Questioning penalties and road safety Policies: Are they enough to deter risky motorcyclist Behavior?

Reducing risky behaviors and traffic violations is crucial for preventing road trauma among private and commercial motorcyclists. While legal interventions such as road rules and police enforcement have been somewhat effective, there is a gap in understanding how motorcyclists perceive these deterrents and the psycho-social factors influencing their effectiveness. This research aims to explore the interplay between motorcyclists' psycho-social predispositions and their responses to legal interventions. It also compares two distinct groups of riders - private and commercial motorcyclists - within the urban environment of Da Nang, Vietnam, providing a nuanced consideration of the influence of work-related impacts on risky behavior, which can enable targeted interventions. We propose a theoretical model integrating the Theory of Planned Behavior and Deterrence Theory to analyze how psycho-social and punitive factors influence riders' traffic violations. A total of 423 delivery riders and 411 private riders in Da Nang participated in the study. The results show that attitude, perceived behavioral control, and perceptions of deterrence significantly impact riders' intentions to engage in risky behaviors, with delivery riders being particularly responsive to law enforcement and penalties. To enhance policy effectiveness, interventions should employ tailored enforcement strategies that account for the unique motivations and perceptions of each rider group. For example, increasing the visibility and consistency of law enforcement could be particularly impactful for delivery riders, who are more sensitive to immediate deterrents. Policy adjustments should also focus on reshaping riders' attitudes toward safety and adjusting their perceived control over riding situations. By tailoring interventions to effectively influence each group's behavior, we can ultimately reduce traffic incidents.

[Checking the fitness to drive of senior citizens under German law-pending corrective measures to ensure road safety]. / Die Überprüfung der Fahreignung von Senioren nach deutschem Recht ­ Anstehende Korrekturbedarfe zur Gewährleistung der Verkehrssicherheit.

German driving licence law takes a reactive approach to dealing with suitability deficiencies of senior citizens. If the driver is no longer fit to drive and nevertheless participates in traffic, an administrative offence has been committed. If this endangers or injures other people or causes significant damage to property, it may even be a criminal offence. In addition to prosecuting these offences, the driving licence authority may restrict or even withdraw the licence issued. In this respect, senior citizens have a high degree of personal responsibility when assessing their fitness to drive. This article presents the current driving license law and discusses the need for changes.Legally, various corrections are required to the current Driving Licence Ordinance and its annexes. At present, there is no clear regulation regarding the general reduction in performance in old age for an event-related assessment of fitness to drive. In addition, in the event of doubts about fitness to drive, the driving licence authority should be expressly granted the power to order standardised driving tests. Furthermore, the legislator must take preventive measures to ensure road safety. He must no longer ignore the current accident situation. In view of the fact that senior citizens aged 75 and over are disproportionately involved in traffic accidents with personal injury in terms of their culpable behaviour, it is important to impose moderate restrictions on the personal responsibility of driving licence holders. This is especially true for sensory abilities, which are particularly important in road traffic. Seniors should therefore be required to undergo eye tests from the age of 75. From this age onwards, it also seems sensible to introduce compulsory advice on fitness to drive, preferably from your family doctor.

Perceptions of vulnerable roadway users on autonomous vehicle regulations.

INTRODUCTION: Development and implementation of autonomous vehicle (AV) related regulations are necessary to ensure safe AV deployment and wide acceptance among all roadway users. Assessment of vulnerable roadway users' perceptions on AV regulations could inform policymakers the development of appropriate AV regulations that facilitate the safety of diverse users in a multimodal transportation system. METHOD: This research evaluated pedestrians' and bicyclists' perceptions on six AV regulations (i.e., capping AV speed limit, operating AV in manual mode in the sensitive areas, having both pilot and co-pilot while operating AVs, and three data-sharing regulations). In addition, pedestrians' and bicyclists' perceptions of testing AVs in public streets were evaluated. Statistical testing and modeling techniques were applied to accomplish the research objectives. RESULTS: Compared to the other AV regulations assessed in this research, strong support for AV-related data sharing regulations was identified. Older respondents showed higher approval of AV testing on public roadways and less support for regulating AVs. AV technology familiarity and safe road sharing perceptions with AVs resulted in lower support for AV regulations. CONCLUSIONS: Policymakers and AV technology developers could develop effective educational tools/resources to inform pedestrians and bicyclists about AV technology reliability and soften their stance, especially on AV regulations, which could delay technology development. PRACTICAL APPLICATIONS: The findings of this research could be used to develop informed AV regulations and develop policies that could improve pedestrians' and bicyclists' attitudes/perceptions on regulating AVs and promoting AV technology deployments.

Law compliance decision making for autonomous vehicles on highways.

