Perception of own death risk: an assessment of road-traffic mortality risk

Spatial analysis of road traffic crashes and user based assessment of road safety: A case study of Rotterdam

OBJECTIVE

To perform a spatial analysis of Road Traffic Crashes (RTCs) and assess road safety issues from the perspective of road users.

PROBLEM STATEMENT

Although many initiatives have been taken to reduce the occurrence and severity of RTCs, they continue to persist. Existing research often investigates the spatial occurrence of RTCs or the perception of road safety issues from the road user. In doing this, only a limited number of factors that contribute to RTCs can be revealed, whereas in most RTC occurrences a multitude of factors plays a role. A more integrated approach combining both knowledge areas can contribute to improving road safety.

METHODS

RTCs that occurred from 2018 to 2020 in Rotterdam, in the Netherlands, were spatially analyzed. This was performed using Network Kernel Density Estimation (NKDE) analysis. Two zones within the study area were selected to understand road users' perceptions of road safety through a survey. Furthermore, opinions toward possible recommendations for improving road safety were also collected through key informant interviews.

RESULTS

NKDE resulted in a hot-spot map of the road segments in the study area that showed the frequency of RTCs using different colors. The road segments were classified based on the number of RTCs from 2018 to 2020, ranging from zero to 17.9 RTCs per kilometer. This led to the selection of a hot and cold spot zone for further analysis. The road user perception survey resulted in the discovery of qualitative responses that can be used to improve road safety in future and the possible recommendations would be well received by them. The key-informant interviews acted as a backup to the opinions given by the road users and provided insights on what is being done in the study area to improve road safety.

CONCLUSION

The synthesis of findings unveiled why road users perceive some areas as dangerous and which road policies need to be revised to improve road safety in Rotterdam.

Children's disaster knowledge, risk perceptions, and preparedness: A cross-country comparison in Nepal and Turkey

While children are one of the groups at risk in disasters, they can also take an active part in disaster management, provided that the opportunity is given. This research examined the effect of disaster experience, disaster education, country, and city socioeconomic status on children's perceived risk and preparedness with a survey of 1335 children between 11 and 14 years old, in Nepal and Turkey. The survey used questionnaires and the pictorial representation of illness and self measure (PRISM) tool. Results showed that (1) children's risk perceptions were in line with their country-specific objective risks; (2) there were differences between the countries in relation to perception of risk for all the hazards except wildfire; (3) socioeconomic status had a statistically significant effect on children's perceptions of risk and preparedness for earthquakes, wildfires, that is, children who live in wealthier places had higher perceived risk and preparedness; (4) children in both countries showed similar trends in their knowledge of the correct protective actions to take in the event of a hazard occurrence. However, there is still room to enhance children's knowledge, in terms of safety behaviors, as the children selected many incorrect protective actions. There are important implications in terms of child-centered disaster management which hopefully will make life safer and help to create more resilience to disaster in society as a whole.

Cost of two-wheeler road accidents in India

Economic loss due to traffic accidents is noticeable in India; however, the country lacks research works to estimate the magnitude. This study is an attempt through a Stated Preference (SP) survey to know how users value safety and how much they are willing to pay (WTP) for a safer road facility to reduce the risk of their involvement in road traffic accidents. The survey was conducted for two-wheeler riders of selected roads in Calicut City. Attributes selected for SP experimental design includes travel time, travel cost and traffic accidents per year and Binary Logit model was used to determine the WTP values. It was observed that travel cost, accident rate of the route selected, age, occupation, personal income and number of household members have significant impact on the decision-making process. WTP value of a road accident for a two-wheeler user was found to be Rs 0.53/person/trip.

Engaging with residents' perceived risks and benefits about technologies as a way of resolving remediation dilemmas

In recent decades the diversity of remediation technologies has increased significantly, with the breadth of technologies ranging from dig and dump to emergent technologies like phytoremediation and nanoremediation. The benefits of these technologies to the environment and human health are believed to be substantial. However, they also potentially constitute risks. Whilst there is a growing body of knowledge about the risks and benefits of these technologies from the perspective of experts, little is known about how residents perceive the risks and benefits of the application of these technologies to address contaminants in their local environment. This absence of knowledge poses a challenge to remediation practitioners and policy makers who are increasingly seeking to engage these affected local residents in choosing technology applications. Building on broader research into the perceived benefits and risks of technologies, and data from a telephone survey of 2009 residents living near 13 contaminated sites in Australia, regression analysis of closed-ended survey questions and coding of open-ended questions are combined to identify the main predictors of resident's perceived levels of risk and benefit to resident's health and to their local environment from remediation technologies. This research identifies a range of factors associated with the residents' physical context, their engagement with institutions during remediation processes, and the technologies which are associated with residents' level of perceived risk and benefit for human health and the local environment. The analysis found that bioremediation technologies were perceived as less risky and more beneficial than chemical, thermal and physical technologies. The paper also supports broader technology research that reports an inverse correlation between levels of perceived risks and benefits. In addition, the paper reveals the types of risks and benefits to human health and the local environment that residents most commonly associate with remediation technologies.

