Road barrier energy absorbing systems and methods for making and using the same

A road barrier energy absorber system, comprising

• posts;
• road barrier energy absorption units;
• and
• a guardrail extending between the energy absorber units;
• wherein each post is disposed in one of the energy absorber units, wherein each of the energy absorber units comprise a vehicle crush section configured to absorb impact energy when impacted with greater than or equal to 5 kN force, and a guardrail attachment wherein each absorption unit comprises front and rear crushable sections disposed on opposing sides of a respective post channel configured to receive a respective road barrier post and wherein the energy absorption unit can be disposed over the post and a guardrail can be attached to the energy absorption unit.

A road barrier energy absorption unit, comprising:

• a guardrail attachment;
• a vehicle crush section couple to the guardrail attachment and defining a plurality of vehicle crush hollows, the vehicle crush section configured to absorb impact energy when impacted with greater than or equal to 5 kN force;
• and
• a rear crush section coupled to the vehicle crush section, with the energy absorption unit defining a post channel between them to receive a road barrier post;
• wherein the energy absorption unit can be disposed over the post and a guardrail can attach to the energy absorption unit.
