Allgemeines Forum » Unfallauswertungen

Hallo Töff-Freaks,
habe heute in einem Newsletter den Hinweis auf eine grosse Studie über Motorradunfälle gefunden. Link: http://www.maids-study.eu
Die Resultate sind interessant, widerlegen teilweise auch vorhandene Vorurteile. Der Bericht hat fast 200 Seiten, darum habe ich mal Zusammenfassungen herauskopiert.
Dabei sind die PTW (powered two wheelers) die verunfallten Motorräder und die OV (other vehicles) meist Autos aller Kategorien, teilweise auch andere Motorräder.

Findings on accident causation
• The main primary contributing factors were the PTW rider (37.1%) and the OV driver (50.4%).
• In 10.6% of all cases, PTW rider inattention was present and contributed to accident causation.
• In 36.6% of all cases, the primary contributing factor was a perception failure on the part of the OV driver.
• 27.7% of PTW riders and 62.9% of OV drivers made a traffic-scan error which contributed to the accident.
• 32.2% of PTW riders and 40.6% of OV drivers engaged in faulty traffic strategies which contributed to the accident.
• A difference in speed compared to the surrounding traffic was identified as a contributing factor for PTWs in 18.0% of all cases and a contributing factor for the OV
in 4.8% of all cases.
• The weather was a contributing factor or precipitating event for the PTW in 7.4% of cases.
• 3.7% of cases involved a PTW tyre problem and 1.2% a brake problem.

Findings on human factors
• Neither males nor females were over- or under-represented in the accident population.
• Riders under 17 were neither under- nor over-represented in the accident data. Riders between 18-21 and 22-25 were over-represented, while riders between 41 and 55 were under-represented in the accident population. This suggests that riders between the ages of 41 and 55 have less risk of being in an accident when compared to the general riding population.
• 58.7 % of the L1 operators were under 21, while 88.1% of the L3 operators were over 21.
• Riders under 21 were the primary accident contributing factor 42% of the time, while riders over 21 were the primary contributing factor less then 37% of the time. Riders of all ages were most often involved in impact speeds of 50 km/h or less (70%).
• 77% of OV drivers were over the age of 26, almost all were licenced and 21% also had a PTW licence.
• OV operators who also held a PTW licence were less likely to commit perception failures than OV operators who did not have a PTW licence (26.4% versus 50.9%).
• Improperly licenced or unlicenced riders were over-represented in the accidents, suggesting that these riders have greater risk of being involved in an accident when compared to qualified riders.
• 7,8% of accidents involved riders with less than six months experience on any kind of PTW.
• In general riders with more experience are less likely to be the primary contributory factor of an accident.
• 29% of riders with less than 6 months experience had a skills deficiency and this percentage went down to 6.4% for riders with over 98 months of experience.
• Low rates of alcohol or other drug impairment were found among all riders and OV drivers. However, when the PTW rider was under influence of alcohol, he was 2.7 times more likely to be involved in an accident.

Findings on rider protection
• The most frequently reported first collision contact point for the PTW was the centre front (28.9% of all cases).
• The most frequently reported first collision contact point for the OV was the left side (21.9% of all cases).
• A total of 3644 injuries were reported. Most injuries were reported to be minor lacerations, abrasions or contusions.
• Lower extremity injuries made up 31.8% of all injuries, followed by upper extremity injuries which made up 23.9% of all injuries. Head injuries accounted for 18.7% of all reported injuries.
• Most upper and lower extremity injuries occurred as a result of impacts with the OV or the roadway.
• There were cases of helmets coming off the riders head due to improper fastening of the retention system or helmet damage during the crash sequence.
• In 69% of cases, helmets were found to be effective at preventing or reducing the severity of head injury.

Gute Fahrt!
