HPRL Accident Analysis and Reconstruction

 

  • HPRL staff offers professional services of motorcycle and bicycle accident reconstruction and analysis. These services are currently provided for manufacturers, attorneys, government agencies, etc. The basis of this expert service is the experience of reconstructing many thousands of motorcycle and bicycle accidents for purposes of scientific research, as well as litigation and enforcement proceedings.

 

  • Because of the extensive experience in accident research and helmet testing, HPRL technical staff has expert knowledge of a wide variety of defects of design and manufacturing in motorcycles, bicycles, accessories and helmets. While there is effective regulation of motorcycle helmets by DOT and bicycle helmets by CPSC, there are many protection failures due to design and manufacturing defects of such "certified" helmets. Typical problems are frequent ejection of bicycle helmets due to "positional instability" and diffuse brain injury of motorcycle riders wearing "high performance" helmets qualified to racing standards. Fifty years experience in head protection research has included many problems of defective and dangerous helmet designs.

 

  • HPRL offers professional services of helmet examination and accident replication, for evaluation of accident performance. Complete scientific evaluation includes the biomechanical evaluation of accident events and protection performance. An inverse problem often encountered is the question of potential benefit of helmet use when an unprotected head is injured in an accident. HPRL has collected extensive data on the differences in injury patterns with and without helmets.

 

  • HPRL conducts special training for several government agencies as a public service, e.g., seminars for police agencies on motorcycle accident analysis, motorcycle helmet technology, bicycle helmet fitting at schools and bicycle rodeos. Continuous contact with local law enforcement agencies provides advisement in motorcycle operations and special accident investigations.

 

  • HPRL offers professional services of aviation accident analysis, especially regarding injury analysis and the effects of restraint system performance and helmet effectiveness. The services are provided to certain government agencies (NTSB, USN, USAF) as a public service.

 

  • HPRL is experienced in the safety problems of industry and is very familiar with the accident performance of various industrial safety helmets. HPRL staff has examined many industrial accidents involving head injury and can evaluate the performance of contemporary ANSI Z89 helmet, as well as the potential benefit of such helmets if not worn at the time of the head injury.