As autonomous driving advances, autonomous vehicles will share the road with human drivers. This requires autonomous vehicles to adhere to human traffic laws under safe conditions. Simultaneously, when confronted with dangerous situations, autonomous driving should also possess the capability to deviate from traffic laws to ensure safety. However, current autonomous vehicles primarily prioritize safety and collision avoidance in their decision-making and planning. This may lead to misunderstandings and distrust from human drivers in mixed traffic flow, and even accidents. To address this, this paper proposes a decoupled hierarchical framework for compliance safety decision-making. The framework primarily consists of two layers: the decision-making layer and the motion planning layer. In the decision-making layer, a candidate behavior set is constructed based on the scenario, and a dual layer admission assessment is utilized to filter out unsafe and non-compliant behaviors from the candidate sets. Subsequently, the optimal behavior is selected as the decision behavior according to the designed evaluation metrics. The decision-making layer ensures that the vehicle can meet lane safety requirements and comply with static traffic laws. In the motion planning layer, the surrounding vehicles and the road are modeled as safety potential fields and traffic laws potential fields. Combining the optimal decision behavior, they are incorporated into the cost function of the model predictive control to achieve compliant and safe trajectory planning. The planning layer ensures that the vehicle meets trajectory safety requirements and complies with dynamic traffic laws under safe conditions. Finally, four typical scenarios are used to evaluate the effectiveness of the proposed method. The results indicate that the proposed method can ensure compliance in safe conditions while also temporarily deviating from traffic laws in emergency situations to ensure safety.

Safe and just Earth system boundaries.

The stability and resilience of the Earth system and human well-being are inseparably linked1-3, yet their interdependencies are generally under-recognized; consequently, they are often treated independently4,5. Here, we use modelling and literature assessment to quantify safe and just Earth system boundaries (ESBs) for climate, the biosphere, water and nutrient cycles, and aerosols at global and subglobal scales. We propose ESBs for maintaining the resilience and stability of the Earth system (safe ESBs) and minimizing exposure to significant harm to humans from Earth system change (a necessary but not sufficient condition for justice)4. The stricter of the safe or just boundaries sets the integrated safe and just ESB. Our findings show that justice considerations constrain the integrated ESBs more than safety considerations for climate and atmospheric aerosol loading. Seven of eight globally quantified safe and just ESBs and at least two regional safe and just ESBs in over half of global land area are already exceeded. We propose that our assessment provides a quantitative foundation for safeguarding the global commons for all people now and into the future.

An Assessment of Global Neurotrauma Prevention and Care Delivery: The Provider Perspective.

BACKGROUND: Neurotrauma is a leading cause of morbidity and mortality around the world. Assessment of injury prevention and prehospital care for neurotrauma patients is necessary to improve care systems. METHODS: A 29-question electronic survey was developed based on the Enhancing the Quality and Transparency Of health Research (EQUATOR) checklist to assess neurotrauma policies and laws related to safety precautions. The survey was distributed to members of World Health Organization regions that were considered to be experienced medical authorities in neurosurgery and traumatic brain injury. RESULTS: There were 82 (39%) responses representing 46 countries. Almost all respondents (95.2%) were within the neurosurgical field. Of respondents, 40.2% were from high-income countries (HICs), and 59.8% were from low- and middle-income countries (LMICs). Motor vehicle accidents were reported as the leading cause of neurotrauma, followed by workplace injury and assault. Of respondents, 84.1% reported having a helmet law in their country. HICs (4.38 ± 0.78) were ranked more likely than LMICs (2.88 ± 1.34; P = 0.0001) to enforce helmet laws on a scale of 1-10. Effectiveness of helmet laws was rated as 3.94 ± 0.95 out of 10. Measures regarding prehospital care varied between HICs and LMICs. Patients in HICs were more likely to use public emergency ambulance transportation (81.8% vs. 42.9%; P = 0.0004). All prehospital personnel having emergency training was also reported to be more likely in HICs than LMICs (60.6% vs. 8.7%; P = 0.0001). CONCLUSIONS: When injuries occur, timely access to neurosurgical care is critical. A focus on prehospital components of the trauma system is paramount, and policymakers can use the information presented here to implement and refine health care systems to ensure safe, timely, affordable, and equitable access to neurotrauma care.

Union Efforts to Reduce COVID-19 Infections Among Grocery Store Workers.

Grocery store workers are essential workers, but often have not been provided with appropriate protection during the current pandemic. This report describes efforts made by one union local to protect workers, including negotiated paid sick leave and specific safety practices. Union representatives from 319 stores completed 1612 in-store surveys to assess compliance between 23 April 2020 and 31 August 2020. Employers provided the union with lists of workers confirmed to have COVID-19 infection through 31 December 2020. Worker infection rates were calculated using store employees represented by the union as the denominator and compared to cumulative county infection rates; outcome was dichotomized as rates higher or lower than background rates. Restrictions on reusable bags and management enforcement of customer mask usage were most strongly associated with COVID-19 rates lower than rates in the surrounding county. Stores that responded positively to worker complaints also had better outcomes. The union is currently engaging to promote improved ventilation and vaccination uptake.

Reflection on the enactment and impact of safety laws for regenerative medicine in Japan.

