Risk perception and driving behaviour among adolescents in two Norwegian counties before and after a traffic safety campaign

A campaign to promote safe driving behaviour has been carried out among adolescents in two Norwegian counties since 1998. It focused on traffic accident risk perception. The aims of the present paper are to present the results of the evaluation of the effect of the campaign and to examine the association between risk perception and traffic behaviour. A representative sample of adolescents aged 18–24 years old in the two Norwegian counties participating in the campaign (experimental group), as well as a control group of adolescents in two other counties not participating in the campaign were used. Data were collected before it started in October 1998 and also after the campaign (n=4376). The pre-and post-samples consisted of independent groups of respondents. The response rate was 93%. The respondents perceived the risk to be higher after the campaign than before. The respondents of the post-sample of the experimental group also reported less risk behaviour in traffic. The number of speeding accidents was also reduced. Perceived risk was not changed among adolescents in the control group. Neither were there any changes in self-report risk behaviour. The questionnaire measured cognition-based as well as emotion-based risk perception. Model tests showed that assessments of the probability of traffic accidents and concern were non-significant predictors for self-report risk behaviour. Worry and other emotional reactions related to traffic hazards significantly predicted behaviour. Sensation seeking, normlessness (i.e. a state where social norms no longer regulate behaviour), and indifference with regard to traffic safety affected emotion-based risk perception.     

Cross-cultural comparisons of traffic safety,risk perception,attitudes and behaviour

The core aim of the present study is to examine cultural differences in risk perception and attitudes towards traffic safety and risk, taking behaviour in the Norwegian and the Ghanaian public. An additional aim is to discuss the applicability of various traffic measures, suited for low and middle income countries in Africa.Sample: The results of the present study are based on two self-completion questionnaire surveys carried out in February and March 2006. The first was a representative sample of the Norwegian public above 18 years of age (N = 247). The second was a stratified sample of Ghanaian respondents (N = 299). In Ghana the data was collected in Accra and Cape Coast.The results showed that there is potential for further improvement of safety attitudes and risk behaviour among Ghanaians as well as Norwegians. There were also differences in the respondents’ evaluation of attitudes, risk perception and behaviour. Perceived risk and attitudes also significantly predicted risk behaviour and accidents/collisions. The implications of these results for traffic safety will be discussed.     

Safety climate,safety management practice and safety performance in offshore environments

Safety climate surveys were conducted on 13 offshore oil and gas installations in separate years (N=682 and 806, respectively), with nine installations common to both years. In addition, data on safety management practices were collected by questionnaire from senior management on eight installations in each year. The associations between management practices and climate scores with official accident statistics and self-reported accident involvement were tested via a series of hypotheses. Associations were found between certain safety climate scales and official accident statistics and also the proportion of respondents reporting an accident in the previous 12 months. Proficiency in some safety management practices was associated with lower official accident rates and fewer respondents reporting accidents.     

National culture and safe work behaviour of construction workers in Pakistan

It is widely accepted that unsafe behaviour is intrinsically linked to workplace accidents. A positive correlation exists between workers’ safe behaviour and safety climate on construction sites. Construction workers’ attitude towards safety is influenced by their perception of risk, management, safety rules and procedures. Pakistan, a developing country, is currently experiencing a strong growth in its construction activities. Unfortunately, the enforcement of safety regulations in Pakistan is not widespread. Indeed, some relevant regulations are both outdated and irrelevant to daily construction operations. This paper investigates local construction workers’ behaviour, perception and attitude toward safety, and attempts to link the research findings to the influence of national culture. A three-part interview-based questionnaire survey has identified that the majority of workers have a good degree of risk awareness and self-rated competence. Additionally, workers’ intentional behaviour was empirically explained by their attitudes towards their own and management’s safety responsibilities, as well as their perception of the risk they are generally exposed to in their workplace. The paper also reveals that workers operating in a more collective and higher uncertainty avoidance environment, are more likely to have safety awareness and beliefs, which can exhibit safer on-site behaviour.     

