DRIVER DISTRACTION


DRIVER DISTRACTION



Motor vehicles disaster or car accidents are quiet happen in our country, Malaysia. These situations are happening especially during celebrating festival of the year. There are a lot of festivals celebrating in this country such as Hari Raya Puasa, Chinese New Year, Deepavali and other more. The Police of Malaysia (PDRM) had made a lot of operation to reduce the number of the accident in the entire road around the country. They introduce the operation such as Ops Sikap1, Ops Sikap2 and Ops Selamat. However there is still having the driver who does not care about the rule and made the number of accident keep increasing. The political people had debate a lot about the case in the parliament in order to find the suitable solution. However, the result still does not give many changes in the number of accident. So, in order to resolve this problem, we firstly should focus on the factors that make the accident happen. There are some factors that are highly important such as road condition, weather condition, and driver condition. All of that are come from the driver distraction. This is the topic that will elaborate more in this article.

            Driver distraction can be defined as the diversion of attention away from activities critical for safe driving toward a competing activity[1]. In the other words, there is something that takes a person who drives the car, which is their mind off other especially in more serious affairs. Psychologists have known for more than century that humans are fundamentally limited in their ability to divide attention between competing tasks[2] and that, under certain conditions (i.e., when the tasks are highly demanding, and require continuous attention[3]), the performance of one or both will inevitably suffer. There has been much debate in the scientific literature about the locus of this limitation and the psychological mechanisms that give rise to it. Diversion of attention away from activities critical for safe driving toward a competing activity can occur willingly, such as when driver initiates a mobile phone conversion, or it can occur involuntary, such as when item of information in the road environment (e.g., a moving billboard, an ambulance siren) compels the driver to attend to it. Indeed, the human mind is easily diverted from one activity to another, and there is good reason for this. From an evolutionary perspective, it is often advantageous. It is no accident of nature that certain objects, events, and activities are more diverting than others. There is biological advantage in having the human mind unwittingly orient itself toward objects, events, and activities that signify danger (such as a child running unexpectedly onto the roadway ahead, or a spider crawling on the windscreen) or to those that may be instrumental in perpetuating the species (such as other humans deemed to be attractive). Advertising material is design to exploit this gift of nature; billboards are designed to attract attention.

            As driving is a task that relies primarily on visual information, a sensible starting place is to define in general terms what sorts of visual information are present in many roadways. There are various means by which it can be determined which objects in the external environment could potentially distract a driver; one approach is presented in the following text. Other approaches would include examining the sources of distraction cited in police forms, using verbal protocol analysis while people are driving or using simulator data. The possible taxonomy of visual information in the road environment suggested here classifies entities into one of the four groups: built roadway (entities put there explicitly by road/highway engineers), situational entities, the natural environment, and the built environment[4]. One way to discover what things in the external environment are distracting is simply to ask drivers. Surprisingly, little research has been conducted in this area; however, recent research by Edquist et al.[5] explored the related issue of what drivers meant by “visual clutter” in the roadway environment. In this work, 54 drivers viewed a series of different road scenes and took part in the group discussion.


            Another one of the most frequently reported is used of a mobile, or cellular, phone. Several studies have demonstrated that the distracting effect of concurrent mobile phone use on driving performance measures is greater for older drivers compared with other age groups.  More specific areas of detection time,[6] visual scanning,[7] lane keeping and driving speed,[8] visual fixation and recognition memory, and time to dial and answer the phone. In contrast, in some studies no such age differences have been found. These authors reported that the effects of handsfree phone conversation tasks on reaction time, following distance, and speed recovery after braking did not differ between drivers aged 18-25 years and those aged 65-74. A possible reason for this finding may be that older drivers were compared with young drivers, who demonstrate similar degradations in driving when distracted. In addition, Shinar et al. demonstrated that the initial deleterious effects of handsfree phone conversations on many simulated driving tasks were reduced or eliminated with continued practise, albeit at a faster rate for younger drivers (aged 18-33) than for older drivers (aged 60-71). More specifically, in the course of five sessions, participants were given two kinds of distracting phones tasks while driving: (1) an arithmetic operations task and (2) a conversation in which participants were asked a series of questions about information they had provided before the tasks to generate conversations that would be emotionally challenging. The authors report that the effects of the distracting tasks on driving were greatest when the distracting task was difficult; the driver was older (60-71 years). All participants owned mobile phones and all reported having used their phone while driving, with reported usage rates varying from rarely to frequently.

            More recently, Greenberg et al.[9] reported that when compared with drivers aged 25-66 years, teenage drivers (16-18 years) detected fewer events occurring in a simulated roadway when dialling a handheld phone and had a higher lane violation rate when accessing voice mails. In addition, Schreiner et al.[10] also found, in a closed course study, that older drivers’ (mean age 57 years) ability to detect forward and peripheral events while concurrently driving and using a voice recognition system to dial phone numbers was impaired compared with their baseline performance. The younger to middle-aged drivers (mean age 23 years), however, did not demonstrate a performance decrement when interacting with the voice recognition system. Similarly, McPhee et al.[11] found that compared with the younger to middle-aged drivers (aged 17-33 years), older drivers (56-71 years were less accurate and slower at identifying target signs in a digitized image of a traffic scene when engaging in a simulated conversation (e.g., listening to and answering questions about a short paragraph). Finally, driving simulator research by Shinar et al.[12] demonstrated that older drivers’ (60-71) driving performance (e.g., speed control and lane keeping) was more adversely affected by phone conversations than that of middle-aged (30-33 years) and young, inexperienced (18-22 years) drivers. The driving performance of the young and middle-age groups when distracted was similar.