A study in a hospital setting in Trinidad and Tobago, West Indies, on the psychological factors that cause road traffic collisions

The following research paper aims to examine the psychological factors that have led to road traffic collisions (RTCs) by conducting research on drivers who had been admitted to the Accident and Emergency department at four major hospitals in Trinidad as RTC cases. A cross-sectional survey was conducted in four major hospitals in Trinidad. Sample size was 900 participants admitted to the hospital as RTC cases, and the sample was selected using Daniel's formula. All 900 participants were drivers involved in an RTC and were mostly male, and majority of drivers involved in an RTC were within the age group of 30-39 years. The survey was conducted in a 3-month window between March and June 2013. The results of the survey indicated that there was a significant relationship between most of the factors and RTCs, that is, p<0.05. This indicated that the null hypotheses did not hold. Thus, there was an positive correlation. The study revealed that attitude of drivers, real driving practice and the driving knowledge possessed by the driver were associated factors for RTCs. The survey also established that factors such as stress, the lack of sleep and fatigue were also likely to be associated with RTC.

The relative weights of direct and indirect experiences in the formation of environmental risk beliefs

Direct experiences, we find, influence environmental risk beliefs more than the indirect experiences derived from outcomes to others. This disparity could have a rational basis. Or it could be based on behavioral proclivities in accord with the well-established availability heuristic or the vested-interest heuristic, which we introduce in this article. Using original data from a large, nationally representative sample, this article examines the perception of, and responses to, morbidity risks from tap water. Direct experiences have a stronger and more consistent effect on different measures of risk belief. Direct experiences also boost the precautionary response of drinking bottled water and drinking filtered water, while indirect experiences do not. These results are consistent with the hypothesized neglect of indirect experiences in other risk contexts, such as climate change.

Risk perception, experience, and objective risk: a cross-national study with European emergency survivors

Understanding public risk perceptions and their underlying processes is important in order to learn more about the way people interpret and respond to hazardous emergency events. Direct experience with an involuntary hazard has been found to heighten the perceived risk of experiencing the same hazard and its consequences in the future, but it remains unclear if cross-over effects are possible (i.e., experience with one hazard influencing perceived risk for other hazards also). Furthermore, the impact of objective risk and country of residence on perceived risk is not well understood. As part of the BeSeCu (Behavior, Security, and Culture) Project, a sample of 1,045 survivors of emergencies from seven European countries (i.e., Germany, the Czech Republic, Poland, Sweden, Spain, Turkey, and Italy) was drawn. Results revealed heightened perceived risk for emergency events (i.e., domestic and public fires, earthquakes, floods, and terrorist attacks) when the event had been experienced previously plus some evidence of cross-over effects, although these effects were not so strong. The largest country differences in perceived risk were observed for earthquakes, but this effect was significantly reduced by taking into account the objective earthquake risk. For fires, floods, terrorist attacks, and traffic accidents, only small country differences in perceived risk were found. Further studies including a larger number of countries are welcomed.

An assessment of change in risk perception and optimistic bias for hurricanes among Gulf Coast residents

This study focuses on levels of concern for hurricanes among individuals living along the Gulf Coast during the quiescent two-year period following the exceptionally destructive 2005 hurricane season. A small study of risk perception and optimistic bias was conducted immediately following Hurricanes Katrina and Rita. Two years later, a follow-up was done in which respondents were recontacted. This provided an opportunity to examine changes, and potential causal ordering, in risk perception and optimistic bias. The analysis uses 201 panel respondents who were matched across the two mail surveys. Measures included hurricane risk perception, optimistic bias for hurricane evacuation, past hurricane experience, and a small set of demographic variables (age, sex, income, and education). Paired t-tests were used to compare scores across time. Hurricane risk perception declined and optimistic bias increased. Cross-lagged correlations were used to test the potential causal ordering between risk perception and optimistic bias, with a weak effect suggesting the former affects the latter. Additional cross-lagged analysis using structural equation modeling was used to look more closely at the components of optimistic bias (risk to self vs. risk to others). A significant and stronger potentially causal effect from risk perception to optimistic bias was found. Analysis of the experience and demographic variables' effects on risk perception and optimistic bias, and their change, provided mixed results. The lessening of risk perception and increase in optimistic bias over the period of quiescence suggest that risk communicators and emergency managers should direct attention toward reversing these trends to increase disaster preparedness.

Risk assessment in mental health: introducing a traffic light system in a community mental health team

Aims:

To reports a study in which action research approach was utilised to introduce a new system of risk assessment, based on traffic lights, into a community mental health team.

Background:

Risk management is a serious concern in community mental healthcare where there is less direct, real-time supervision of clients than in other settings, and because inadequate management of risk can have fatal consequences when service users are a risk to themselves and/or others.

Design:

An action research design was undertaken, using three phases of Look, Think and Act.

Methods:

Data were collected between January and March of 2012. In the action research phases, qualitative data were collected in focus groups with the team’s multi-disciplinary mental health professionals. Data were transcribed verbatim and analysed thematically, which involved agreement of themes and interpretations by two researchers. The Look, Think and Act phases guided the development of the project; team members worked collaboratively on the traffic light system, implemented and evaluated it.

Findings:

Themes were constructed that were discussed across the focus groups. These themes were: Ease of use; Risk identification and management; Legal status; Different teams’ views of risk; Post-implementation evaluation.

Conclusion:

Action research has been used to implement change in mental health risk management. Others internationally would benefit from considering a Traffic Light System, and in using action research to implement it.
