A Guide on the Factors that are Connected with Road Accidents

What is a Road Traffic Accident? (RTA)

A road traffic accident is an event during which a vehicle either heads off from the road and will either end up in a ditch, or a collision with anything that can cause damage to the vehicle, including other vehicle's, telephone poles, buildings, and trees, humans or animals. Road traffic accidents (RTAs) can also be referred to as car accidents, traffic collisions, auto accidents, road accidents, personal injury collisions, motor vehicle accidents, and crashes. An estimated 1.2 million people worldwide each year are killed in some form of an RTA, and those that are injured is approximately forty times this number

Causes of Road Traffic Accidents

Environmental Factors

Rain

Rain can effect a driver's perception and produces visibility changes through its contact on headlamps, windshields, the road itself and road markings.

The rain can also affect the driver's vision visibility through the windshield. The windshield wipers are never 100% effective, the splashing of the rain and the windshield wipers block vision and objects on the road. Wipers can also leave a smear on the windscreen and only clear 2/3 of the windshield from rain. When rain is combined with dirty water or slush thrown up from the road by other drivers, windshields can quickly become dirty.

Water reduces the reflectivity of most materials. Less light falling on the object is reflected back, so the objects appear darker and have lower contrast. Pedestrians in dark clothes would become even darker and could be more difficult to see.

Sun

The sun can be a very dangerous factor for drivers as it can produce a glare by reflecting off the road and into the driver's direct field of vision, making the driver temporally blind. The sun can reflect off the drivers or other vehicles windscreen and other reflective surfaces can decrease the driver's ability to view traffic lights, signs and other road traffic.

Fog

Fog is a thin layer of cloud that can appear suddenly at any time of the day, year and in any part of the country and it can pose as the most dangerous factor on the roads. Visibility is seriously reduced by fog which increases the risk of a crash, particularly in winter season as it is a regular occurrence and death toll on the roads generally increases during this time. When the weather is foggy, the safest thing to do is to not to drive. Unfortunately many drivers come across fog during their travels; in this case the safest things for them to do are tomove off the road to the hard shoulder and wait for it to lift. Stopping on the road increases the chances of being hit because others have no way of seeing, or avoiding, until it is too late.

Ice

Black ice is ice which forms on a roadway, usually due to snow melting and re-freezing. Since it is almost invisible, drivers fail to recognize black ice conditions and may drive at normal speeds-often resulting in very serious accidents. The possibility of black ice increases when temperatures are near or below freezing and can normally be spotted on pavements that looks dry but appears darker in colour and dull-looking.

During slippery conditions stopping distances can triple and failing to have enough time to stop is a major cause of winter driving accidents as many people tend to keep the normal distance between their car and the one in front of them, generally speaking as the stopping distances triples then the general safety distance between each car should also triple. Strong or sudden cross-winds can make it difficult for drivers to stay in their lane. Following a snowfall, sometimes snow will be blown across a roadway, obscuring the road surface including possible patches of ice

Driving in the Dark

Millions of British drivers admit that they find driving more difficult in the dark as it is harder to see clearly when driving after dark and it's a fact that more road accidents occur at night than during the day. Common night driving problems include blurred vision, difficulty focusing and prevention from seeing.

Human Errors

It has been shown that human error is the sole cause of 57% in road accidents and as 90% in a contributing factor.

Being Tired

Driver fatigue may be a factor in up to 30% of fatal crashes and up to 15% of serious injury crashes. Being tired while driving does not just concern anyone driving a long distance, it can affect shift-workers, parents/carers of young children who haven't had much sleep and also those with sleep problems. It is as much a problem for city as country. Being tired can effect how a driver can control their vehicle correctly and decrease their ability to estimated and judge potential traffic hazards.

* An estimated 300 people a year are killed where a driver has fallen asleep at the wheel.

* The greatest risk of falling asleep at the wheel is between midnight to 6am and 2-4pm.

* Alcohol, drugs and medication can make you more tired without the driver's knowledge.

Ways of avoiding falling asleep at the wheel include:

* To plan a 15 minute break every two hours within every car journey.

* To have a good nights sleep before setting off on a long journey.

* Share driving responsibilities is possible.

* To pull over in a safe place if starting to fell tired.

* Opening the windows or putting on the radio doesn't help prevent falling asleep at the wheel.

Drink Driving

Alcohol can seriously impair a driver's judgment, coordination and reactions. It can be a hazard to the driver, the passengers, other road users and pedestrians, which is why drink driving is such a serious offence. Alcohol weakens a driver's ability to drive efficiently, many increase their speed while turning corners, over taking and the driving becomes more exaggerated.

Every week in the UK, 10 people will die as a result of drink-driving. Young men in their 20s are four times more likely to be involved in drink-drive accidents than other age groups. On average, 3,000 people are killed or seriously injured each year as a result of drink-driving. Drinking and driving occurs particularly among young men aged 17-29 in terms of being a casualty and testing positive for alcohol. In 2004, in the 17-24 age groups, 6% of drivers failed a breath test, compared to an average of 4.4% for all ages.

The limits

Alcohol in the body can be measured in the breath, blood or urine. A driver will be found guilty of drink-driving if he or she has more than:

* 35 microgramme's of alcohol in 100 millilitres of breath;

* 80 milligrammes of alcohol in 100 millilitres of blood;

* 107 milligrammes of alcohol in 100 millilitres of urine.

Drivers found to exceed the limits detailed above are automatically given a minimum one-year disqualification and could also be liable to paying a fine of up to £5,000 and/or up to six months imprisonment.

Age of Driver

Young drivers are far more likely to be involved in serious road accidents than other motorists: 17-20 year old male drivers are almost ten times more likely to be killed or seriously injured than more experienced drivers and, on average, one young person aged 16-19 dies each day on UK roads traveling as either a driver or a passenger. A young person's accidents is normally due to them having a lack of vehicle-handling skills, their lack of driving experience; many young drivers have a poor appreciation of road conditions and the driving behaviour of ...
