In recent years, the National Highway Traffic Safety Administration (NHTSA) and the automobile industry have been involved in studying side-impact issues. The studies have focused on vehicle-to-vehicle side impacts and the injuries associated with such collisions. For the past decade, the Federal Highway Administration (FHWA) has been studying the side impact issues from a roadside safety hardware perspective, focusing on side impacts into narrow objects such as trees, utility poles, sign and light supports, and guardrail terminals. FHWA/NHTSA have signed an interagency agreement with the Department of Energy to have the Lawrence Livermore National Laboratory adapt the nonlinear finite element code DYNA3D to simulate crash impacts. In addition, FHWA and NHTSA are jointly funding the National Crash Analysis Center located on the George Washington University Virginia campus. The center maintains all FHWA and NHTSA crash films and uses these films for crash analyses, including side impacts. |
