Transportation Safety Research: Crashworthiness Analysis of Road Guardrail-Vehicle Using Computer Modeling and Simulation

Transportation Safety Research: Crashworthiness Analysis of Road Guardrail Using Computer Modeling and Simulation of Vehicle Impacts.

The purpose of roadside guardrail is to absorb the impact energy of a vehicle that may have lost control and stopped and redirected by the guardrail to avoid serious crash. The computer simulation result shown in the animation accurately reproduced an actual crash test results reported in the literature.

The following excerpt is from car-accidents.com: “Accident data indicates that 50 to 60% of all reported guardrail accidents result in an injury or a fatality…… However, other accident data that takes into account unreported accidents, indicates that guardrails may be safe. This study believes that unreported guardrail impacts represent nearly 90% of the total collisions with guardrails, with the other 10% being reported. When looked at this way only 6% of guardrail accidents result in injuries or death.”

Dr. Uddin’s Note: The simulation animation that I presented in this post was originally developed as a part of the Crash Modeling and Simulation Center of Excellence project conducted at the University of Mississippi.

 

About W Uddin

Dr. Waheed Uddin is a professor of civil engineering at the University of Mississippi, USA. Previously an expert for the United Nations, he is the Founder and Director of Center for Advanced Infrastructure Technology (CAIT). He has been conducting research and geospatial applications in infrastructure asset management and disaster mitigation areas for over a decade, such as Hurricane Katrina damage assessment on Mississippi Gulf Coast, tsunami simulation for a coastal city, and great floods of Indus River in Pakistan and Mississippi River in the U.S. He completed a USAID funded transportation management project for the National Academies involving satellite imagery based traffic map and video surveillance technology for Karachi. Dr. Uddin conducted airborne LIDAR survey technology projects for NASA Stennis Space Center and the National Academies/FAA. He developed many applications of remote sensing technologies and geospatial mapping, which can expedite nonintrusive landuse/infrastructure mapping and in-service monitoring.