Japan's Act on the Safety of Regenerative Medicine (ASRM) created an innovative regulatory framework intended to safely promote the clinical development of stem cell-based interventions (SCBIs) while subjecting commercialized unproven SCBIs to greater scrutiny and accountability. This article reviews ASRM's origins, explains its unprecedented scope, and assesses how it envisions the regulation of SCBIs. This analysis is used to highlight three key insights that are pertinent to the current revision of the ASRM: clarifying how the concept of safety should be defined and assessed in research and clinical care settings; revisiting risk criteria for review of SCBIs; and taking stronger measures to support the transition from unproven interventions to evidence-based therapies. Finally, the article reflects on lessons drawn from Japanese experiences in dealing with unproven SCBIs for international endeavors to regulate SCBIs.

Composite performance indicators for helmet and seat-belt enforcement as imprecise data.

OBJECTIVES: Composite road safety performance indicators (RSPIs) are useful tools in regional road safety planning. Among the indicators and data calculated by the World Health Organization (WHO), information on the effectiveness of law enforcement on various risk factors for road casualties were provided, which can be considered as qualitative indicators. The purpose of this study is to analyze the performance indicators related to the percentage of helmet and seat-belt use versus the qualitative enforcement scores attributed by WHO. METHODS: This analysis was performed for 30 member states of WHO and will show how and with what degree of efficiency the qualitative output of the enforcement score acts versus the input percentage of seat-belt and helmet use. The qualitative nature of the output index has led us to depart the traditional analysis of crisp numerical indicators related to road safety performance and to consider data as imprecise or fuzzy indices. In this study we used two methods including imprecise DEA-based CIs and fuzzy DEA-based CIs, respectively. RESULTS: Results show that the clear score achieved by the Imprecise DEA-based CI model is easy to interpret and use. Whereas, in the Fuzzy DEA-based CI model, the fuzzy indicator scores obtained based on the level of several probabilities are strong in capturing the uncertainties related to human behavior. CONCLUSIONS: Both RSPIs are applicable with slight differences that were in the order of countries and the ease of reading the results. We also found that each method has different strengths and that the FDEA-based CIs method is more accurate and more in line with the inputs than the IDEA-based CIs method.

Public Opinion Perceptions, Private Support, and Public Actions of US Adults Regarding Gun Safety Policy.

Importance: Despite broad public support for gun safety policies, minimal policy implementation has occurred. Objective: To investigate factors that encourage greater private support for and public action on gun safety policy. Design, Setting, and Participants: Three studies were conducted: a public opinion survey (Study 1) was conducted from January 8 to 22, 2019, and 2 experiments (Studies 2 and 3) were conducted from August 27 to October 17, 2019, and April 15 to 21, 2020, respectively. Adults living in the US were eligible to participate in Studies 1 and 3. Students 18 years and older participating in a research experience program were eligible to participate in Study 2. Study 1 was administered online by Ipsos, a market research company. A nationally representative sample of 1000 US adults was obtained from Ipsos' online KnowledgePanel, of whom 508 completed the public opinion survey. For Study 2, which was conducted in a university laboratory, 354 participants were recruited from a university research pool, all of whom completed the study. Study 3 was administered online by the market research company YouGov, which identified 727 US gun owners from its opt-in panel, from which it constructed a census-matched sample of 400 participants. Exposures: Participants read a statement about the 2018 Marjory Stoneman Douglas High School shooting. Content was manipulated as a 2 (corrective information vs no corrective information) × 2 (system changeable vs system not changeable) between-subjects factorial design with random assignment. The corrective information included polling data highlighting widespread support among gun owners for several gun safety policies. System changeable described gun safety policies passed by Florida's legislature. Main Outcomes and Measures: Main outcomes were support for gun safety policies and public disclosure of support. Results: The 3 studies included a total of 1262 participants (Study 1: 508 participants; weighted mean [SD] age, 47.7 [17.5] years; 261.9 women [51.6%]; 82.5 Hispanic [16.2%] and 60.3 Black [11.9%]; Study 2: 354 participants; mean [SD] age, 20.0 [2.3] years; 232 women [65.9%]; 100 Asian [28.3%] and 37 Black [10.5%]; Study 3: 400 participants; weighted mean [SD] age, 52.1 [16.4] years; 187.3 women [46.8%]; 295.5 White [73.9%], 44.5 Hispanic [11.1%], and 32.4 Black [8.1%]). Study 1 found that 63% to 91% of gun owners and 83% to 93% of non-gun owners supported key gun safety policies, yet both groups significantly underestimated gun owners' support for these policies by between 12% and 31%. Studies 2 and 3 found that exposure to corrective information was associated with a small increase in support for 2 gun safety policies of between 4% and 15%, both in terms of participants' privately held beliefs and the beliefs they would be willing to share publicly. Conclusions and Relevance: This survey study found that many US adults failed to recognize that most gun owners support key gun safety policies. Correcting this misperception was associated with greater private and public support for gun safety policy.
