Bicycle safety is the use of practices designed to reduce risk associated with cycling. Some of this subject matter is hotly debated: for example, the discussions as to whether bicycle helmets or cyclepaths really deliver improved safety. The merits of bicycle lighting are less controversial.
Bicycle crashes Edit
The first recorded bicycle accident is probably a collision in 1842, reportedly between Kirkpatrick McMillan, an early rider of the velocipede, and a young girl in Glasgow. The report, however, is vague and the identification disputed.
Causes of crashes vary according to local conditions. A study conducted in 2000 by SWOV (Institute for Road Safety Research) in the Netherlands found that single bicycle accidents accounted for 47% of all bicycle accidents, collisions with obstacles and animals accounted for 12%, and collisions with other road users accounted for 40% (with the remaining 1% having unknown or unclassified cause). In most countries the dominant cause of serious cyclist injury is collisions with motor traffic.
Motorists' perceptions of cyclistsEdit
The authors of the Drivers' perceptions of cyclists research report concluded that:
... it is clear that motorists hold negative views about cyclists and tend to view cycle users as an ‘out group’ with significantly different characteristics from most road users ... the ‘out group’ status of cyclists brings with it a tendency among drivers to impute the poor or incompetent behaviour of some cyclists to all cyclists.
...the effect of infrastructure that clearly defines ownership of space, in the case of these experiments the provision of cycle lanes in the virtual reality worlds, appears to increase driver confidence and, hence, potentially risky behaviour, such as higher vehicle speeds and less speed reduction when encountering cyclists..
Defining safety Edit
Although many accidents involve a cyclist alone, collisions that also involve a motor vehicle account for a much greater number of serious injuries. A cyclist who is hit by a car is more likely to be killed than one who just falls off.
This is what one would expect; a cyclist only accident only provides a small amount of kinetic energy due to relatively small mass and low speeds, whereas a motor vehicle can provide more. Falling off and hitting obstructions tend to be relatively minor, seldom requiring medical attention, hence sparsely represented in statistics.
As long ago as the early 1930s there were efforts to clear cyclists off the roads to make way for private cars, then largely a preserve of the elite. These were successful in Germany, then an authoritarian regime, and spread during the war to German-occupied countries such as the Netherlands where civilian motor transport was also crippled by fuel rationing, but was resisted in other countries.
During the mid-part of the twentieth century, the traffic engineering response to the increased use of motor vehicles in the United Kingdom, as in the rest of the industrialised world, was to look for solutions which not only eased the passage of traffic through the streets, but which also protected vulnerable road users from the dangers of the motor car. In the 1940s, an influential proponent of this ideology was Herbert Alker Tripp, an assistant commissioner of London's Metropolitan Police. Tripp argued in his book Town Planning and Road Traffic that: "If we could segregate pedestrians completely from the wheeled traffic, we could of course abolish pedestrian casualties". This philosophy was also pursued by Colin Buchanan, his 1963 report for the UK Government Traffic in Towns, defined future government policy until the end of the century. Buchanan himself knew that segregation had not been proven to work in the case of cyclists, he famously wrote in his 1958 book Mixed Blessing "The meagre efforts made to separate cyclists from motor traffic have failed, tracks are inadequate, the problem of treating them at junctions and intersections is completely unsolved, and the attitude of the cyclists themselves to these admittedly unsatisfactory tracks has not been as helpful as it might have been".
Primary safety Edit
The state of knowledge regarding primary safety has advanced significantly through programmes such as Effective Cycling and the development of Britain's new National Standards for cycle training. In addition to technical improvements in brakes, tyres and bicycle construction generally (for example, it is now rare for a chain to snap and throw the rider when accelerating away from a stop), there are well-understood behavioural models which actively manage the risk posed by others.
Most important among these is the understanding of road position.