Traffic culture as symbol exchange - A cross-country comparison of Russia and Norway

The core aim of the study was to gain insight into the cross-country differences in traffic risk perception and driving behaviour and also how culture and cultural differences may influence perceived risk and risk behaviour by comparing a sample of the Russian population with a sample of the Norwegian population. A new measurement instrument aimed at measuring culture as symbol exchange was applied. Self-completion questionnaire surveys were carried out among representative samples of the Norwegian (n = 247) and the Russian (n = 299) population aged 18 years and over. The results showed that culture defined as symbol exchange was weakly associated with risk perception. It is suggested that research carried out to date on the role of culture in risk research may have focused on criterion variables which are not very relevant. However, while traffic safety culture does not seem to be important for risk perception, this study shows that it seems to be relevant for drivers’ risk behaviour and thus it is still relevant and important to focus on traffic culture in risk research despite the fact that culture does not predict perceived risk. As symbol exchange, the newly developed measure of traffic safety culture is capable of predicting drivers’ risk behaviour in traffic and is therefore a valid predictor of traffic safety.     

Differences in risk perception,priorities, worry and demand for risk mitigation in transport among Norwegians in 2004 and 2008

The present study aimed to investigate differences in risk perception, the demand for risk mitigation, priorities and worry related to transport among the Norwegian public in 2004 and 2008. Age, gender, education, driver licence and number of injuries in transport were controlled for. The comparison was carried out with questionnaire surveys among representative samples of the Norwegian public in 2004 (n = 1730) and 2008 (n = 1864). The results showed that the perceived probabilities of transport accidents decreased, whereas the perceived severity of consequences increased during this period. Both samples estimated higher probabilities of accidents by private means of transport. The demand for risk mitigation and priorities related to transport safety increased significantly in the same period. The 2008 sample also reported more worry regarding accidents by private transport. Results were discussed in relation to transport safety campaigns, safety measures and significant accidents which occurred in this period.     

Risky driving and the perception of motorcycle accident causes among chinese motorcyclists in Hong Kong

Objective: The primary purposes of this study were to explore the relationship between risk-taking acts while driving motorcycles and perceived causes of motorcycle accidents, as well as their contribution to active involvement in traffic accidents among Chinese motorcyclists in Hong Kong. Active involvement means the riders was likely at fault for the crash. Methods: A total of 774 motorcyclists were recruited, of whom 292 had been involved in active motorcycle accident in the previous 3?years. All were asked to fill in a questionnaire, which was developed to assess their risk-taking acts while driving a motorcycle and perception of motorcycle accident causes. Results: The results of the study revealed 3 dimensions of accident causes, namely, driving-related, environment-related, and belief-related causes. These motorcycle accident causes were correlated with risk-taking acts while driving a motorcycle. A multivariate logistic regression analysis showed that risk-taking acts while driving motorcycles (adjusted odds ratio [OR]: 1.036, 95% confidence interval [CI]: 1.020-1.052), perception of driving-related cause (adjusted OR: 0.941, 95% CI: 0.916-0.967), and belief-related cause (adjusted OR: 1.134, 95% CI: 1.088-1.182) were significant factors contributing to involvement in active traffic accidents by motorcycle riders after controlling for concurrent demographic variables. Conclusions: The study highlights that perceived causes of motorcycle accidents are multidimensional, including those areas related to driving, the environment, and beliefs. It substantiates previous studies that a higher degree of driving-related risk perception is related to a lower degree of risk-taking acts while driving. Further research is needed to understand why belief-related causes, sometimes called superstitions, lead riders to believe that it is beyond their ability to affect accident causation and prevention.     

Employee risk perception related to offshore oil platform movements

The results presented in this paper are based on a self-completion questionnaire survey regarding perceived risk and organizational factors conducted among 179 respondents on an offshore oil-installation in the Norwegian part of the North Sea. The aims are (1) to measure perceived risk caused by platform movements, potentially hazardous circumstances, and during the conducting of work tasks; (2) to measure employee evaluations of organizational and social factors, and (3) to analyze the associations between risk perception and the organizational and social factors. Ordinary occupational accidents caused the greatest proportion of respondents who felt unsafe. Perceived risk caused by catastrophes and disasters also created insecurity. The respondents were most satisfied with the status of contingency measures, and especially with the use of personal protective equipment and availability of personal protective equipment.     

