Median and roadside guardrails: An essential and effective countermeasure for RwD crashes

Research and studies show how devices are important components of integrated traffic safety system

In a study conducted by the Sleep Education Research Foundation, it was revealed driving while tired is just as dangerous as driving drunk. Driving drowsy makes the motorist incapable of staying alert and many tired drivers tend to fall asleep while driving, which prohibits them from adequately responding to changes in road conditions—resulting in crashes.

This was the case for Ben Tanberg, who is an electrical engineer who works for an airline company. In July 2016, Tanberg was driving to a golf course in Montana when he started to feel drowsy and nodded off for a short period. Realizing this, Tanberg headed to get coffee but nodded off completely before he could reach the exit. He was traveling at a speed of 75 mph while his sedan swerved to the right and collided with a guardrail terminal.

The guardrail did exactly what it was designed to do: The guardrail’s end terminal absorbed the energy of the impact and deflected the guardrail away from the vehicle. This resulted in the gradual slowing of the vehicle, allowing it to come to a full stop. Tanberg was able to leave the scene of the crash uninjured.

Tanberg’s story is one of many that demonstrates guardrail save lives. For example, since the Minnesota Department of Transportation (MNDOT) first began installing the devices in 2004, cable median barriers have saved approximately 80 lives. Additionally, the Michigan Department of Transportation estimates that cable guardrails have the potential to save about 13 lives as well as prevent 51 severe injuries every year in the state.
