According to the official statistics 52 574 accidents w/injuries where a PTW was involved occurred in Germany in 2004. This is a share of 15% to all accidents w/injuries in Germany for 2004.
The GIDAS database (2001-2004) includes 737 accidents w/injuries where a PTW was involved. This is a share of 15% to all accidents w/injuries within the GIDAS database.
For the two-wheeler study a representative sample of 228 accidents from 737 accidents was taken because single case analyses are very time consuming.

Motorcycle Accident Analysis – benefit of ABS

40% non-relevant 60% ABS-relevant
Field of effect: Accidents in which ABS could reduce accident severity or improve the position relative to the opponent. Brake intervention is provided.Relevant Scenarios:
No maximum deceleration of the motorcycleBlocked rear wheelDownfall due to over braking the front or rear wheel
Procedure to evaluate the efficiency of motorcycle ABS:Comparison of real accident sequence with ideal full retarded and directional stabile ABS motorcycle (base of evaluation is the real existing tire trace).
In 60% of all accidents motorcycle ABS could influence the accident in a positive way!

Summary
The number of fatally injured motorcyclists has remained constant over the last 15 years whereas the number of fatally injured car occupants decreases (Germany). Existing safety technologies - both active and passive - can enhance motorcycle safety, provided market penetration is increased.
In 60% of all motorcycle accidents ABS could influence the accident in a positive way.
The evaluation results show that 26% of all powered two-wheeler accidents with injuries could be prevented by motorcycle ABS. An additional increased deceleration by an ABS was taken into account.
A strong decrease in the average collision speed was determined in 31% of all power two wheeler accidents. As a consequence, an significant reduction in the injury severity is expected.