Impact of safety attitude,safety knowledge and safety leadership on chemical industry workers’ risk perception based on Structural Equation Modelling and System Dynamics

In chemical industry, major accidents occur occasionally. Past research has demonstrated that risk perception was relevant to safety as it might affect the behavior, which could exert influence on the probability of accidents. It is important to adjust workers' risk perception to reduce accidents in chemical industry. To achieve this goal, some key influencing factors of workers’ risk perception of were identified from 3 aspects including safety attitude, safety knowledge and safety leadership. This was accomplished by gathering empirical data from 287 workers employed in 6 Chemical plants in Jiangsu, China. The model of influencing factors of risk perception for workers was established based on Structural Equation Modelling (SEM), and the path coefficients and weights were analyzed by the SEM. On that basis, the System Dynamics (SD) model of risk perception for workers was established. The study findings revealed safety attitude and safety leadership have a direct positive impact on perception of risk probability and perception of risk severity, safety knowledge has a direct positive impact on perception of risk severity, while safety knowledge has no direct positive impact on perception of risk probability. The findings of the study can provide theoretical supports and method guidance for adjusting the risk perception of workers in chemical industry.     

Associations between sleep,risk and safety climate: A study of offshore personnel on the Norwegian continental shelf

The demands and constraints of the offshore working environment can have adverse effects on health, particularly the quality of sleep. Perceived risk and safety are significant psychological stress factors which may interfere with and deteriorate the sleep quality of offshore personnel. The present study explores the relationship between risk perception, safety climate and sleep quality. Data were collected under the auspices of the Petroleum Safety Authorities in Norway using a cross-sectional design. A total of 9601 offshore workers from 52 offshore installations on the Norwegian continental shelf participated in the study. Our findings indicate that both risk perception and safety climate are significantly related to sleep quality. The results of the present study suggest that risk perception and safety climate not only are important aspects of safety performance in the offshore industry, but also have an impact on sleep quality.

Quantification of risk perception: Development and validation of the construction worker risk perception (CoWoRP) scale

Introduction: The construction sector is leading in the number of accidents and fatalities; risk perception is the key to driving these numbers. Previous construction safety studies on risk perception quantification have not considered affective risk perception of construction workers or conducted comprehensive reliability and validity testing. Thus, this study aims to fill this need by developing a psychometrically sound instrument – the Construction Worker Risk Perception (CoWoRP) Scale – to assess the risk perception of construction workers. Method: Four phases of scale development, namely, item development, factor analysis, reliability assessment, and validity assessment were conducted with the collection and testing of data from a group (n = 469) of voluntary construction workers in Hong Kong. Results: The CoWoRP Scale with 13 items was shown to have acceptable test–retest reliability, internal consistency reliability, as well as content, convergent, discriminant, and criterion-related validity. Also, the CoWoRP Scale was affirmed to have three dimensions of worker risk perception, namely risk perception – probability, risk perception – severity, risk perception – worry and unsafe. These three dimensions of worker risk perception were negatively correlated with their risk-taking behavior. Conclusions: The CoWoRP Scale is a reliable and valid instrument for measuring the risk perception of construction workers and is expected to facilitate the construction safety studies that take risk perception of construction workers into account. Practical applications: The CoWoRP Scale could serve as an aptitude test to identify the characteristics of construction workers most likely to perceive lower risk in risky work situations. In turn, this information could help safety management provide safety training programs to those workers to enhance their risk perception and thereby minimizing their risk-taking behavior, reducing unnecessary training costs, and improving the construction safety performance.     

Risk assessment in the offshore industry

This paper describes the implementation and use of risk assessment in the offshore industry in relation to safety aspects — safety to people's life and health, as well as environment and property. Although risk assessments may be based on both qualitative and quantitative methods, the main focus here will be on quantitative risk assessments (QRA). The development of offshore QRA has been lead by a mutual influence and interaction between the regulatory authorities for the UK and Norwegian sectors of the North Sea as well as the oil companies operating here. The experience from this area has been the main basis during the writing of this paper.     

