Concrete barriers are one of the most widely used safety features for preventing errant
vehicles from entering opposing travel lanes on highways. As a safety device, a concrete …

The purpose of using roadside safety equipment is to protect vehicle occupants during an
accident by reducing the severity of impact. Using poorly designed safety equipment can …

Bridge rail-to-guardrail transitions are designed to shield unprotected ends of bridge rails,
which are fixed-obstacle hazards. These structures should provide an effective transition …

In terms of highway traffic safety, the W-beam guardrail plays an essential role in absorbing
impact energy, reducing occupant acceleration peaks, and redirecting the vehicle in the …

The use of nonlinear, large-deformation, dynamic finite element analysis (FEA) has become
a cornerstone in crash test simulations, playing a pivotal role in evaluating the safety …

With an average of six billion miles traveled per day on US highways, according to the
Federal Highway Administration (FHWA), transportation safety is of the utmost importance …

Road safety barriers are roadside structures installed on certain sections of the road to
improve highway safety by preventing a vehicle from leaving the road and colliding with …

Median barrier systems are safety features between opposite travel lanes to redirect or
prevent errant vehicles from intruding into oncoming traffic lanes. Different barriers systems …

This article presents a new concept design for magnetorheological dampers, where the
excitation circuit and magnetic field are applied from outside the magnetorheological …

Longitudinal barriers are considered as passive safety systems designed to shield hazards
located at roadsides against motor vehicle impacts. Since these barriers are manmade …