            Alice Chong was driving home from work and approaching a toll plaza when her phone rang. Without thinking twice, she reached for her phone which was in her handbag on the seat next to her. In the blink of an eye, her brand new car had ploughed into the back of a van. The price of that phone call? She was without a car for two months and her vehicle suffered extensive damage to the radiator, body work and engine. “I only took my eye off the road for a few seconds but that proved to be a very expensive lesson for me,” says Alice (not her real name), who swears never to touch the mobile phone again while driving. As the experts say, it only takes a second for an accident to happen. There is more concern now that more people seem to be texting while driving, a task labelled as “very distracting” for drivers. Out of the 73 billion messages Malaysians sent last year, one can only wonder how many were sent out while behind the wheel of a vehicle. This subject has come under close scrutiny of late in the United States, where many states have been introducing laws to ban texting while driving. This follows several major accidents linked to texting in the past few months.[13]

            There are no statistics available in Malaysia on the phenomenon but Malaysian Institute of Road Safety Research (Miros) director-general Prof Dr Ahmad Farhan Mohd Sadullah says that distracted driving contributes to out-of-control driving. This, in turn, is one of the biggest contributors to accidents. For collisions in 2007, out-of-control driving contributed to 23% (1,318 out of 5,672 cases) of fatal accidents and 14% of overall accidents (3,674 out of 27,035 cases). Dr Ahmad believes that mobile phones are one of the biggest distractions. “Phones are a major culprit even though we have laws prohibiting their use (while driving),” he says. He believes that road safety has a lot to do with prevailing culture and while the mobile phone has given us a sense of urgency, it has become a distraction. “When the phone rings, there is a compulsion that we have to pick it up. The mobile phone provides promptness but this is dangerous (when driving),” says Dr Ahmad. Dr Ahmad says studies have shown that using a hands-free device causes as much a distraction as talking on the phone. “When talking (without hands-free kit), we don’t have full control of the steering wheel and our concentration is divided between the conversation and the road.[14]

             A study by the Queensland University of Technology has found that self-assessment of driving skills among older drivers may produce an inaccurate appraisal of actual driving skills.  The study was primarily funded by the Trust with financial support from the Qld Department of Transport and Main Roads. The study involved a sample of 98 Brisbane drivers aged 65 years and over who had held a drivers licence for in excess of 50 years. “The results of this study indicated virtually no link between drivers’ assessment of their driving ability and their performance on the computer test,” Trust Chairman Professor Don Aitkin AO said.  “Furthermore, there was no relationship between the test results and their reported driving self-restriction. “In a nutshell, many of the drivers in the study were not as good as they thought they were,” Professor Aitkin said. This study suggests that self-assessment of driving ability may be a poor basis for decisions on the need for any driving self-restriction. “This study has provided yet more evidence that the hazard perception prowess of older drivers deteriorates with age,” Professor Aitkin said.  As a consequence, it is important for older drivers to ensure they are health-aware. “It is estimated that up to 23% of crashes and near-crashes are caused by driver distraction,” Trustee, Dr Angus McIntosh OAM said. This figure is likely to increase as more and more distractions, both inside and outside the vehicle, compete for driver attention.  “We are all familiar with the variety of things that can distract us while driving – be it using a mobile phone or adjusting the volume on the radio.  Given the contribution of driver distraction to road trauma, this unique resource is clearly compulsory reading for anyone interested in road safety,” Dr McIntosh said.
  
            In conclusion, we have much reviewed much of the knowledge that exists on driver distraction- what it means, theories describing its mechanisms, its effects. On the basis of the material reviewed, several conclusions can be drawn. There is converging evidence that driver distraction is significant road safety problem worldwide. Findings from the analysis of police-reported crashes, suggest that driver distraction is a contributing factor in 10% to 12% of crashes. Data from the 100-car naturalistic driving study in the United States, suggest that distraction from secondary tasks may be a contributing factor in up to 23% of crashes and near-crashes. Although estimates vary due to differences in definitions, data collection methods, and classification schemes, there is good reason to believe that all of these estimates underestimate the true scale of the problem. About one-third of all distractions appear to drive from outside the vehicle, and between about 15% and 20% involve driver interaction with technology. Distraction appears to be largely associated with rear-end crashes, same travel way or same direction crashes, single-vehicle crashes, and crashes occurring at night.

            Not all distraction is bad distraction[15]. The driver distraction issue has a flip side too. Some potentially distracting activities may have safety benefits, such as combating the effects of drowsiness or fatigue (as in the case of a truck driver using a CB radio[16]). There are also situations in which the attention of the individual in charge of the vehicle is drawn to circumstances other than its momentary control that may be beneficial for the personal safety and even survival of the driver, for example when taking hand off the wheel to parry the attack of a snake coiled on the passenger seat. The scientific, philosophical, legal, and moral issues concerning are important ones that remain to be explored. In order to avoid accident happen to our community, we need to aware and alert one another in the road safety. Although it might not happen to us, but it might be happen to our family. Don’t make the person that we love and we care a lot, has to be sacrificed. Loving is caring. So, in our caring, we will make love one another maybe as a friend just like Muhammad S.A.W with Abu Bakar, Umar, Othman, and Ali. The strong relationship will give the best ummah in the world. Before ending this article, I would like to remind all people to always be alert on the safety of the road and follow the regulations that had been made by our government. It is hoped that the knowledge provide in this article will help to prevent further tragedies of this kind from occurring.
