Figure 2: Ezy-Guard 4 Considerations for
Vulnerable Road Users
4.0 Consideration for Vulnerable
Road Users
Vulnerable road users include motorcyclists, pedestrians,
cyclists and other road users. Ezy-Guard 4 has been
designed to provide consideration to vulnerable road
users as follows:
Rounded Post Corners.
The Z-post contains smooth, rounded post edges and
corners mitigating the risk and severity of fractures and/
or contusions.
Energy Absorbing, Ductile Z-Posts.
The Z-posts are designed to yield by bending near
ground level. This bending action absorbs impact energy
reducing the potential for post fracturing. A fractured
or split guardrail post presents a significant laceration
hazard to vulnerable road users.
The Ezy-Guard 4 design does not contain any elements that
become projectiles and there are no aggressive edges.
Shielded Posts.
The revolutionary design of Ezy-Guard 4 shields the top
of the supporting Z-posts by positioning the top of the
rail above the posts. This eliminates dangerous snag
points, reducing the potential for the barrier to dismount
motorcyclists or cyclists. This is a significant safety benefit
compared to all guardrail and cable barrier designs
currently used within Australia.
