騎自行車是一種健身的好方法。然而這個運動在美國成年人中的普及，導致了傷亡和需要入院治療的事故急劇增加。
從美國醫院急診科的資料統計，因自行車受傷的十八歲以上的美國成人入院就診的人數在近幾年明顯增加。其中重傷者不少。和十年前相比，自行車受傷者的入院人數增加了120％，頭部受傷也從10％增加到16％。另外，45歲以上的傷者增加了81％。
研究發現，如今在美國城市馬路上騎車的人越來越多，騎車受傷的危險性也越來越大。有許多人騎喜歡運動競技型的自行車，騎車的速度越來越快。在有關部門改善馬路騎車基礎設施之前，中老年騎車者一定要考慮騎車的安全性。
Around 80% of cycling accidents occur in daylight - which is when most cycling takes place. For child cyclists, 90% of their accidents occur during the day. The most dangerous hours for cyclists are 3.00 to 6.00 p.m. and 8.00 to 9.00 a.m. on weekdays. However, cycling accidents in the dark are more likely to be fatal.
More cycle accidents occur during the Spring and Summer months (May to September) than the Autumn and Winter months (October to April). However, the casualty rate in terms of miles travelled is higher over the Autumn and Winter period.
Cycling Accidents
Around 75% of fatal or serious cyclist accidents occur in urban areas
Around half of cyclist fatalities occur on rural roads
75% happen at, or near, a road junction
80% occur in daylight
80% of cyclist casualties are male
Almost one quarter of the cyclists killed or injured are children
Around three quarters of cyclists killed have major head injuries.
Types of Accident
Human error is the main contributory factor involving cyclist collisions. Driver/rider error was the most frequently reported reason for the incident involving 73% of all reported accidents in 2014.
Accidents involving child cyclists are often the result of the child playing, doing tricks, riding too fast or losing control. For teenage and adult cyclists, accidents are more likely to involve collisions with motor vehicles, but about 16% of fatal or serious cyclist accidents reported to the police do not involve a collision with another vehicle, but are caused by the rider losing control of their bicycle.
In collisions involving a bicycle and another vehicle, the most common key contributory factor recorded by the police is ‘failed to look properly’ by either the driver or rider, especially at junctions. ‘Failed to look properly’ was attributed to the car driver in 57% of serious collisions and to the cyclist in 43% of serious collisions at junctions.
Other common contributory factors attributed to drivers are ‘poor turn/manoeuvre’ (in 17% of serious accidents involving a cyclist) and ‘careless, reckless, in a hurry (17%). Cyclists are more likely to suffer serious injuries when a driver is judged to be ‘impaired by alcohol’, exceeding the speed limit’ or ‘travelling too fast for the conditions’.
The second most common contributory factor attributed to cyclists was ‘cyclist entering the road from the pavement’ (including when a cyclist crosses the road at a pedestrian crossing), which was recorded in about 20% serious collisions (and over one third of serious collisions involving child cyclists).
The most common vehicle involved in collisions with cyclists is a car or taxi, with the rider usually being hit by the front of the vehicle. In a quarter of fatal cyclist accidents, the front of the vehicle hit the rear of the bicycle.
However, heavy goods vehicles (HGVs) present a particular danger for cyclists, especially in big city where around 20% of cyclist fatalities occur involve an HGV. These often occur when an HGV is turning left at a junction. About one quarter of accidents resulting in serious injury to a cyclist involved an HGV, bus or coach passing too close' to the rider.
Common Cycling Accidents
Motorist emerging into path of cyclist
Motorist turning across path of cyclist
Cyclist riding into the path of a motor vehicle, often riding off a pavement
Cyclist and motorist going straight ahead
Cyclist turning right from a major road and from a minor road
Child cyclist playing or riding too fast
Injury Patterns
Limb Injuries
Limb injuries are common in cyclist casualties, with over 40% suffering arm injuries and around 25% suffering leg injuries.
Chest/Abdomen Injuries
Chest and abdomen injuries occur much less frequently (5%), but are often serious. When they do occur they are often accompanied by head injuries.
Head Injuries
Head injuries, ranging from fatal skull fractures and brain damage to minor concussion and cuts, are very common injuries to cyclists. Hospital data shows that over 40% of cyclists, and 45% of child cyclists, suffer head injuries. A study of 116 fatal cyclist accidents cities and rural areas found over 70% of the cyclist fatalities in cities had moderate or serious head injuries, and over 80% of those killed in collisions on rural roads.
