as bridges, overpasses, or tunnels and are not fully visible in an aerial photograph. The location is interpreted based on the information visible on either side of the visible feature. Where road edges and guardrails share the same delineation, the geometry is coincident.