A safety barrier-based accident model for offshore drilling blowouts

Blowout is one of the most serious accidents in the offshore oil and gas industry. Accident records show that most of the offshore blowouts have occurred in the drilling phase. Efficient measures to prevent, mitigate, and control offshore drilling blowouts are important for the entire offshore oil and gas industry. This article proposes a new barrier-based accident model for drilling blowouts. The model is based on the three-level well control theory, and primary and secondary well control barriers and an extra well monitoring barrier are established between the reservoir and the blowout event. The three barriers are illustrated in a graphical model that is similar to the well-known Swiss cheese model. Five additional barriers are established to mitigate and control the blowout accident, and event tree analysis is used to analyze the possible consequence chains. Based on statistical data and literature reviews, failures of each barrier are presented. These failures can be used as guidance for offshore drilling operators to become aware of the vulnerabilities of the safety barrier system, and to assess the risk related to these barriers. The Macondo accident is used as a case study to show how the new model can be used to understand the development of the events leading to the accident. The model can also be used as an aid to prevent future blowouts or to stop the escalation of events.

Applying online fleet driver assessment to help identify,target and reduce occupational road safety risks

Many studies have shown that driver attitude and behaviour are important determinants of the likelihood of collision involvement. Knowledge of the Rules of the Road and the perception of hazards are also associated with collision involvement. The aim of this paper is to review the practical application of an online fleet driver assessment program to help identify, target and reduce occupational road safety risks. A large and unique data set collected from online assessment of drivers employed in a UK telecommunications organisation is analyzed. Data was also collected on driver demographics and their driving and collision history. Analysis of the data revealed that attitude, behaviour, knowledge and hazard perception are highly correlated with self-reported collisions. The influence of these variables on collision involvement was assessed using a Poisson regression model. Both attitude and behaviour scores exhibit a statistically significant association with collision involvement, along with other variables such as mileage driven, driver age and personality. The findings lend support to the need to create a safety culture in which driver assessment and improvement is the norm, as well as reducing exposure to risk wherever possible through better ways of working and travelling.     

Driver personality characteristics related to self-reported accident involvement and mobile phone use while driving

A causal model was developed in this study to clarify the effect of mobile phone use on driving safety. Based on the model, a series of questionnaires were developed, and 194 car drivers were interviewed based on these questionnaires. Results showed that perceived risk and mobile phone usage habits varied with different individual traits. Drivers who were prone to accidents revealed a lower perception of safety risks and a higher self-reported accident rate resulting from mobile phone use than those who were not accident-prone. Aggressive drivers were found to use mobile phones more frequently while driving but had a similar accident rate to non-aggressive drivers. Frequency in mobile phone use while driving significantly increased among aggressive male drivers regardless of accident proneness. Findings from this study imply that the perceived risk of drivers might be an ignored but important factor in the relationship between mobile phone use and driving safety. Because of the difficulty in practically identifying who is accident-prone or not, this study suggests that overall prohibition in mobile phone use while driving is needed to reduce the corresponding number of traffic accidents.

Risk perception by offshore workers on UK oil and gas platforms

This paper reports the first investigation of risk perception by workers on offshore oil and gas installations on the UK Continental Shelf, following changes in offshore safety legislation in the wake of the Piper Alpha disaster in 1988. The Offshore Safety Case regulations (Health and Safety Executive, 1992, A Guide to the Offshore Installations (Safety Case) Regulations) put the onus on the operator to identify the major hazards and to reduce the risks to As Low As is Reasonably Practicable (ALARP). The regulations specifically state that Quantitative Risk Assessments (QRA) must be used when preparing the Safety Case. However, people do not use QRA when making everyday judgements about risk; they make subjective judgements known as risk perceptions, which are influenced by a number of different factors. This study was designed to complement the extensive QRA calculations that have already been carried out in the development of Safety Cases. The aim was to measure subjective risk perception in offshore personnel and examine how this relates to the more objective risk data available, namely accident records and QRA calculations. This paper describes the Offshore Risk Perception Questionnaire developed to collect the data and reports on UK offshore workers' perceptions of the risks associated with major and minor hazards, work tasks and other activities aboard production platforms.
