Ideas to reduce traumatic brain injury (TBI) in bicycle and motorcycle accidents.
Helmet technology has been a crucial tool for reducing serious head injuries in general for both cyclists and motorcyclists, however many people still continue to suffer severe injuries due to movement of the brain within the skull.
Newer technologies like MIPS are great, however few motorcycle helmets implement it, and it is a patented technology that must be implemented at manufacture. Hövding is good, but is mutually exclusive to wearing a traditional helmet — it would not be permitted here in Australia for example.
Australian Standards AS/NZS 2063:2008 (Bicycle Helmets) and AS/NZS 1698 (Vehicle user Helmets) cover testing that focusses on skull protection, but both appear to overlook what goes on inside the skull.
The immediate goals of this project are threefold:
- Try to get updated statistics of the incidence of TBI in cycling and motorcycling accidents in the public domain.
- Develop a model for the skull and brain that can be used to test various impact scenarios and assess effectiveness of designs in simulation.
- Devise a system that could be retrofitted to existing helmets or embedded in new designs that is patent-free.
Long-term goals may include getting testing standards updated to account for brain injury, perhaps using whatever models we can come up with.
