Since Loss, 2010, there are 2 research study projects underway that will examine bike accidents in depth.

When these research studies are completed, we want to know that will certainly assist us to determine the nature of motorbike effects with barriers, and whether the obstacles can be redesigned without negatively impacting the excellent efficiency we have actually experienced with four-wheel traveler lorry influences to day.
